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

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 ...

The potentiometers were particularly frustrating. ... There’s really no point to this other than I wanted something that would work out the analog circuit simulation as well as the Arduino.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

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.
