I remember either Electronics Hobbyist or Electronic Experimenter's Handbook from the early 1980's featuring a light dimmer circuit named Dynadim. The circuit dims an incandescent light bulb with a preset delay using a slide potentiometer interfaced to a MOSFET ( dual-gate like a 40673?)...
I am using a MSP430 to switch a high powered LED. MSP430 output pin can source 5ma at 5V. I want to switch a 12V source to a LED that will be driving 5A and it will be switched like a strobe very quickly. I need some help with choosing the right transistor or MOSFET in order to accomplish...
