Have you ever wished there was a better way to be notified when your laundry was done? Have you ever forgotten a load in the washer because you couldn't hear the buzzer and your clothes became smelly and moldy from sitting there for too long? Well, I have and decided to solve this problem by building this simple notification system using an Arudino microcontroller. It uses a dual-axis accelerometer to detect motion and vibration coming from the washer (or dryer) and alerts my phone via SMS text message when the machine is no longer vibrating. I tried to build the easiest system I could using parts sourced from a local store and some online tools that help simplify the process of sending these alerts. Follow along as I show you how to put together this simple but useful project.
As I mentioned in the intro, I bought everything from my local Radio Shack, but you can find all of these parts at many other places. Most of the parts below that do not have a link were taken from a microcontroller pack I had (http://www.radioshack.com/make-ultimate-microcontroller-pack-w-arduino-kit/2770077.html), but these can be sourced from anywhere.
