I'm building a liquid dispensing/vending machine. Here are the features it'll have:

  • The machine will have a big touchscreen and user can interact with it and select her options. It should also have a capability to show animations/videos.

  • It'll have motors to control the flow of different fluids and dispense some liquids. It is controlling around 12-15 sensors, and 12-15 motors/relays, probably a camera.

  • Machine also needs to have a payment method integration.

  • Also, it should be connected to internet and receive commands from a smartphone app/web and send some sensor information to a common database.

Do you think a Raspberry Pi 3 running Android Things is an appropriate platform for this? Can all of the features above be implemented that way?

  • I think a raspberry pi would be perfect for that - I'm not sure about the Android part, though, but I think it's been done. – Benjamin Ashbaugh Jan 03 '19 at 18:14

    Do you know if I can get some references on how to build it. This would be my first raspberry project. – lumos42 Jan 03 '19 at 18:15
  • Do you know python? If not, learn that first. – Benjamin Ashbaugh Jan 03 '19 at 18:16
  • Welcome -- but we're actually not a discussion forum, and invitations to brainstorm widely are not appropriate to the format. Hence, I've edited your post to focus on a few objective questions. Please take the tour to understand better how the site works. – goldilocks Jan 03 '19 at 18:17
  • I have good experience with python and have developed web applications using django, flask. – lumos42 Jan 03 '19 at 18:18
  • @goldilocks - I apologize if this not an appropriate forum. Do you know of any internet forums where I could get some ideas/recommendations?

    The edited version looks better, Thanks!

  • The Pi Foundation has a discussion style forum: https://www.raspberrypi.org/forums/ – goldilocks Jan 03 '19 at 18:24
  • @user2485594 Just do some research with searches like "raspberry pi GPIO tutorial", "raspberry pi touchscreen tutorial", "rpi camera tutorial", etcetera. – Benjamin Ashbaugh Jan 05 '19 at 17:55
  • @user2485594 And its completely fine to ask questions here once you get started on your project - just make sure it's a specific question about one or more specific problems/etc, and make sure to do your own research first. – Benjamin Ashbaugh Jan 05 '19 at 17:57
