Android doll

Robot with flashing LED eyes.

I sometimes attend the open day of the school where I work to explain programming with Kotlin for making Android apps. To decorate the stand on those open days, I made a small (30cm high) robot that draws attention with its blinking eyes.

On the inside is an ATtiny85 (see schema) with a simple program that makes the robot's LED eyes blink in a number of variations : sometimes alternately, sometimes at the same time, then quickly and then slowly again.

The power is taken directly from a USB cable. It can be plugged into my laptop and provides enough power to keep the LEDs blinking all day long.
