Outline
The project had the following outline:
- An autonomous unit following a dark line on a bright background
- Logic 1 (5V) when detector is over line, otherwise logic 0 (0V), CMOS technology
- Motors controlled by driver circuit
- Turn off when no line under detectors
- Steering right/left accomplished in 3 phases; straight ahead, 5 degree, and 10 degree
- Powered by a battery power-source
