ased on the previous step, I built the baseboard by soldering the NPN and resistors. Also, I add the wires which connected to Arduino digital pins.
Now it is time to locate the perfect place where the remote control placed on baseboard.
* Add the pins strip to the remote back heard.
* Place it in the center of the base.
* Make sure to keep away from the NPN & resistors.
* Mark it if necessarily.
* Make notches to separate some copper on the PCB stripboard.
* Apply soldering.
* Add wires, then solder it as well.
