I want to use an arduino, either a mega or an UNO R3, to make both signals at the same time. I know a mechanical relay would not be capable of running the necessary frequencies (0 - 100khz-ish), so how would I do this? Transistors?Better use MOSFETs, they're more efficient in switching, faster, too. Provides more power if you need it, aswell.
Good luck on the project! Quite ambitious, but FUN! Post some pictures!
Would a mosfet like this work ? RadioShack.com Official Site - America's Technology Store
What would I do with each of the pins? I need a fritzing diagram!As for the project, take a look here
Wait that isn't an F20c - S2KI Honda S2000 Forums
The MOSFETs would be used for voltage isolation, protects the Arduino pin, too. In case of a higher voltage pulsing that is required to the system, the MOSFET would help.
On the fritzing diagram attached, your output to the system would be on the middle pin, and the battery pack could also be 12V.
