This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

For a quick test, one part of the dual-potentiometer was used with the help of a simple code to operate an Arduino Uno as an analog threshold detector. Using a10mm green LED as the threshold indicator ...

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. ... Do not power the circuit and ...

A great place to start is using the Arduino. Skip to main ... how to use digital and analog inputs when building Arduino circuits, including controlling LEDs using pushbuttons and potentiometers.

I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.
