In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board ... This voltage is used to drive the transistor that will switch ON the relay and the load (in our ...

We frequently get home automation tips, many of which have simple circuit ... with his in-the-wall servo-controlled light switch. This build forgoes the need of any relay to switch mains power ...

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 ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay ... but if you want total control over your system and something ...

Attached to the servo horn is a slotted cylinder sized appropriately to fit the shape of the control knob. An Arduino ... switch in the ‘on’ position and turning the unit on/off via a relay ...
