Control of 25 electromagnets Answered

Hello Everyone, I'm looking for a controller to manage 25 electromagnets. I've managed to come up with a driver circuit to energise each individual electromagnet using an N channel eMOSFET in parrallel with a diode. I need a programmable controller to operate the gate of each eMOSFET but the controller must be capable of managing all 25 switches. thanks for any suggestions in advance.

Multiplexing comes to mind, like used for these LED cube projects.
In binary you would only need 4 bytes to contrl up to 32 outputs.
Or you can use something like an Arduino mega to control them directly.
