Simple Infrared LED and Photodiode Tester: This is a simple Infrared LED and Photodiode tester using Arduino-compatible microcontroller. Purpose: I received a new batch of IR LEDs and IR photodiodes. I need to test them before signing them off.

Today, I will show you the simplest way to test IR LED, including IR emitter and IR receiver LED. *** Buy IR LED on Banggood. https://sea.banggood.com/custlink/KDDy03t7W1. To test IR LED emitter: - Switch mode on multimeter to diode measurement. - Connect the red probe to the positive pin of the LED (Longer pin)

To alleviate this issue, I created an IR LED tester to reduce my workload. For the sake of portability, I plan to put the IR LED tester into a 4-cell battery box. With a simple circuit that utilizes the diode unidirectional conduction principle and a current limiting resistor, I was able to achieve the goal of testing IR LED extension cables.

2021年10月10日 · One way to directly test it is to connect another similar LED as a photodiode to your multimeter on a voltage range (eg. 200mV or 2V). Point one at the other and remove them from ambient light (in a cardboard box or whatever). If you turn the emitting LED on and off, you should see a change in the indicated voltage on your multimeter.

2017年4月24日 · Infrared LEDs -- light emitting diodes -- are used in many remote-control systems, such as television remotes and garage door openers. Infrared has a longer wavelength than visible light, so you cannot see it with the naked eye. This makes it harder to diagnose problems with infrared LEDs, as you cannot see whether the LED is lit or not.
