This projects features an infrared-based communication line between two Arduino cards using a diode and a photodiode functioning as the output and input respectively, using simple communication pri ...

Obstacle sensor, based on TCRT5000, uses infrared diode and photo-receiver to detect obstacle in front of it - emitted light just reflects back to the sensor. Onboard, you'll find voltage comparator, ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, makin… ...

A 3W IR diode transmits these new signals with the help of an N-channel MOSFET, giving it enough power to control each component, even without the proper line-of-sight orientation.
