The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

We wondered recently about those crude ASCII schematics you see in some documentation — are there any dedicated schematic-focused tools to draw them, or are they just hand-crafted using vario… ...

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

As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...
