I was lying in bed sick over the weekend, contentedly watching old Firefly episodes, when something horrible happened. I remembered that I had a load of clothes in the dryer and I was going to have to get up, walk across my apartment like a caveman and use my own eyeballs to check if the dryer was done. After that ordeal I vowed to come up with a way to make sure I never had to go through that again. Fortunately Kookye recently sent us their Raspberry Pi IoT Starter Kit which has all sorts of easy-to-use sensors along with example code to get started. If you are interested in smart home projects make sure to check out the review we did of this kit a while back.
I was sure that something in there would let me check on the dryer without getting off the couch. I noticed that the kit included a vibration sensor and, because my dryer is old and shaky, I decided that would do nicely. My plan was to attach the vibration sensor to the side of the dryer and have the Pi host a website that I could look at on my phone to check whether the dryer was done. Before we get started here is a screenshot of the final result:
