In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Other features include : Autocomplete during sketch editing, Dark Mode, safe storage of Arduino sketches in the Cloud, Serial Plotter, and application updates and more. Arduino IDE 2.0 ...

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated p… ...

The Arduino team has announced that Arduino IDE 2.0 is available for download. The Beta version was launched back in Spring 2021, and now - following feedback received from the Arduino community - the ...

The relay can be used to open a door lock and if you need a louder alarm then you can replace the small buzzer with a high power siren. I will not talk about the RFID reader because you can find a lot ...

This module is modeled after an Etch A Sketch and combines Arduino and Processing sketches. With the help of Processing, you can trace a line using two controllers (potentiometers). One of the knobs ...
