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.

The build relies on an Arduino Uno as the brains. It’s equipped with an L293D motor driver shield ... Arduino an infrared sensor which can pick up signals from a simple IR remote control.

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 ...
