Light Following Robot with Atmel ATtiny25

Light following robot circuit board on attiny25v not very complicated circuit Lithium-polymer battery provided with the circuit feeding the tiny H-bridge output (2N3904) drive motors are controlled with two LDR light is perceived. As you can see in the pictures material placement and cute 🙂 quite well also in the video seemed to be running very stable robot.
