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 ...

Basic Arduino kiln controller using Adafruit's MAX31855 thermocouple amplifier board and library (you need to get their library from them). Power switching using solid state relay. Change the ramp ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

Patrick Thomas Mitchell has been once again been creating awesome add-ons for your Arduino projects and has this month launched a new Kickstarter campaign for his Arduino speech recognition and relay ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
