The main difference when using this method is that the IR signal is not inverted as it would normally be when using a more common modulated IR receiver module. All of the Arduino code you need to ...

The 38-KHz IRTR module is a compact design of an infrared transmitter and receiver board created with the help of a couple of inexpensive components. This builds off of the IR Decoder that we explored ...

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!

Hardware Setup — Forepart Here’s the front-end circuit of the IR sniffer. The hardware will capture an IR code and retransmit it on demand. The schematic isn’t particularly complex. The IR receiver ...
