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 (RPM). You don’t need much… ...

After waiting almost a month, I opened up the OLED and went right to testing it out. The link in the description pointed me to this website, which is a tutorial from Adafruit. Apparently, Adafruit ...

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 ...

Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

The best of the suggestions in the Twitter thread brings us to the Arduino Entropy Library, which uses jitter in the microcontroller clock to generate truly random numbers that can be used as seeds.

Instructables user MakerBee's alert system uses an Arduino microcontroller and a dual-axis accelerometer. When your washer and dryer stop vibrating, the machine will know and alert you accordingly.
