With this clever project from Tony DiCola you can overcome the confusion of having multiple remotes by combining them all into an Arduino powered universal remote. The remote is built using a number of common parts including a IR led and an IR receiver. The IR receiver is used to decode the signals from the original remotes so that they can be sent to your entertainment devices by the IR led on the universal remote. When set up, the universal remote can provide an interface between your various entertainment devices and your smartphone allowing you to control all of your devices from your smart phone.

Rather than breadboarding your circuitry why not check out our own ProtoShield for Arduino. The ProtoShield is an excellent tool to turn your temporary, breadboarded project into something more permanent. The shield fits directly onto an Arduino board and has a large general purpose area in the middle where you can solder on your own parts to create a durable, long lasting project! The ProtoShield is a high quality, corrosion resistant gold plated PCB and represents great value at only $3! For more information or to order visit the ProtoShield product page.
