Hi there:
I would like to show you my project.
I´m planning to control a solenoid (actuator) with an arduino board (5V).
There are two versions: one of them it’s for 24V coils and the other one for 6V coils. Both coils are low power consumption (<500ma) and works in 1s-ON, 60s-OFF intervals.
I need a h-bridge because actuator permits forward and reverse motion.
The question is related to the power supply. I would like to use a single 5V power supply in order to make a not very bulky project box.
What do you think about? Is it possible to “mix” different power circuits or groundings this way?
Am I missing something important?
Any other ideas?
Thanks for reading
Best regards
PS: Sorry, power supply in the drawings is 9V, not 5V (due to the arduino voltage regulator) and power consumption of the second circuit
