The first step is to populate and solder all the components on to the GENIE E18 Motor Control
Board.
When completed, this board is a PIC micro controller. Peripheral Interface Controllers (PIC) are
small computers that can be programmed and reprogrammed using the
GENIE Programming Editor
programming language to turn on/off various outputs depending on the state of various inputs.
The outputs being controlled in this case are:
2 x DC motors used to drive and steer the robot
1 x LED used to illuminate the line being followed
The inputs used to control these outputs are:
2 x LDR (Light Dependent Resistors) that act as line following sensors
The processing of all the information from the inputs and the control of the outputs is done by:
1 x GENIE E18 PIC Microcontroller Chip (18 pin shown in red above)
The motors are driven forward/reverse or clockwise/anti using a motor driver chip:
1 x L293D Motor Driver Chip (16 pin shown in yellow above)
