Free Arduino Kit Contest! Comment (constructively) and we will enter you in our "Win a free DIY Arduino Kit" Contest!
One of the fun things to do with an Arduino is to make your appliances smarter. From better instrumentation, to giving the appliance the ability to make decisions based on sensor input, to centralized or remote monitoring (Smartphones, etc.) and data logging, your fridge, microwave, stove, HVAC, home alarm system, etc., is ready to be Arduino-ized.
Anyone can buy an Arduino board ($30-$60 or so) and stack shields on it, but sometimes building the Arduino and the project on a single board is preferable. We will show you how to prototype a complete project on a solderless breadboard, and then move it to a protoboard for posterity.
We will be using a 840 tie point solderless breadboard, and a matching protoboard. This way all the tie points are labeled the same, and the physical layout is the same, making the transitional painless.
