[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 ...

A:Hi Chris, and yes, you can diagnose this problem yourself. I have had a lot of questions on how to diagnose and repair cruise control for all different generations of the Corvette. Since you did not ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

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 ...

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 ...

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 ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

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 ...
