If your memory of slot cars as a childhood toy is of lightweight controllers with wire-wound rheostats inside, then you’re many years behind the state of the art when it comes to competitive slot car ...

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 ...

Arduino’s Modulino Hub, Extender, and Motors simplify I2C expansion, long-cable communication, and protected motor control ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

I have a friend (stop laughing -- it’s true -- I’m not going to proceed unless you get yourself under control -- thank you). We will call my friend Guido Bonelli (because that’s his name). Guido has ...

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 ...

Looking to get a little more creative with your photography and fancy giving high-speed photography a go? Why not create your very own high-speed camera trigger using an Arduino, piezoelectric sensor ...
