Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagi… ...

Living proof is this human-following robot/car that was build by the YouTuber over at DIY Builder, which relies on an Arduino Uno as the brain of the device. The video that you can find embedded ...

The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.
