![]() If you don't see ATTinys as an option in the Tools -> Board menu you may have to place the files in the Arduino program folder. Save the boards.txt file and try starting Arduino. ![]() The ones we need are for ATTiny85, specifically ATTiny85 16 MHz (internal PLL 4.3 V BOD) but feel welcome to add others if you think they'll be useful. We'll need to copy the configurations we want to use in Arduino. Open the Prospective Boards.txt file that came with your ATTiny archive. C:\Projects\Arduino\hardware\ * Extract the contents of the archive into the "hardware" folder, so you have something like: C:\Projects\Arduino\hardware\tiny\ Create a new file in this folder called boards.txt. C:\Projects\Arduino\ Ensure this folder exists. For example, if the Arduino Sketch folder is. Installing this is a lot like installing a software library, but instead of putting it in a /libraries/ folder you'll make a /hardware/ folder inside of your Sketchbook Download it here Make sure Arduino is not running and follow the instructions in the ReadMe: * Ensure the "hardware" folder exists under the Arduino Sketch folder. You can do this with the ATTiny core for Arduino. Working with 5V (as opposed to 12V) will be easier for this tutorial, so that's what I recommend! You can try this sample code if you want to use your ATTiny with lights and a push button or touch sensor!Īfter you've installed Arduino you'll need to add support for the ATTiny. They come in strips, pixels, segments, modules of many varieties. 10 uF capacitor * 1 low value resistor (ex 47, 100, 220 Ohm) * A plain 1-color LED for testing If you're looking for addressable RGB LEDs try Adafruit's Neopixel line or WS2811. If you need one, these are plentiful at thrift shops!) * 5V Addressable LEDs (this tutorial assumes use of 3-wire WS2811/WS2812) Very helpful: *. What you'll need: * An ATTiny (this tutorial uses the ATTiny85-20PU) * a USB ISP AVR Programmer (My tutorial uses this one) * a breadboard * some jumpers or wires (color coded wires are really helpful) * a computer with the latest Arduino software installed (if you don't already have it, download here) * a 5V wall wart (Old cell phone power suppliers work wonderfully, double check them for a 5V output. The setup process is a little technical, but not too scary I promise, and you can use the familiar Arduino programming environment. Arduinos are wonderful and easy to work with, but there are some projects where you need a microcontroller, or want to add some interactivity but don't really want to dedicate a $20-30 board! At a little over $1/each (less in bulk) the ATTiny85 is a great chip for the job: it has 6 I/O pins and is capable of 16Mhz with minimal external components, is enough to work with many sensors, even drive popular addressable LEDs like Adafruit's NeoPixels, WS2811 strips.
