Hello folks, I am in need of some help with a project I am attempting to make. The application is for automotive use with a small motor that opens/closes a valve within the intake assembly based on the position of a throttle position sensor.
The TPS (throttle position sensor) is a potentiometer that has 3 pins. 1) ground, 2) TPS output, 3) TPS power (5v).
The additional component I need to add to this part of the circuit is the intake valve motor assembly which has a small 2 wire motor, a second piece with a sensor that basically times the revolutions of the motor for the valve opening/closing. This is from a different vehicle and swapping out an entire ECU is not an option. This piece is a 4 pin plug (I have to pull pin data yet).
What I am attempting to do here is to feed the signal from my TPS to the valve motor so that when the output signal increases (throttle open) it opens the secondary valves, and when throttle begins to close it closes the secondary valves.
I talked a bit with some co-workers and they made mention that I could set up a set of relays to switch the direction of the motor as needed, but it needs to stop once the valve is opened completely, and also when closed. At this point they believe this will involve some type of microprocessor to be programmed it to work. I am not very skilled with this type of stuff and I am diving into something new for me here with this type of circuit stuff.
Any help/input is greatly appreciated.
