You can use Arduino's C-like programming language, or Python, but we'll only use C in the examples below. In Arduino programs, called Sketches, you essentially write code to set up your Arduino ...

That means all you have to do is browse through the book, pick a tutorial you want to work on, gather the materials, and you're pretty much set. However, as you get comfortable with using Arduino ...

When building Arduino projects for beginners, you'll usually need both input and output sensors. However, you can come across some simple projects like the Blink example that only require an LED ...

Arduino is a popular open embedded hardware ... Then calculate the resistor value (R), in ohms, like this: R = (Vs – Vf)/If. For example, I have some of these 5mm red LEDs and a 9-volt power ...

Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed ...

Furthermore, one can forward data from the Arduino UNO to a URL via a “Webhook” that can be user-configured, too. An example is provided that shows how to use Arduino Cloud with webhooks to ...

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 ...

If the Arduino IDE isn’t your thing, you could always do it the cool way with [CNLohr]’s programming tutorial we featured last week.

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 ...
