Components required: PCB, 9v Battery, Jumper Wires, PNP transistor, IR sensor (TSOP1738), LED, etc.
Circuit Diagram: Schematics
of IR Remote Control Tester
Description:
A PNP transistor A1015
will work as switch and TSOP1738 used as infrared sensor. When the IR waves received by the infrared
sensor it will make the transistor ON and the LED in the circuit will start
blinking.
Note: One can also used Buzzer in place of
LED
