Assalamualaikum wbt.
Done with the construction on the PCB Board, we proceed on testing the circuit. The circuit is supposed to be supplied with the 12V AC @ 15V DC suplier. At first, because of we do not have exactly 15V DC,we use the 12V DC and also 6V DC to test the circuit.
The circuit is tested, but then there are several problems occurs which is the signal is not transmitted to the receiver exactly like what it used to be.
Problems detected:
- Lots of noises
- LED of transmitter unit (to show power) doesn't show up
- Grounding are too far ( the breaks of small lines of carbon on PCB)
Next step: Troubleshooting
