We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

You can adjust the spinning speed with a potentiometer and you can also set a minimum and maximum speed in the code. You will need an Arduino board, a potentiometer (I have used a 50K one), as many ...

One thing the Arduino ecosystem is rarely praised for is its speed. That’s where [Playduino] comes in, with his video (embedded below) that promises to make everyone’s favourite ...

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

Arduino Uno + potentiometer + OLED == virtual circular dial. Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking ...

DIY Arduino High Speed Photography DSLR Trigger. 4:35 pm November 10, 2010 By Julian Horsey. Looking to get a little more creative with your photography and fancy giving high-speed photography a go?

I’ve always appreciated simulation tools. Sure, there’s no substitute for actually building a circuit but it sure is handy if you can fix a lot of easy problems before you start solderi… ...

In this case, the sensor detects the impact of the speed bag and sends a signal to the Arduino Uno. The signal from the sensor is transmitted via a PC817 optocoupler.

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed photography setup using one, instead of ...

The cnc lathe rev counter prototype now works - with a bit of help from friends who can actually programme. On a signal generator, the display is ...
