I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

[Computergeek] made an Arduino Shield in order to use it as an ... he should probably have invited a resistor to the party the two IR LEDs are having.

He also went through the trouble of figuring out how to talk to it with an Arduino, which makes all ... used to pull the bill past an array of IR LEDs. The hardware uses these to scan the bill ...
