I am looking for a drive to control 8 (or more) devices (120V).
It is for an art project. We have 3 air pump, 3 lights, and 2 fans.
I need those devices to run at same time but different period.
Step 1: electricity go through 1st device for 3s, 2nd device for 5s , and 3 other devices stay at rest.
Step 2: electricity go through 4th device for 7s, 2nd device for 2s , and 3 other devices stay at rest.
Step 3....step 4......v.v.
I don't know anything about robotic. I have tried to contact a lot of companies that supply micro-controllers, but most of them do not have any controller for 120V or they can only control 4 devices the most.
I really need to know what type of drive I need so that I can order.
Thank you very much
P/s: It's for an art project.
