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.

Atmel Atmega8 via USB Control Circuit
Hi, I have done recently attiny2313’l usb application (ATTINY2313 PIC16F88 USB UART converter circuit) then one needs at this time on I did with ATmega8. RS232 portion of the circuit 15 disuse I / O pin with a control board that communicates via usb I designed.
Available in 15 out of 15 relay circuit on a plaque by Cover with too much space. Relay outputs to observe instead I added diodes. We also work with 1,2,3 led to the exit to observe’ve added 3 relays. Circuit fine çalışıyor.atmega8 ‘s usb output due to the hassle of opening and closing process is a bit slow, but speed is sufficient for the control board.
