I have four 12VDC electromagnetic coils and I need a circuit to turn them on and off in a sequence automatically, one after the other.
When I reaches the end, it reverses to go back down to the first solenoid the same way. is there something that will do this?

Hi,

Thank you for contacting RobotShop.
A solution to do this might be to use a 12V relay connected to each coil interfaced with a microcontroller to trigger each relay as you described.
You can for example use an Arduino UNO board (as the microcontroller) with this Relay Shield (it has 4 relays, one for each coil).

Regards,
