Guys
Was wondering if someone could help me with a small project.
I'm after something that will allow me to control (open or close) an output based on an input voltage taken from a Gear Position sensor on a motorcycle (0v to 5v) i.e. neutal=0.5v, 1st=1.1v, 2nd=2v, 3rd=2.7v, 4th=3.5v, 5th=4.1v and 6th=4.7v)
Otherwards turn on when voltage is between 0V and 3V and off up to 5V.
(On for 1st, 2nd & 3rd and off on 4th, 5th and 6th)
I'm a bit rusty but something tells me I simply need a zener diode to allow a voltage connected to an operational amplifer?
Also, what if I wanted to switch the output on for 4th i.e. variable resistance?
