I want to build a line follower car.
This car has:
- Arduino Duemilanove
- Pololu QTR-8RC sensors
- RC car
- RC servo in the car (with three colors: black, red, orange)
I want the sensor to perform line following with the servo. For example, when a line is detected on the right, the servo will turn to right.
I used the Polulu library for the sensor and successfully detected different intensity. I need to know how to use those values to control the servo so the car can turn.
Also, I want to know how to connect the sensor and servo to the Arduino (which pin to which pin).
