LED Display Board
It is useful to test the program that running in PIC microcontroller before conecting to the actual devices. For the purpose, I have constructed a simple LED board to test the program on board. The board has 10 connection pins – 8 to the LEDs, 1 to +5v and 1 spare. In the action, each LED will indicates the status of a pin that it’s connected to.

Beside using it for testing, this board also can be include as a part of robot system i.e. as an indicator.
The connection header is designed to match with the controller board’s connection header. Module Connector Cable made of 10 way ribbon cable is used for the interface.
