Re: Controlling 100 LEDs?

Basically I want to be able to control about 16 or more electromagnets. To be able to turn them off and on from my PC. Each one is fairly small (dice sized) and doesn't require much current, although I will use an external power supply. Each electromagnet will keep a plate elevated or lowered depend...

Just out of curiosity what's the max number of pins I can extend to even with additional products?

Re: Controlling 100 LEDs?

What if I wanted to control something besides LEDs like an electromagnet? I looked at multiplexing and if I understood correctly only one row is on at a time. I need each component to stay on if they are supposed to be on at all times.

Controlling 100 LEDs?

I would like to be able to turn on and off 100 LEDs.
The problem is that there isn't enough pins to control each one.
How can I solve this?

Thanks in advance.
