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

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 ...

He used a stepper motor to rotate the object being scanned, and an Arduino for control, but the real novelty is the way he used the sensor. [Fernando] mounted a Sharp GP2D120X on vertical surface ...
