1. Simplified Circuit
2. What is a strip board?
3. Guide to connection on the strip board.


If you lost your circuit board, you can build another one using a prototyping board (strip board is recommended). You are allowed to build a simplified circuit to reduce the complexities of wiring the circuit.

It is your responsibility to source for the components yourself. Components can be provided to you but are subjected to availability.

A guide to wiring your circuit on the strip board is provided. It is your responsibility to check the correctness of the guide against the schematic of the simplified circuit provided.

Note that the simplified circuit has eliminated the ULN2803 inverter driver. Software written for the circuit with the driver will not run properly without modification.
