The Little Bird Finch is our smallest programmable board. The Finch is a tiny little  board designed to add flashy functionality to your project without taking up a lot of room. 
It has an  ATtiny microcontroller on it so it’s actually pretty smart! You can sew on 4 LEDs and connect a battery and the LEDs will each flash at different times. 
The Finch is a quick and easy way to add twinkling lights to a project without any programming or a bulky Main Board. It’s also a great educational tool for showing a range of functionality without having to get out the computers.
If you’re an advanced user and want to re-program the Finch, the ICSP programming connectors are broken out on the back.

The Factory Code on the Finch is a simple flash and delay but you can make design a program of your own!

void setup() {
  pinMode(3, OUTPUT);
  pinMode(2, OUTPUT);
  pinMode(1, OUTPUT);
  pinMode(0, OUTPUT);
void loop() {
  digitalWrite(3, !digitalRead(3));
    digitalWrite(2, !digitalRead(2));
    digitalWrite(1, !digitalRead(1));
