I used old dependable goody dispensing technology and ordered a wire Spiral spare part for a vending machine. After all, vending machines always deliver what was paid for! The one I ordered has a 3.25” diameter coil, and works well in 4” ABS pipes. Candy is fed from a 2-gallon Bucket bolted to a Toilet Flange, fed into a Sanitary T, with the Wire Spiral running in a pipe perpendicular to the bucket. I suggest using new parts and not salvaged ones.
The system is only allowed to rotate once by using a Plunger Activated Snap Action Switch. It’s a switch with a roller on it. If the roller is depressed the motor will keep running. When the switch hits a hole or divot the motor stops turning.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
