Update time.
the chip came in the mail. I went out and purchased a small breadboard for it. I will be doing a simple voltage divider calculation to get the data out of the water temp probe. I know it's most accurate when the resistant's are similar to each other so I will be using a 20 ohm...
Okay sweet. I might stick with the 328 just because I’m more familiar with arduino, I’ll definitely look into some voltage protection, I will still just be running those little relays to power he main relay. How does the board handle the 12 volts in from the alternator light?
I just did a quick search, can you really program that little chip in arduino IDE? How does it handle 12 volts? Hell I had no idea you could do that, I might just make my own circuit board too!
Holy crap how did you do that? I'm only using an arduino because it's the only board I know how to program, would love to make something simple like this.
yeah for the power supply I've simply ordered a 12v to USB wire that I will be connecting to the ignition fuse, it will simply power on with the key, run once, then nothing until the key goes on again. As for the relay, it is just powering the ford starter relay I've been using to run the plugs...
Codes getting there, I'm only going to be glowing for 15 seconds, then a 2 second delay that way I don't burn out the plugs. How long do you guys glow for temperatures below freezing? I was thinking 45 seconds for -15C and below.
1) Yes I plan on reading the ohms off the head water sensor and it’ll just go off a table of times.
2) I'm not sure how I'm going to run the 6 volt system yet, I need to find the wiring schematic for the superglow system that way I can 'reverse engineer' it. I may also just get 12 volt plugs.
3)...
So my super glow plug system has rusted away to the point of not working, I've been using a ford starter relay and a push button for the past year, but it's annoying explaining how to start my truck to everyone, so I've thought up a way to make my own using an arduino uno board, a relay board...
