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 ...

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 ...

Microcontrollers like Arduino are designed to control small loads, such as LEDs or sensors, directly from their output pins. However, these pins can only supply a limited amount of current (typically ...

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 ...

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 ...

To drive a relay from the Pi, one needs to cobble up a fairly simple circuit where the 3.3V GPIO pin turns on a transistor that drives the relay. This is such a common requirement that I figured ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing ...
