While a line-following robot may not be the newest project idea in the book, this one from [Edison Science] is a clean build using modern components and gets a good speed thanks to PID control ...

This article explains proportional integral derivative (PID) control, including the math behind it, with the use case of a linear servo motor.

PID loop control capability (up to 8 loops simultaneously) has been added to the CLICK® Series of stackable, Ethernet-capable micro brick PLCs.

Like most first-time projects, though, there were some lessons learned. The power supply needs a little work and the range of balance compliance didn’t meet expectations.

Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how to work with moving parts. In the end, you’ll have a real, physical thing that does ...
