I would get a choke line filter before the microcontroller
What is a choke line filter, and why do I need that?
My power supply is regulated and has strong noise filters (capacitors) and a 14V Zener in front. A pretty robust design.
The regulator is designed for Automotive usage. Works great, I also turned on the engine while the micro controller was on, and not even a small hickup. Smooth power.
Do you have a good diagram/design for a solid state switching that will run off TTL. ??
I wanted to have control of these functions without using relays. I would hook up a STAMP (I like basic).
I am using Arduino
. By TTL do you mean 5V logic? Arduino works with 5V, and it is very easy to program.
Coding is done in Wiring, which is C (and C++..) but with lots of easy to use libraries and a simpler syntax. You will have no problems, guaranteed.
Take a look at my Stromputer Project - lot's of information I put there, and feel free to ask me. https://www.stromtrooper.com/techy-wo...650-mk-1b.html
My Stromputer is already running off the bike's battery, and I can do anything I can dream of with it, because it is a full computer with input, output running on 16Mhz (My first PC was running of 4Mhz..)
There are many relays that can be controlled by the 5V output. Easy, and allows you to control high currents with a low current micro controller.
Skies are the limit...
