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 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 ...

We’ve featured loads of IR Arduino projects and they are all exciting ... Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly time. A more complicated problem ...

If you have a few hours spare and fancy creating a new Arduino ... IR light to scatter in many directions. Some of this light is directed down into the screen, towards an array of 64 IR sensors.
