Hi guys, i was looking for some help from some more experienced people as im hopeless with electronics, im just gonna shout out what im aiming to do, hopefully someone will take the challenge to help me get my head around it (or at least point me in the right direction)
what i am trying to build is a relay controller with an LCD screen and LED's to show you whats activated and whats not...
it's for the dash of my race buggy/sand rail (an Edge Barracuda)
i need a large backlit LCD screen to display the status of a few things..
Door (reed switch)
Relay which is wired up to my modified Go-Pro Helmet camera to record all the carnage.
(maybe a engine temp sensor would be handy too)
so basically, i want five buttons on the dash, with status LED's just above them...so, when you turn the ignition on they're red, and that specific button is pressed, it turns green.
obviously when i press the lights button, i want them to stay on, and when i press the button again, it turns them off.
but when i press the starter button, it will only stay on for the same time that i'm pressing it.
the five buttons need to be...
Lights (push-on, push-off) 12v 240mA
Door Latch(momentary) 12v 400mA
Camera(push-on, push-off) 12v 350mA
Starter(momentary) 12v 240mA
Fans (push-on, push-off) 12v 240mA
thats about it, i have no idea where to even start, ANY help at all would be much appreciated, thanks.
