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… ...

How to connect the TSOP4838 to an Arduino to read the transmitted codes By using a cheap integrated IR receiver/decoder device (the venerable TSOP4838), most of the hard work is done for you!

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...

The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared emitter (IRED) is available for changing the hardware as an IR encoder.
