Low Rds, Logic Level N-channel MOSFET: A0I514 or AOI510.http://www.digikey.com/product-search/en?keywords=aoi514http://www.digikey.com/product-detail/en/AOI510/785-1487-1-ND/3603498Power dissipated in the part = I^2 * R = .6A * .6A * .0119ohm (AOI514 with Vgs = 4.5V) = 4mW, nice & cool.
- If i want to get 4 strips, i simply use a shift register 74hc595 to get more PWM outputs.
And where do i put a potentiometer if i want to control the brightness? And for color mixing what can i do?
No. PWM doesn't work through a shift register. (At least not easily...)
