INFRARED REMOTE CONTROL TESTER

This circuit can be used to test any kinds of infrared remote controllers! It is simple and cheap and the circuit needs only 3V power to operate so 2×1.5V batteries can use to power the circuit, you can replace The LED using a 3V buzzer to produce a “beep” sound instead of light. but you may need to remove R2.

COMPONENTS YOU NEED

1.R1(resistor – 470K

2.R2 – 47 ohms(can be removed if a buzzer used)

3.SW1 is optional (not neccessary)

4.Q1 – any kind of cheap infrared photo transistor

5.BC327 PNP transistor

6.D1 – LED (any type of low current and color)

7.B1 – 3V battery
