ATmega8 Line Follower Robot (LFR) Project – Part 2/2
Now that the mechanical assembly part is over,and we have completed the construction of left and right (L&R) infrared sensor cards. Since the MCU (ATmega8) cannot drive the dc motors directly, a dedicated motor driver circuit is used. The motor driver circuit here is based on a simple 16-pin IC (L293D) which can drive two …
