Arduino programming for 3 stop mini-elevator - Programming and wiring diagram

Closed - This job posting has been filled.

Job Description

I need an Arduino specialist to design and program a control system for a simple elevator (dumbwaiter) that has 3 stops. Each stop would have a 3 button array to direct the motor to deliver the carriage to the 1st, 2nd, or 3rd floor. I anticipate trip switches at each stop to turn signal motor shut off at the appropriate height as well as emergency trip switches at the bottom and top floors to ensure no damage can be done in the case of a basic operational failure.

Project outputs will include an arduino program (Arduino Uno), a complete wiring diagram and a complete materials list. I can provide motor specifications, run-length, and any other info requirements to the project lead.
