Functions on the board were tested by connecting a computer and feeding raw serial commands through a terminal. Not everything worked well. The transistor controlled outputs did not all work.

Testing voltage on the PCB

The red led and laser module would not turn off after they were activated. This was not a problem with programming since the output stayed active after disconnecting power.

Hung output

The problem seemed to be on the control board. One of the manufactured PCBs was populated with components and replaced the homemade board.

All the inputs and outputs worked easily the first time. The red LED and laser functioned as expected. The infrared emitter was tested by sending meaningless data and it worked properly.
