My switch project continues my last light bag project. I added a snap to the new bag, so when the bag is open, the light will on.
The Arduino part is not difficult. But I spent a lot of time on making the bag looks nicer. I made a small seat for the Arduino and I hide all the electronic things inside the bag.
There are multiple ways to wear it. The inside LED not only alert you if the bag is not closed, but also helps users to look for things inside easily.
