Everything went fine until I found that the button is missing!
So I edited the code and let the led blink itself….

Here are the ideas for final project!
The first idea is a smart lock that detects the keys via NFC, and reminds the user if they forgot them. It uses distance sensor to detect the status of the door (open? closed) and requires a speaker that plays the siren.
The second idea is a clock with a background light that changes like the lunar phase. It requires a bunch of LEDs (diffused?) and motors that can control the hands.
The third idea is from a prototype developed in the Affirming Artifacts. It is basically a torchlight controlled by a smartphone. It requires a Processing sketch on the phone and a Bluetooth adaptor that connects to the phone. It also requires batteries, some LEDs and a solid body (3D printing?).
