The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The little sensor has a serial interface and can recognize quite a ... and there’s a tiny optical sensor onboard along with an IR LED. Of course, you could send other keys than media controls.

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair. An Arduino Mega Pro ...

Arduino is a great way for today ... Analog pin A4 is for the temperature sensor, digital pin D2 is for the infrared receiver module, and digital pins D4, D7, and D8 handle the LED display. Looking at ...
