Hello,
I'm building a micro controller controlled power module that will operate 64 individual power ports. This is to be used as a firework ignition sequencer. Each power port will ignite an electronic match, one at a time. There will not be more than one port on at a time. The power matrix is to be powered by its own battery supply and controlled through data lines by the micro controller. I've just started learning about mosfets and they seem to fit the bill. The provided schematic shows what I think to be a good start using 595 shift registers, p-channel and n-channel mosfets to control the current flow in the array. The problem is...I can't get it to work on my test array breadboard project. I'm missing something, maybe a lot. Can someone review the schematic and let me know if the principle is sound.
Thank you
