The version 2.0 of the Arduino Load Driver enables you to use 5V to control up to 100V allowing you to supply power to a wide range of different peripherals including motors, solenoids or anything ...

watch the video below to learn more about the 3D printed sentry gun which is capable of monitoring a desired area and firing at any target that triggers its ultrasonic sensor.

The tutorial runs a bit fast, and you’ll probably want to check out Nedelkovski’s previous tutorials if you’re not sure how to connect your phone to the Arduino board over Bluetooth.

When it comes to learning about microcontrollers, everyone has to start somewhere. [Lady Ada] recently posted a tutorial on burning the Arduino bootloader to standalone chips for those just getting… ...

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 ...

This is a simple project. It uses an Android device to switch an LED driven by the Arduino. Connectivity is provided by the Bluetooth module inserted in the breadboard. But one look at the UI on th… ...
