Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter for your control circuit. There are plenty of resources you can find [...]

In previous blog posts, I’ve described two ways to use an Arduino to interface with an off-the-shelf remote power sockets / switches. The first method uses transistors to simulate button presses. It involves some soldering and hacking the remote control unit. The second method uses an oscilloscope to sniff the signal sent by the remote [...]

Update: check my blog post here for an even better and simpler way to decode remote control signals Note: the RF transmitter used in this article is available for purchase in the shop page. In a previous post I described a way to use an Arduino to interface with remote controlled power sockets. The idea [...]

Update: check my blog post here for an even better and simpler way to decode remote control signals For a while I’ve been looking for a way to switch household power line (110V) devices. One of the simplest options is to use a relay that is connected to the power line. This is easy in [...]
