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 ...

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 ...

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 ...

The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...

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 ...
