Hi all,
I've signed up, as I am trying to find a solution to a 12v automotive problem.
I have been asked to somehow convert the signals sent from the radio controls on the steering wheel, to seperate realy outputs.
The circuit is something like this:
--------[resistor]-------------[resistor]------------------- Output
| | |
| | |
Switch1 Switch2 Switch3
| | |
| | |
------------------------------------------------------------- -ve
There are 3 switches, which all share a common earth.
There's then resistors between the switches, to change the Output resistance, depending on which switch is pressed. (Sorry if i'm teching you to suck eggs!)
Anyway, I wish to gain 3 seperate outputs, either -ve or +ve (doesn't matter), to operate 3 seperate relays.
Again, the circuit is to be used in a 12v car.
Does anyone know how this can be done?
Cheers,
Stu
