Sunrise Alarm Clock 3

LED Dawn / Sunrise Alarm Clock, Nightlight & Security Light – Arduino Compatible

As the nights gradually lengthened in autumn 2011, I discovered the joys of Arduino and thought that it would be a great way to implement something that I have wanted for a long while – a gentle way to wake up on a winter’s morning.  Sadly, it has taken me over a year to find …

Automation Sensors

Security / Automation Sensors using Arduino

Security system sensors such as motion detectors, reed switches, pressure mats, glass-break detectors, infra-red beams, and conductive film can be very handy for all sorts of things including home automation systems, interactive art installations – and sometimes even security systems! Almost all security system sensors provide a simple switched output that changes state based on …

Cat Repelling PIR motion sensor (covert) speaker box alarm using Arduino

This is a PIR motion sensor device that works with the arduino uno. In order to make it covert enough to be placed in multiple settings and portable enough to fit most places, I decided to make the case for it appear as a speaker. The inspiration for this project: My cat is a jerk. One of his …
