Wireless communication between two Arduinos using inexpensive RF modules
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless...

Simple Infrared Barrier
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places...
