Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. // Pin 13 has an LED connected on most Arduino boards.

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 tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule power for stable operation. But ...

Ever wanted to build your own tiny remote monitoring camera to keep track of who's sticking their hand in the cookie jar? The Internet of Things camera is an open-source camera build based on an ...

E-paper, often known as electronic paper, is a type of technology that imitates the look of ink on paper. Electronic paper displays differ from LCD panels in a way that they reflect rather than ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...
