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 ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...

As we work on projects we’re frequently upgrading our tools. That basic soldering iron gives way to one with temperature control. The introductory 3D printer yields to one faster and more capable. One ...

Let’s rollback the hobby electronics calendar a few decades with [myvideoisonutube’s] alarm activation control circuit using a matrix style phone keypad. The circuit is quite old using CMOS 4081 with ...

Anyone looking to learn to code may be interested in a new Arduino-based learning tool called Educeeno, which is coming to the end of its Kickstarter crowdfunding campaign and has already successfully ...

Arduino has unveiled a new low-code solution for product creators designing hardware for the internet of things (IoT). It also unveiled a new family of Portenta chips for a variety of hardware ...

I wasn't aware of this one, though it launched in April: the self-explanatory Arduino AI Assistant (the AAA). There are three main, possible, development wins identified. One is to generate code more ...
