Review on 📱 DAOKI IR Infrared Wireless Remote Control Kit with 38KHZ Sensor Board for Arduino AVR PIC by Jonathan Olson

It took me too long to realize that the remote control sucks. No signal was sent (or generated) on my 6 keys! For a while I thought it was my code or something else I'm doing wrong, but then I found out about the serial monitor (in the IDE) as well as the activity indicator on the IR receiver. With these things, it was easy to see that the remote itself was junk. I figured out that I can use ANY IR remote and how to get the serial monitor to show the (hexadecimal) ID of each button, independent of the remote. Just use: Serial.println(results.value, HEX) For example, left arrow key ID is 0xFF22DD, serial monitor shows FF22DD. Just add 0x at the beginning to encode something. So easy! ;-) At least the IR receiver module works perfectly.
