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 ...

Normal: Manual control of each relay All ON: Activate all relays All OFF: Deactivate all relays Alternating: Alternate between odd and even relays Sequential: Activate one relay at a time in sequence ...

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 ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

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 ...

Arduino enthusiasts and those interested in learning more about electronics and micro controllers may be interested to know that the official Arduino team has announced the first ever official Arduino ...
