This is the final circuit diagram for our line following buggy. We have included a switch to enable switching between the two pragrams. One for simple line following and the other for the instruction set. We have used a pull-down configuration for the switch. There has also been an LED included as an ouput. This is to be placed between our two LDR's inside the skirt so that there is a constant stable light source to calibrate the two LDR's against. This minimises any effect ambient light could have.
The rest of the circuit remains unchanged.
