I’m an absolute beginner and I believe I have started a project which is beyond me and I really need some help!
I’m working on a project involving 70 small 5 volt motors.
I need each motor to turn in one direction for a certain amount of time, and then in the other direction for the same amount of time… and then back again in a constant loop and never ending loop.
The time of the changeover should be different for each motor and pre-programmable. The times vary between 20 seconds and 10 minutes.
Each motor is so far apart from one another that controlling them with one Arduino or Raspberry Pi would be impossible – And buying an Arduino per motor would be too expensive.
What would a cheap, effective and reliable system (which I could build myself) be? I was thinking transistors and a relay – adding the transistors to make the delay larger. But I think this is a bad idea - and anyway, I have no idea how I could make that work. Any ideas or suggestions would be extremely helpful!
---
Another problem is that I want to control the speed with which the motors turn. That is a secondary problem – but if you know of answer that could solve both problems in one that would be amazing!
Thanks in advance!!!
