I had the idea to make some kind of alarm that would go off if anyone but me removed the wallet from my pocket. A quick google search revealed tons of wallet alarms, but I noticed that they all had a credit card form factor(that’s good) and would make noise when exposed to light(that’s bad). This represents a problem since the pickpockets in the videos tended not to open the wallets till later at another location. I needed something that would make noise as it was removed from my pocket. Most importantly, I needed the alarm to be locatedinside the wallet. This immediately makes the wallet undesirable and will hopefully make someone drop it like hot coals.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
