I'm new to Ardunio. The project I'm working on is such that I need to activate up to 30 low voltage (6V/12V) solenoids. From what I know there are not enough output pins to pull 30 relays high to trigger the relays. Can someone give me some direction to get me started?
How much current is needed? I offer a board with 32 N-channel MOSFETs to sink an Amp each to activate coils/relays/solenoids.
Shift in 4 bytes of data to select which are on or off.

1.2A at 6V, according to the description on eBay. 600mA at 12V. Will your board handle that current? Doesn’t seem very heavy.
I was planning two power supplies and fuse each for like 500mA with a slow blow fuses. Guess the 5v side doesn't need much. Could bury a GFI in there somewhere - make it look more official.
