Current Dump

Hi,

Hope you can help, what Im wanting to do is dump around 3 - 5 Amps out to 4 DC coils in sequence when a ir sensor was obstructed in between each coil for around a 10th of a second each.

Worked out what im getting at yet?

The ciruit would have to run off a 9.6V 2000mAh battery..

Thanks for you time

Sounds like a rail gun. :twisted:
