Hi there,
Im new on here. I have a circuit id like to make up for a project i have on. Im after some help or pointers please.
I fitted a megajolt electronic ignition system to my car. It has 5 outputs that can be used as shift lights which light up at a programmed RPM. The LED`s must have constant +ve voltage, when a certain RPM is achieved the megajolt unit grounds that LED out so it is in circuit.
Now this works sequentially so as rpm1 is reached you get a light, as rpm2 is reached you get a second light, rpm3 for third light and so on.
Im after a circuit that switches off all the previous rpm lights as the new rpm is achieved. So as rpm2 is reached rpm1 switches off, as rpm3 is reached rpm2 switches off. ie only one led on at any time.
I think this is possible with relays, but im not keen on using them due to current and moving parts.
Any help would be brilliant.
Thanks
