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 ...

Welcome! This is my solution for using the millis function to create a clock. Keep in mind that the oscillator of the arduino is not very preciced. I recommend to use a real-time-clock if you got the ...

This is the basic example. It uses the serial monitor and no extra hardware is required. Three different software timers with millis are used to send something to the serial monitor. An example to ...

I have a Small Model Railway, 15 buildings, all with 1 LED, some with 2. All connected with an Arduino Nano and a TLC5974 24 channel PWM controller. I used PWM so I could set the desired brightness, ...
