Check out this useful tutorial from bergerab on instructables on how to make your own backpack anti-theft alarm using arduino!
If you’re a student, like me, then you have heard of all the theft that occurs on campuses today. I can’t even leave my backpack alone for five minutes without worrying about it getting stolen. To ease my mind and to help fellow students, I’ve designed a backpack ant-theft alarm. When activated, this device senses when a backpack is picked up and sounds an alarm to draw attention to the thief. The alarm is perfect for quiet places such as libraries or classrooms where a buzzer would be heard clearly. It is a great project for beginners and experienced electronics hobbyists alike!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
