l hoping someone can write me a program for a car project I'm doing. Wanting to run all my electrics through my Arduino. Like head lights so parkers and main beam, wiper speed high and low,heater fan high and low, all going though relays.
hope someone can help
If the car is not too old, then it may be possible to interface directly to vehicle electronics via the CAN Bus. This may help you to specify your requirements less generally.
No its a old girl 6v6gt
Are the head lights electric or carbide lamp technology ?
It's a old car but lm wanting to use small momentary push button switches in the dash.
I was going to use the small arduino relays and control 30amp 12v relays.
Those things already go through relays. You're not running anything 'through' your Arduino except the signal for the relays, except you'll need a whole new set of relays because auto motive relays are 12v.
What will your interface be to control these things? What's the point of the Arduino if you're just replacing buttons with different buttons?
Because you for example head lights, you press the button once the packers come on then if you press it again the main beam comes on and when pressed again they switch off. Same as the wiper press once low speed through a relay and press again high speed etc
