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 ...

The Uno Rev3, is a great beginner board as it's included in many starter kits. It's also complemented with a host of online resources that even without the official Projects Book from Arduino, you ...

You’ll also need some jumper cables to interface the different parts of your Arduino project with the breadboard. While ...

Connect the GND of the battery to the GND of arduino – common GND. If you are using a 5V relay instead of 12V relay, you only have to connect the arduino GND. I am using a 12V relay. So the coil ...

Arduino Relay Basics - How It Works and How to Use It. Posted: June 3, 2025 | Last updated: June 3, 2025. Hi, I'm Bill. I'm a software developer with a passion for making and electronics.

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They n… ...

A 3D-printed flying quadcopter drone. 3D printing and flying drones are among the two most popular activities for Arduino owners.Here we have a project that combines both activities into one ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

“We collaborated with Renesas and Espressif,” said Arduino CEO Fabio Violante. This partly obscured photo is the only one Arduino has allowed out so far “Designed for maximum compatibility, the Uno R4 ...
