Line Follower Robot (Without Microcontroller)
This is a simple line follower robot that is designed for the purpose of applying pwm control with opamps without using any microprocessor. 5 CNY70 reflective optical sensors and 4 NE555 opamps are used. To drive the motors I've used two mosfets (IRFZ44).
