Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a ...

[Jesse Merritt] bought a manual speed controller for his router. It’s used in the CNC mill he build and he figured, why not add the ability for the computer to control the speed. The speed controller ...

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

This circuit is not the very latest in robotics, but it may be of interest to those of you involved in making little robots using popular and inexpensive components. The proposed idea is a ...

This could be an interesting one if you work with robotics, flagged by the Arduino team - a look at how to smooth the operation of a servo, to avoid jerking between positions. It's from the YouTuber ...

Maker and developer Rolf Hut has created an awesome Arduino powered longboard which is equipped with LEDs that react to the speed of the rider and board. Hut has used 4 x magnets and a Hall effect ...
