SERVO DISTANCE INDICATOR USING ARDUINO UNO

INTRODUCTION

Distance measurement is a fundamental concept in various fields, including robotics, automation, and security systems. One common and efficient way to by emitting sound waves and calculating the time it takes for the waves to reflect back from an object, allowing accurate measurement of distance without physical contact.

In this project, we will use an HC-SR04 Ultrasonic Sensor in conjunction with an Arduino microcontroller to measure the distance between the sensor and an object. The sensor emits ultrasonic waves and measures the time it takes for the waves to return after reflecting off the object. By using the speed of sound and the time measured, the distance is calculated. This simple yet powerful setup can be applied in a variety of real-world applications such as obstacle detection in robots, parking assistance systems, and automatic door operations.

WORKING PRINCIPLE

1. Servo Movement: The servo motor rotates to different angles (0° to 180°). The ultrasonic sensor is mounted on top of the servo and moves with it.

2. Distance Measurement: At each position, the ultrasonic sensor sends out an ultrasonic pulse and waits for the echo to return after hitting an object. The Arduino records the time taken for the echo to return.

3. Distance Calculation: The Arduino calculates the distance to the object based on the time recorded and the speed of sound (0.0343 cm/µs).

4. Servo as Indicator: The servo motor's position provides a physical indication of the direction of the detected object. As the servo moves across a range of Image map out objects in different directions based on distance.

5. Visual Output: The Arduino can also send the distance and angle data to the serial monitor, creating a real-time visual representation of the detected object positions.

APPLICATIONS

1. Autonomous Robots and Vehicles

2. Radar Systems

3. Parking Assistance

4. Security Systems

5. Environmental Scanning in Drones

6. Warehouse Management and Automation

7. Industrial Automation

8. Robotic Arm Guidance

9. Collision Avoidance in UAVs/Robots

10.Interactive Displays or Art Installations

11.Smart Doors and Gates

CONCLUSION

The Servo Distance Indicator Project successfully demonstrates the integration of an ultrasonic sensor and a servo motor to create an effective distance measurement an object, the project provides real-time feedback through the movement of a servo motor, which indicates the measured distance via a visual representation.

PCB of the day! Adafruit I2C Stemma QT Rotary Encoder Breakout with NeoPixel - STEMMA QT / Qwiic 🔧🔄🎛️

Rotary encoders are soooo much fun! Twist them this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little detents for tactile feedback. But, if you've ever tried to add encoders to your project, you know they're a real challenge to use: timers, interrupts, debouncing…

This Stemma QT breakout makes all that frustration disappear - solder in any 'standard' PEC11-pinout rotary encoder with or without a push switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying over I2C. Plug it in with a Stemma QT cable for instant rotary goodness with any microcontroller from an Arduino UNO up to a Raspberry Pi.

You can use our Arduino library to control and read data with any compatible microcontroller. We also have CircuitPython/Python code for use with computers or single-board Linux boards.

Creating a GPS Treasure Box

Andrew did a write up of one of his projects that we would love to share. We wish you all a happy ❤️Valentines Day!❤️

---

Many years ago I came across the idea for a GPS treasure box, from a post originally by Kenton Harris (I think - apologies if it was somebody else). Some called it a reverse geocache too, but in simple terms, it's a locked box that only opens at a certain location. 

The idea behind the box was a very simple interaction - one button, and a screen. The process would go like this:

Press button

Screen lights up, and GPS begins scanning

Screen tells you how many attempts you have left

Once GPS has location, the distance from the target location in kilometers is shown

One attempt is removed from total # of attempts

Screen turns off

Eventually, the target location would be found (and the box unlocks), or the attempts will run out and the box will be sealed shut forever! 

Inspired to create a fun adventure for myself and a friend on a weekend in Spain, I ordered all the relevant components including GPS module, Arduino Uno, batteries and a servo motor to lock the box. This was back in January of 2020. 

Ah, how times change...

---

Fast forward to January of 2023. I'd moved back to Sydney years prior and still had all of these components sitting around. I knew I'd get to this project one day. 

I came across a local makerspace with access to a laser cutter. This was the missing ingredient I needed - not only were there the facilities I needed to create the treasure box, there was also vibrant community of people who had done similar things before. 

I started out by gathering some code to power the project, and thankfully found a number of helpful repositories on Github. 

I was able to clone one, and adapt it to the paricular hardware and display I was using pretty easily. Annoyingly I had to learn all about Baud rates and GPS modules - but I'm glad I did as I'm sure it will contribute to projects in the future. 

---

At long last, the finished project was here. 

Not too shabby I thought, but it was time to put it to the test.

I enlisted the help of my girlfriend. We began at home and she pressed the button. 

As a guess, she told me to head to Pyrmont, an inner-city suburb. So off we drove.

Getting warmer! And still with heaps of attempts left.

With the sun setting, we headed to a nice spot in Rose Bay, by the water. 

It was close enough to continue on foot, so we decided to put the dog in a backpack (I didn't realise prior that he was not allowed in Sydney Harbour National Park, so I hope this was an OK compromise! Apologies to the national parks service). 

---

Here, my true colours were revealed. I'd actually added some extra code into the mix - getting the box to ask a very important question on my behalf. 

And sure enough, the box opened on cue, revealing an exciting treasure hidden within!

First ATTINY85 project!

(warning: video has actual flashing LED lights)

[ Video ID: A breadboard with a Blue LED on top of an 8-pin DIP Integrated Circuit on it. The Blue LED is flashing rapidly. There are other components on the breadboard in the background. End ID ]

Last week I bought some ATTINY85 Microprocessors to experiment and work with :) With my W65C02 project on hold until I can afford an oscilliscope, and my Radio project delayed because I can’t quite figure out how to reverse engineer the 8 pins on the volume knob, I wanted something else to work with. I’ve been wanting to mess with Atmel microprocessors (Arduino Uno runs on an Atmel ATMEGA328), and now’s a good chance!

I’m jumping straight to assembly with the ATTINY85; I don’t know any C/C++ code, and also I’m familiar with other processor Assembly languages, so I might as well. And other than different names for functions, it’s been pretty easy so far! Something I’m not used to is that this processor, despite being pathetically tiny, has 32 registers; I’m used to working with 8 Max.

Anyways, for the code explanation: When the processor first starts, it turns on PINB0, which is physical pin 5 on the processor. Then, after counting to 256 256 times, it turns off PINB0 for another 256^256 counts. I’m away from home while writing this, so my notes arn’t here, but if I remember correctly it came up to 200k microseconds? That adds up to about 400 nano seconds per on/off cycle, or 2.5 flashes per second. I can add in another loop to make it last longer, but before I do that I’d like to look about to see if there’s a smarter way to tackle this.

My next step after this, is to figure out how to get this processor to read digital inputs: My next project is to finally do something with my box of telephone rotary dials. I already have one spec’ed out for breadboard testing. I would LOVE to show it, but Tumblr has a One Video Per Post limit :(

The Ugly Project

Over the course of my 30+ year career as a Technical & Training Representative for Hunter Engineering Company I saved pretty much everything. When I retired, I decided to check out sim-racing, which is hardware and software that attempts to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. I started with iRacing, then moved to Assetto Corsa Competizione. I'm not very good, but I'm having fun.

In 2023 I found out about motion simulators, which as you may imaging, attempt to simulate the physical movement of the car being driven in the game. I can't afford to purchase one, so using YouTube for guidance, I thought I would try to make one using all of the scrap hardware I had filling up my barn.

I decided to start simple, with a rig with just one motor that simulated traction-loss. I did have to purchase some special items such as a 12VDC motor originally meant for dump truck tarp systems, an Arduino Uno, a 12 Volt power supply, things like that.

The prototype is all together now, and it does work - mostly. There is still a lot of tweaking to do regarding the control settings and programing.

I realize the captions are not going to mean much for most people, sorry.

HW 2: Deep Diver - The Enclosure 🐠

For my midterm physical computing project, I used photoresistors as a game controller to control a fish character inside a P5.js-based video game. By covering or uncovering the sensors, the fish swims up, down, left, or right depending on which direction is triggered. Since the game was aquatic-themed, I wanted to design an enclosure that matched the environment and enhanced the interaction. That’s how I came up with Deep Dover, a controller enclosure styled after a fish tank that would serve as both a protective shell and a visual element to support the game’s narrative.

I started the process by designing a custom acrylic case using MakerCase and laser-cutting it in the Spelman Innovation Lab. I chose a translucent blue acrylic to reflect the water aesthetic and designed the dimensions to be roughly 5 x 7 x 5 inches—just big enough to hold the Arduino Uno, breadboard, and sensors comfortably. The top half of the enclosure was built from this laser-cut acrylic, while the bottom half was a found plastic container that I cleaned thoroughly. I filled the container with water and tinted it using blue ink, then added handmade Play-Doh rocks to simulate the feel of a real aquarium. Once I had both parts ready, I hot-glued the acrylic case together and mounted it on top of the container to complete the enclosure.

To integrate the electronics, I drilled holes in the acrylic for both photoresistors and the USB cable that powers the Arduino. I then disassembled my controller setup temporarily and mounted the Arduino on the bottom shelf inside the box and the breadboard above it. Once the core components were fixed in place, I fed the two light sensors through the pre-drilled holes, aligning them so users could interact with the sensors directly from the outside. The sensors worked well within the design and were easy to access without interfering with gameplay. Placement was especially important to ensure that the photoresistors were responsive to ambient light changes and player interaction.

There were definitely some challenges throughout this process. Making sure the enclosure was the right size to hold everything without being overly bulky required a few adjustments during assembly. Fitting the Arduino and breadboard into the limited space inside the case was also a bit difficult, and I had to be cautious not to tangle or overstress the wiring. The biggest risk I took was incorporating water into the design—something I probably won’t do again unless I have more advanced waterproofing methods available. That said, I was extremely careful with sealing, and nothing got wet. I think the result was not only practical but genuinely cute, and I was proud of how I merged functionality with a strong visual theme.

Seeing the final project come together made me realize how valuable enclosure design is—not just for aesthetic purposes but also to protect the hardware, organize components, and create an immersive experience for the user. I enjoyed being able to incorporate my artistic interests in design and storytelling into a technical assignment, which made this one of the more rewarding projects I've worked on this semester. If I were to do this again, I might explore other materials, add LED lighting for more atmosphere, or integrate sound elements to give the enclosure even more personality.

Overall, building Deep Dover helped me grow as both a designer and a developer. I got to test my creative problem-solving skills, explore sensor integration in a hands-on way, and create something that felt like a real fusion of code, electronics, and art. Even with the risks, the build turned out well, and it taught me that when you take the time to design an enclosure thoughtfully, it can truly bring your whole project to life.
