After we done on the second circuit construction, it it the time to test whether the circuit is functional or not.
The transmitter is supplied by 18V DC adapter.
The receiver is powered by a 6V battery consisting of four AA cells connected in series.
Hopefully, our project will run smoothly.
IR LED emits red light to send the signals
Testing the distance
Alhamdulillah... Both of the circuit that we test works well. The transmitter sends the signal while the receiver receives the signal as what we want.
