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 ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Arduino libraries, like libraries for other programming languages, help easily extend the range of functions available to users in the standard integrated development environment (IDE). They are ...

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino ...

We all like cheap items off eBay especially if they do cool and unusual things, sometimes we get so carried away by the price that we do not even realize that fact that we do not know anything about ...

If you've used Arduino technology, chances are that you've come across libraries written by Adafruit's Limor 'Ladyada' Fried for the many devices and sensors that the company has to offer. Writing ...

We've all missed the buzzer and forgotten a load of laundry once or twice. While setting an alarm is easy enough, but this Arduino-powered alert system will just send you a text when it's time to grab ...
