I need to power an actuator that requires 12 volts and consumes between 5 and 10 amperes depending on the weight it is charging. Therefore I bought a power supply of 12 volts and 10 amperes.
My intention is to send in the arduino output the 12 volts and the current provided by the power supply.
The options that I have thought are the following:
a) Connect the power supply to the arduino input pins and send the voltage and current from the power supply to the actuator through the arduino output (I know I could do it directly to the actuator, but I am interested in doing it through of arduino since it will involve programming code to put conditionals)
My doubt with this option is if I do not damage the arduino by connecting that power source with that amperage. If there is no problem, my question is if I could handle the current of the power supply at the output or the current could only be handled by what arduino gives that would not be much.
b) The other option that I think is simply to send a flag to the output and then this flag activates the power supply in some way and then I could use the 12 volts and the 10 amperes to connect them to the actuator.
I would like you to guide me on the alternatives I have thought about and tell me what would be the right thing to do, or if you know some other way in which you should do it.
Thank you very much in advance Cheers
