For many of them it was possible to make a parallel port programming cable from a DB25 connector, some wires from a floppy or hard drive cable, a couple of resistors and a 6 pin IDC. There was a brand of universal remotes that had a 6 pin 0.1″ pin header (or holes to solder one) inside the battery compartment.

We recently covered a more complex IR cloner, and if you need to put together a truly universal remote control, then this project may be just what you need. It’s a great way to make the invisible visible and add some helpful debug information into the mix. It’s not much of a leap to imagine what else you might be able to do with this information once you’ve received it – controlling your own projects, cloning the IR remote codes, automating remote control sequences etc. How to connect the TSOP4838 to an Arduino to read the transmitted codesīy using a cheap integrated IR receiver/decoder device (the venerable TSOP4838), most of the hard work is done for you! For a quick visual check that your remote is sending codes, it can easily drive a visible LED with just a resistor for a current-limit, and a capacitor to make the flickering easier to see.įor an encore, shows how to connect this up to an Arduino and how to use the “IRremote” library to see the actual data being transmitted when the buttons are pressed. By and large (when you can find them) they work fine, but what happens when they stop working? First port of call is to change the batteries, of course, but once you’ve tried that what do you do next? has your back with this simple but effective IR Remote Tester / Decoder. Even though some devices now use WiFi and Bluetooth, so much of our home entertainment equipment still relies on its own proprietary infrared remote control.
