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 ...

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 ...

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 ...
