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 ...

In the real world, missile systems use advanced radars, infrared sensors ... targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo.
