I didn’t actually plan this project, but rather it found me. I was at the Scrap Exchange, a local reuse center, when I found a very nice looking scanner that you might find at a grocery store kiosk. It had been ripped from its connectors and had unlabeled wires hanging from it; a bit of hardware gore if such a thing exists. It was labelled on sale for $6.25, and a quick search revealed that it originally retailed at over $500. I thought a great use of this would be to keep near our pantry so that when we are out of a spice or snack, we could just scan the item and it would get posted to our shopping list. I figured I would try to reverse engineer it, and if all else fails, scrap it for the laser and motor. This is a longer post that goes through the entire process, so strap in!
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
