Design, Manufacture and Programming of the Circuit Board

As stated in the brief, this project centres around using a Genie E18 Peripheral Interface Control (PIC) circuit. The image below details the the layout of the board used to drive the mechanism used in the RoboCrab.

  

Following the circuit diagram each component was individually soldered onto the board ready for programming.

The flow diagram pictured above details how the circuit was programmed to drive RoboCrab. The two long 'interupt' runs represent what happens if either of the two push to make switches are pressed. Due to the fact that the LED's are are continually there was no need to write them into the programme.
