We have a collection of almost 500+ Arduino projects with Code, Circuit Diagram, and detailed explanations completely free for everyone to build and learn on their own. The IR sensor has a 3-pin ...

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.

There are lot of applications where you need to decode the IR signals to operate some devices with IR remote. So in this tutorial, we are going to use the TSOP1838 IR receiver to build an IR Remote ...

The hybrid circuit depicted above also allows for both IR remote control code transmission (TSAL6400) and IR remote device decoding (TSOP38328). It requires the Arduino IRremote library by z3to ...

you can build your own IR detector. If you have a few remote control units around the house, you’ll appreciate this little circuit. The LED clearly indicates whether the remote control unit actually ...

During the development, I encountered an issue when lowering the power consumption. I utilized the deep sleep mode that awakes Arduino using external interrupt pins, but there are only two such pins ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown ...
