Hello I'm looking for the smallest and low power micro processor that i can program using arduino ide. I only need 1 or 2 pins to blink lights and a button push. Does anyone know a processor like that? I can do it with a attiny85 or 85 But they take a lot of power. This is for a gift I'm building for my wife and they need to take 1 or 2 coin cell batteries. Doesn't need to stay on long.
