Esplora Arduino game controller

The ESPLORA Arduino game controller Board is an Arduino-compatible microcontroller board based on the Arduino Leonardo. Unlike previous models, it comes equipped with a variety of built-in sensors for immediate use in interactions.

This guide is perfect for individuals interested in using Arduino, but who don’t want to dive into electronics right away. To learn how to use the ESPLORA Arduino game controller Board in a simple and clear manner, be sure to read the Getting Started with Esplora guide.

The ESPLORA Arduino game controller Board boasts onboard sound and light outputs, as well as multiple input sensors such as a joystick, slider, temperature sensor, accelerometer, microphone, and light sensor. Additionally, it offers the option to enhance its functions through two Tinker-kit input and output connectors and a socket for a color TFT LCD screen.

Similar to the Leonardo board, the ESPLORA Arduino game controller Board also utilizes an Atmega32U4 AVR microcontroller with a 16 MHz crystal oscillator. It features a micro USB connection that can function as a USB client device, such as a mouse or keyboard. Additionally, there is a reset push button located in the upper left corner of the board for restarting purposes.

There exist four indicators, each displaying a different status.

The green indicator shows if the board is currently being powered.

The L [yellow] connects directly to pin 13 on the micro-controller for easy accessibility.

The [yellow] LED indicates data being transmitted or received through the USB connection.

Within the board lies all the necessary components to support the microcontroller. To begin, just connect it to a computer using a USB cable. The ESPLORA Arduino game controller Board is also equipped with built-in USB communication, allowing it to function as a mouse or keyboard when connected to a computer. It also offers a virtual serial/COM port (CDC). This alters the behavior of the board, which is further explained on our getting started page. On this page, you can find all the instructions for configuring your board and utilizing the Arduino Software (IDE) for coding and electronics experimentation.

The transfer of data, both in and out.

The ESPLORA Arduino game controller Board features a classic gamepad design, including an analog joystick on the left and four push buttons on the right. It also comes equipped with several onboard inputs and outputs:

The analog joystick features a center push-button and two axes, designated as X and Y. There is also a central pushbutton for added functionality.

Arranged in a diamond formation are 4 push-buttons.

The slider for the linear potentiometer is located towards the bottom of the board.

A tool to capture the volume (amplitude) of the surrounding environment.

A sensor that detects light to measure brightness.

The temperature sensor measures the surrounding temperature.

A three-axis accelerometer detects the orientation of the board with respect to gravity, along the X, Y, and Z axes.

The buzzer has the ability to generate square-wave tones.

The RGB LED features Red, Green, and Blue elements that allow for color mixing and a bright display.

The TinkerKit Inputs allow for easy connection between the sensor modules and 3-pin connectors.

The TinkerKit Outputs allow for easy connection of the TinkerKit actuator modules via the 3-pin connectors.

The TFT display connector can be used for a color LCD screen, SD card, or any other devices utilizing the SPI protocol.

To fully utilize all available sensors, the board employs an analog multiplexer. This way, multiple input channels (excluding the 3-axis accelerometer) can share a single analog input of the microcontroller. Selecting which channel to read is done through four additional pins on the microcontroller.

Communication is essential in any relationship, whether it be personal or professional. It plays a crucial role in maintaining strong connections and fostering understanding between individuals. Effective communication allows for open and honest dialogue, facilitating problem-solving and building trust. Without good communication, misunderstandings can occur, leading to conflicts and strained relationships. Therefore, it is important to prioritize effective communication in every aspect of our lives.

The ESPLORA Arduino game controller Board for the Leonardo offers various features for connecting with a computer, another Arduino, or different micro-controllers. The ATmega32U4 enables serial (CDC) communication through USB and is recognized as a virtual com port on the computer. It also functions as a full speed USB 2.0 device and can be used with standard USB COM drivers. A .inf file is needed for Windows.

The Arduino software comes equipped with a serial monitor for easy transmission of text data to and from the board. Whenever data is being sent via the USB connection to the computer, the RX and TX LEDs will light up on the board. Additionally, the ATmega32U4 has SPI capability accessible through the SPI library. In addition, the Esplora can act as a standard keyboard and mouse, allowing you to use programming to manage these input devices via the Keyboard and Mouse libraries.

The act of creating computer software, also known as programming, involves writing code using various languages and tools. This process requires a combination of problem-solving skills, critical thinking and creativity. Programmers must constantly learn new techniques and adapt to ever-changing technology in order to produce high-quality programs.

To start using the Esplora with your Arduino software (download), simply choose “Esplora” from the Tools > Board menu. For more information, refer to the getting started page. The ATmega32U4 on the Esplora comes pre-loaded with a boot-loader, enabling you to upload new code without an external hardware programmer.

The AVR109 protocol is the chosen method of communication. To avoid using the bootloader, you can program the microcontroller through the ICSP header. Additional instructions are available for reference.

A dedicated library for the Esplora simplifies writing sketches, with methods available for reading sensors and controlling onboard outputs. These high-level methods also perform pre-processing of data, such as converting temperature readings to degrees Fahrenheit or Celsius. Additionally, the library allows easy access to outputs like the RGB LED. For further information and examples, please refer to the Esplora library reference page.

The automatic reset and bootloader activation are key components in the software’s functioning.

Rather than relying on the physical reset button, the Esplora utilizes a software-based reset triggered by opening and then closing the virtual serial/COM port (CDC) at 1200 baud. This initiates a processor reset, temporarily cutting off the USB connection to the computer and causing the virtual port to disappear. The boot-loader remains active for approximately 8 seconds before it can also be activated by pressing the reset button on the Esplora.

Please be aware that upon initial power up, the board will launch the user sketch instead of the boot-loader, if available. Due to the specific reset process of the Esplora, it is most effective to allow the Arduino software to attempt a reset before uploading, especially if you typically press the reset button before uploading on other boards. However, in the event that the software is unable to reset the board, you can manually initiate the boot-loader by pressing the reset button on the board.

The USB port is equipped with overcurrent protection to prevent any potential damage.

The ESPLORA Arduino game controller Board comes equipped with a re-settable poly-fuse to safeguard your computer’s USB ports against shorts and over-current. While most computers have built-in protection, the fuse adds an additional level of security. In the case of a short or overload exceeding 500 mA, the fuse will disconnect the connection until the issue is resolved.

Regarding the appearance of this object, its external features will be discussed.

The ESPLORA Arduino game controller Board PCB has a maximum size of 6.5 inches in length and 2.4 inches in width. The USB and TinkerKit connectors extend beyond the width dimension. Additionally, there are four screw holes that allow for attachment to a surface or case.

[ziekkfreak2-0]

On one hand, I hate my robotics teacher for teaching us the same lesson on python loops we've been learning for half the damn school year, then expecting us to make an innovative robot in 3 weeks when arduino is based on C++.

I was gonna counter that with something else, but as I wrote it I realized just how stupid it actually is. Fuck it. Venting time.

NO CUZ I CAN'T UNDERSTAND THIS GUY. WDYM "Programming's easy! You learn the basics, and from there you make your own solutions." ??? That's not verbatim but. STILL.

I'll give him a bit of credit, he taught us the basics of arduino. The proper syntax, loops, variables, functions, motor control, sensors, etc. But for god's sake, that limited pool of knowledge can only get you enough to make a mini car! It would've been nice to learn about fading LEDs, integer overflow, pointers vs the actual value in a variable, OR EVEN WHAT DOCUMENTATION IS. YEAH. DOCUMENTATION. THE LITERAL OFFICIAL EXPLANATION FOR KEY FEATURES IN PROGRAMMING LANGUAGES.

But suddenly its OUR fault our code doesn't work because "I taught you the basics. If you don't understand, that means you're not listening during my classes." MAYBE IF YOU STOPPED TEACHING US WHAT A FUCKING FOR LOOP IS, WE'D HAVE A REASON TO LISTEN. Majority of my understanding of robotics are a product of self study and receiving help from my family and their long list of IT contacts.

Not only that, HE is the one that approves of our robotics projects. If YOUR students can't complete the project YOU personally approved of, isn't that an error on your part? You should know what your students are capable of making. You should know because they should only know WHAT YOU TEACH THEM. So surprise surprise when your students feel like they're forced to hire people to do their projects, all because of your failure to teach them the skills they needed to do it themselves.

The only people getting a passing grade in this class are gonna be those that are either rich or have a lot of contacts. What a fucking joke.

And don't be mistaken, this is NOT the complaint of someone who doesn't understand programming. I consistently get 90% and above on his exams and do coding for fun. I'm complaining on behalf of my classmates who weren't as lucky as me, in that I have way more people to ask help from.

"100% working by this week" my ass. Actually teach us something relevant for once.

hi. robotics question: i want an electric motor that receives input to control its force, and outputs its position. im kinda confused with different kinds of motors. controlling force is easy, right?

in terms of scale, im talking about an arduino prototype so pretty small but im fine if the motor is big enough to have its own power cable.

yeah im a programmer i dont know much about hardware :p

someone please fix me if i'm wrong, FRC uses a pretty self-contained ecosystem so I actually have no prior knowledge to answer this lol

but! based on some research, it sounds like torque control in a DC motor can be achieved by limiting the current to the motor (versus speed control, by setting voltage).[1][2] look for brushed DC motors with built-in encoders, that's the part that will tell you the motor's position. encoders can be absolute (tells you where the rotor is wrt some fixed "zero" position, consistent across power cycles) or relative/incremental (just tells you how far you've gone since you started/that you've taken a step). i'm not sure what kind of circuitry you might need to handle the current control, although looking for something marketed for arduino makes sense as a first step.[3]

there are also AC motors, brushless DC (BLDC) motors, and stepper motors, and they all have more complex control schemes that I know next to nothing about!

Arduino Due vs. Mega: A Comprehensive Comparison

What is Arduino Due and Mega?

The Arduino platform has revolutionized the world of DIY electronics, providing hobbyists and professionals alike with versatile and powerful microcontroller boards. Among the myriad of options, the Arduino Due and Arduino Mega stand out for their advanced features and robust performance. The Arduino Due, introduced in 2012, is the first Arduino board based on a 32-bit ARM core microcontroller, the Atmel SAM3X8E. In contrast, the Arduino Mega, built around the 8-bit ATmega2560 microcontroller, is known for its abundant I/O pins and memory. Understanding the differences between these two boards can help in selecting the right one for specific projects, enhancing both functionality and efficiency.

Processing Power and Performance

The processing capabilities of the Arduino Due and Mega are distinctly different, primarily due to their core microcontrollers. The Arduino Due, with its 32-bit ARM Cortex-M3 processor running at 84 MHz, offers significantly higher processing power compared to the Arduino Mega's 8-bit ATmega2560, which operates at 16 MHz. This difference in architecture and clock speed means that the Due can handle more complex calculations and tasks faster and more efficiently than the Mega. For projects requiring high computational power, such as real-time data processing or handling multiple sensors simultaneously, the Due is the superior choice. However, for simpler tasks, the Mega's processing power may suffice.

Memory and Storage Capabilities

Memory is another critical aspect where the Arduino Due and Mega diverge. The Arduino Due is equipped with 512 KB of flash memory for code storage and 96 KB of SRAM for data. On the other hand, the Arduino Mega has 256 KB of flash memory and 8 KB of SRAM. Additionally, the Due features a Direct Memory Access (DMA) controller, which allows for efficient memory operations, freeing up the CPU to handle other tasks. These memory enhancements make the Due more suitable for applications requiring large codebases and significant data handling, such as advanced robotics or sophisticated control systems. The Mega, with its more modest memory, is ideal for less demanding applications.

Input/Output Capabilities and Expansion

Both the Arduino Due and Mega are renowned for their extensive input/output (I/O) capabilities, yet they cater to different needs. The Mega boasts a whopping 54 digital I/O pins, 16 analog inputs, and 4 UARTs, making it ideal for projects that require multiple sensors, actuators, or communication interfaces. The Due, while offering fewer digital I/O pins at 54, includes 12 analog inputs and 4 UARTs, along with additional features like two DAC outputs for analog signal generation and enhanced PWM capabilities. These features provide the Due with superior analog output capabilities, making it suitable for applications like audio processing or advanced signal generation.

Power Consumption and Compatibility

Power consumption and compatibility are practical considerations when choosing between the Arduino Due and Mega. The Due operates at 3.3V logic levels, which makes it more power-efficient than the Mega, which uses 5V logic levels. This lower voltage operation is beneficial for battery-powered projects where energy efficiency is crucial. However, the 3.3V logic also means that the Due is not directly compatible with 5V components without level shifters. The Mega, with its 5V logic, offers broader compatibility with existing Arduino shields and components, making it a versatile choice for a wide range of projects. Understanding these power and compatibility nuances can help in making an informed decision based on the project's specific requirements.

DeerHead EMC-V1 baby pictures.. She doesn't even have all of her leg servos yet 🥺 (EMC stands for "Electro-Mechanical Chihuahua"!)

Her snout is a bit huge for this first run, but really this is just a draft while the 3D printer is broken; the LED matrix in her head was also defective right out of the package, as it turns out; so because it's also a little heavy, I probably won't end up using it! That's okay because atleast for the Arduino Uno, running both 15 servoes and the 64 pixel screen animations at once could be a bit much! I'm thinking of getting the hardware up and at 'em first, and making sure that I can program it to say, do a little dance for now to show that I'm up for the challenge of animating servoes with this driver library (right now I'm just testing with a live servo control program), and then I want to upgrade to a Raspberry Pi brain so that I can start giving her autonomy! When I do that, I'm going to atleast want two buttons; a back and head button to sense affection and love! Or scoulding with a tap on the head, but that might be much to program for something I'd never really need to do with a robot I programmed XD unless it ended up being more autonomous than I'm realisitcally imagining it being! I'll also want a gyro sensor, so that she'll be able to tell if she's fallen over (maybe combined with soft buttons on her front paws sensing that they aren't touching the ground), and self-right! She will also have a distance sensor on her chest to avoid bumping into things, and for a general sense of depth; and beside that, a microphone (connected to a voice recognition module? I feel like Raspberry Pi wouldn't need that, I haven't looked into it though), to understand voice commands.. Or just "I love you" whilst receiving cuddles 😄 and of course, there would be a speaker, likely in the back of the head or also near the distance sensor depending on the size; for this maybe I can use some old furby boom parts I have laying around 😆 I'd probably need a module for the speaker though, so the Pi knows it's a speaker, and that'd probably come with another speaker.. And to power it all? A six volt LIPO battery! Or would six volts be anywhere near enough for all that combined with running the programming of the robot? Such I'd have to research lol, but furthermore.. I welcome EMC-V1 to the world!!! And tomorrow my new servoes will come in, hopefully she'll be able to walk too by then 😄

HOW DO YOU START MAKING A GAME?

hihihihi- I'm adding to this because I want everyone to make games. My current top recommendations for books is A Playful Production Process, Rule of Play is a classic, so is Game Feel

This is long- so get ready

Other engines

Construct 3: Browser based game stuff!

Pulp: Extremely similar to Bitsy- make games for the PlayDate

PICO-8: Make tiny games and programs for a fantasy console!

LÖVE: Lua based 2D game framework!

Scratch: Educational engine, chances are if you're under a certain age you've had a school program use this!

microStudio: More browser based engine stuff!

babylon.js: Open source engine

For games adjacent things like alternative controllers, events, or installations

LIKELIKE online: Arts based open source online art gallery, remixable on glitch- there's even a template

Processing: Open source, 20 years of documentation, and super flexible if you wanna be experimental

Arduino: Make physical games using programming, or robots, or escape rooms!

Makey-Makey: Much simpler plug and play Arduino!

Okay but how do I make a game?

Fast answer- you just start. But a pretty straight forward workflow would be

Write down ideas, make flowcharts of ideas, scripts, mechanical descriptions. From that think of how systems interact

Paper prototype, see what works and doesn't work when playing through things without being restricted to programming

Jam, fail often and fast because each project is a lot like a sketch- they take a long time to do though. the quicker you are to kill your darlings and start anew the faster you'll get better

Do a game deconstruction- break it down into tiny pieces and stare into it. What made it fun? What were the small things that stuck out to you?

"But I want to make a complicated-"

Shhhh- no you don't. You'll burn out. Make the cube move first. Make it jump. Does the jumping feel good? No? Start over. Make the cube move again, but slightly differently- does the jump feel good yet? No? START OVER. As soon as you get stuck, abandon what you're doing and start over

And I'm not kidding, game making is an iterative process. The more projects you do the better, faster, and easier it gets. If you whittle away on something you'll never finish

Okay, jump feels good now, great now interact with something in the scene. So on and so forth until you have scripts you like and understand and these become your building blocks for projects

Make the smallest thing you can- smaller, smallerSMALLER- here's a breakdown of a dating sim game with a final 3-4 hours of content per playthrough, similar to something like Hatoful Boyfriend or Doki Doki Literature Club

Need To Have

Title card and a way to start the game.

A dialogue system including the ability to show text, click on buttons, and track choices.

Includes both NPC and player names along with dialogue.

One dateable character including tracking relationship points with the player, one friendship cutscene, one romantic cutscene, and one final cutscene.

Ending card and credits.

Want To Have

In addition to above:

An option screen that changes basic user interface, save and load system, player name input with pronouns, music volume and quality of life settings, so on.

An external narrative building up the world in which the game is played including a mystery for the player to solve.

Four dateable characters with individual narratives including 3 friendship cutscenes, 3 romantic cutscenes, and a final ending cutscene for each.

A resolution to the mystery.

Dream To Have

In addition to above:

A hidden menu that allows the character to make interesting alterations to the game and becoming the antagonist of the mystery

Mystery narrative is branching with several endings where the player can either fail or succeed without dating any of the characters

Friend only narrative choices and ending.

Two extra gag romance characters with diverge narratives unlike the others in the game

Jealousy/approval between characters depending on narrative choices. 

Options to create poly relationships between compatible characters, options to betray or cheat on characters, and options to matchmake characters without dating them.

Multiple endings to resolve the mystery including hidden antagonist role.

I often reference this tiktok on how everything piles up

Game making takes a long time and wildly complex very fast. For my timelines I add a minimum of 3 months for each year.

Quick and dirty advice for once you've got something going

Call your grant officers if you got local funding, it’s their job to answer your questions!

Research the desired outcomes before asking someone for money; be that the government, a publisher, or yourself

Never pay for event submissions or showcases until you’re making significant revenue if you don’t have to, I suggest following Game Conference Guide’s calendar

Even if you’re working for free track your hours and costs so if/when you are making budgets in the future you know how fast you and your team work

Learn when to say something is good enough; cut mechanics or features early and often to avoid the project ballooning out of scope

Don’t quit your day job until it makes sense- it’s more sustainable to work on something without funding if you’re still able to pay your bills

Shipped is the best feature, some great advice from Mark Darrah

Make smaller, shittier, and messier games more often

Go forth, make games, then tell me about them and I'll play them if I can. I love when folks make games- you can do it!

🎮 HEY I WANNA MAKE A GAME! 🎮

Yeah I getcha. I was once like you. Pure and naive. Great news. I AM STILL PURE AND NAIVE, GAME DEV IS FUN! But where to start?

To start, here are a couple of entry level softwares you can use! source: I just made a game called In Stars and Time and people are asking me how to start making vidy gaems. Now, without further ado:

SOFTWARES AND ENGINES FOR PEOPLE WHO DON'T KNOW HOW TO CODE!!!

Ren'py (and also a link to it if you click here do it): THE visual novel software. Comic artists, look no further ✨Pros: It's free! It's simple! It has great documentation! It has a bunch of plugins and UI stuff and assets for you to buy! It can be used even if you have LITERALLY no programming experience! (You'll just need to read the doc a bunch) You can also port your game to a BUNCH of consoles! ✨Cons: None really <3 Some games to look at: Doki Doki Literature Club, Bad End Theater, Butterfly Soup

Twine: Great for text-based games! GREAT FOR WRITERS WHO DONT WANNA DRAW!!!!!!!!! (but you can draw if you want) ✨Pros: It's free! It's simple! It's versatile! It has great documentation! It can be used even if you have LITERALLY no programming experience! (You'll just need to read the doc a bunch) ✨Cons: You can add pictures, but it's a pain. Some games to look at: The Uncle Who Works For Nintendo, Queers In love At The End of The World, Escape Velocity

Bitsy: Little topdown games! ✨Pros: It's free! It's simple! It's (somewhat) intuitive! It has great documentation! It can be used even if you have LITERALLY no programming experience! You can make everything in it, from text to sprites to code! Those games sure are small! ✨Cons: Those games sure are small. This is to make THE simplest game. Barely any animation for your sprites, can barely fit a line of text in there. But honestly, the restrictions are refreshing! Some games to look at: honestly I haven't played that many bitsy games because i am a fake gamer. The picture above is from Under A Star Called Sun though and that looks so pretty

RPGMaker: To make RPGs! LIKE ME!!!!! NOTE: I recommend getting the latest version if you can, but all have their pros and cons. You can get a better idea by looking at this post. ✨Pros: Literally everything you need to make an RPG. Has a tutorial inside the software itself that will teach you the basics. Pretty simple to understand, even if you have no coding experience! Also I made a post helping you out with RPGMaker right here! ✨Cons: Some stuff can be hard to figure out. Also, the latest version is expensive. Get it on sale! Some games to look at: Yume Nikki, Hylics, In Stars and Time (hehe. I made it)

engine.lol: collage worlds! it is relatively new so I don't know much about it, but it seems fascinating. picture is from Garden! NOTE: There's a bunch of smaller engines to find out there. Just yesterday I found out there's an Idle Game Maker made by the Cookie Clicker creator. Isn't life wonderful?

✨more advice under the cut. this is Long ok✨

ENGINES I KNOW NOTHING ABOUT AND THEY SEEM HARD BUT ALSO GIVE IT A TRY I GUESS!!!! :

Unity and Unreal: I don't know anything about those! That looks hard to learn! But indie devs use them! It seems expensive! Follow your dreams though! Don't ask me how!

GameMaker: Wuh I just don't know anything about it either! I just know it's now free if your game is non-commercial (aka, you're not selling it), and Undertale was made on it! It seems good! You probably need some coding experience though!!!

Godot: Man I know even less about this one. Heard good things though!

BUNCHA RANDOM ADVICE!!!!

-Make something small first! Try making simple: a character is in a room, and exits the room. The character can look around, decide to take an item with them, can leave, and maybe the door is locked and you have to find the key. Figuring out how to code something like that, whether it is as a fully text-based game or as an RPGMaker map, should be a good start to figure out how your software of choice works!

-After that, if you have an idea, try first to make the simplest version of that idea. For my timeloop RPG, my simplest version was two rooms: first room you can walk in, second room with the King, where a cutscene automatically plays and the battle starts, you immediately die, and loop back to the first room, with the text from this point on reflecting this change. I think I also added a loop counter. This helped me figure out the most important thing: Can This Game Be Made? After that, the rest is just fun stuff. So if you want to make a dating sim, try and figure out how to add choices, and how to have affection points go up and down depending on your choices! If you want to make a platformer, figure out how to make your character move and jump and how to create a simple level! If you just want to make a kinetic visual novel with no choices, figure out how to add text, and how to add portraits! You'll be surprised at how powerful you'll feel after having figured even those simple things out.

-If you have a programming problem or just get confused, never underestimate the power of asking Google! You most likely won't be the only person asking this question, and you will learn some useful tips! If you are powerful enough, you can even… Ask people??? On forums??? Not me though.

-Yeah I know you probably want to make Your Big Idea RIGHT NOW but please. Make a smaller prototype first. You need to get that experience. Trust me.

-If you are not a womanthing of many skills like me, you might realize you need help. Maybe you need an artist, or a programmer. So! Game jams on itch.io are a great way to get to work and meet other game devs that have different strengths! Or ask around! Maybe your artist friend secretly always wanted to draw for a game. Ask! Collaborate! Have fun!!!

I hope that was useful! If it was. Maybe. You'd like to buy me a coffee. Or maybe you could check out my comics and games. Or just my new critically acclaimed game In Stars and Time. If you want. Ok bye
