Controlling Halloween decorations with an Arduino Uno, an Ethernet Shield, and a Relay Shield.

We had a few Halloween decorations with push button switches that we networked via an Arduino Uno. Three of the relays from the relay shield were used to activate a Grim Reaper and two sets of skulls. The push button from each decoration was cut and discarded. One of the wires coming from a decoration was connected to the common and the other to the normally open contact of a relay. The Arduino sketch delivers a web based interface and parses incoming requests to evaluate which relay should Read more [...]

An Arduino-based networked rover

The purpose of this project was to create an internet-based rover using the combination of a cheap RC vehicle, an Arduino Uno with a Seeed Relay Shield, a Samsung Galaxy S3 in host mode, a workstation and PlayStation 3 controller. Our server software will run in the background on the S3 and visual feedback will be provided by the IP Webcam app available on Google Play. The client software will run on the workstation and send the status of the PlayStation 3 controller to the S3. The S3 will in Read more [...]
