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 :(

Poll vote Result: Stepper Motor

Thank you all for voting on the poll, as of today I find the Stepper Motor to be the one which was the winner.

Okay so I have a few ideas, not going to poll them because I want to do the zany one first, then I'll move on to the more grounded and harder one.

Henry is a two-armed robot which will move along the ground using a set of arms connected to a servo, turning on and off with the press of a button, using a sort of crank shaft mechanism which moves both arms simultaneously.

The second is a locking mechanism which will work on a clock, which will be elaborated on in a different post.

For now, let me introduce: Henry the Crawler, this is a fairly basic idea which I plan to expand on with real blueprints later.

The idea is that I will be using an Arduino nano, connected to a breadboard which gives commands to a single stepper motor to make two arms throw itself forward.

The Single stepper motor will interact with the two arms via an axle, similar to a wind-up machine, only instead of a key there is a microcontroller and a button to turn it off and on.

Now I understand that there are issues with Henry, but I think he will be hilarious.

Now I thought the best way to do this would be to use the basic wind up mechanics for the actual moving parts in this robot. Doing this out of cardboard will be difficult but it seems like it is simple enough to build, just time consuming. As for the rod part I was able to ask a roommate for bamboo sticks to add onto it, so shout out to roommate for that.

As for the winder, spring and gear part of the components, I want to use one of the 28BYJ-48 5v dc stepper motors so as to make sure it is only one part which might be able to turn the beast on and off. I'll post more with the bread board and jumper wires later on.

Though not specified in the picture, I think arms with tendons in the actual moving parts might be kind of useless, and it is beyond my knowledge to be able to make them more utilized. I will likely keep the idea around for further projects.

Controlling Multiple Relays with Arduino: A Comprehensive Guide

Introduction

Relay modules are essential components in the world of electronics, allowing you to control high-power devices with low-voltage signals. When combined with the versatility of Arduino, you can create a wide range of automated systems. In this blog post, we'll explore how to control multiple relay modules using an Arduino board.

Understanding Relay Modules

A relay module typically consists of one or more relays, each with a control pin and a pair of output terminals. By applying a low voltage (usually 5V) to the control pin, you can switch the relay, connecting or disconnecting the output terminals. This allows you to control devices that require higher voltages and currents than the Arduino can directly provide.

Required Components

Arduino board (e.g., Uno, Nano)

Relay module (2-channel or more)

Jumper wires

Breadboard (optional)

Power supply (5V DC)

Circuit Diagram

Power Supply: Connect the 5V and GND pins of the relay module to the 5V and GND pins of the Arduino, respectively.

Relay Control: Connect the control pins of the relays to digital pins on the Arduino (e.g., pins 2, 3, 4, and 5).

Arduino Code

const int relayPins[] = {2, 3, 4, 5}; // Array to store relay pin numbers

void setup() {

for (int i = 0; i < 4; i++) {

pinMode(relayPins[i], OUTPUT);

}

}

void loop() {

// Control the relays as needed

digitalWrite(relayPins[0], HIGH); // Turn relay 1 ON

digitalWrite(relayPins[1], LOW); // Turn relay 2 OFF

// ... and so on

}

Explanation

Pin Definition: An array relayPins is used to store the pin numbers connected to the relay control pins.

Setup:

pinMode(relayPins[i], OUTPUT): This line sets each pin in the array as an output pin.

Loop:

digitalWrite(relayPins[i], HIGH/LOW): This line controls the state of a specific relay by setting the corresponding pin to HIGH (ON) or LOW (OFF).

Expanding the Functionality

Sensor-Based Control: Use sensors (e.g., temperature, light, motion) to trigger relay actions based on specific conditions.

Timer-Based Control: Employ the millis() function to implement time-based switching.

Remote Control: Combine with wireless modules (e.g., Bluetooth, Wi-Fi) to control the relays remotely.

Multiple Relay Modules: Connect multiple relay modules to the Arduino to control more devices.

Safety Considerations

Voltage and Current Ratings: Ensure that the relay module's voltage and current ratings are suitable for the load you're controlling.

Heat Dissipation: If controlling high-power loads, consider using heat sinks or other cooling measures.

Proper Wiring: Double-check all connections to avoid short circuits and potential damage.

By mastering the art of controlling multiple relay modules with Arduino, you can create a wide range of innovative projects, from home automation systems to industrial control applications.

Would you like to delve deeper into a specific application or have any other questions about relay module control with Arduino?
