Are you tired of friends borrowing your books and never returning them? Maybe you’re sure you own 1984 but can’t seem to locate it? Do you find a strange satisfaction in using the supermarket self-checkout simply because of the barcode beep? With the ShelfChecker smart shelf from maker Annelynn described on Instructables, you can be your own librarian and never misplace your books again! Beep!
Annelynn built her smart shelf utilising a barcode scanner, LDR light sensors, a Raspberry Pi, plus a few other peripherals and some Python scripts. She has created a fully integrated library checkout system with accompanying NeoPixel location notification for your favourite books.

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.
