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 ...

In this post I’ll discuss a popular and cheap infrared line tracker module – the HW-006 (v1.3). These modules, typically seen in line following ... Arduino Uno. This is the crude Arduino Sketch. This ...

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 ...
