I have a DC motor that is currently connected to a circuit that allows for the circuit to be reversed. The motor is connected to a toggle switch that performs two functions:
1. Breaks the current to the motor
2. Reverses the direction of the motor
The operation occurs in the following:
1. A light switch wall timer is triggered ON
2. DC motor begins to run in the direction dictated by the switch.
3. Motor continues to run until the toggle switch is flipped.
4. The light switch wall timer is triggered OFF
...Repeat steps 1-4
The act of the power to the DC Motor circuit board 'resets' the motor and allows it to again run. The position of the toggle switch determines the direction the motor will run.
WHAT I NEED:
The mechanical function of the switch is causing issues as it is not adaquately translating to the desired travel of the door to which the motor is connected. I would like to change out the mechanical switch with an electronic one that would register when the door is in full OPEN or full CLOSED position, send the signal to the motor circuit board to stop movement AND reverse direction of the motor for when the Power cycles via the light switch wall timer.
WHAT I THINK:
I believe I need an H bridge chip along with two Reed switches.
What I cannot figure out, is, how do I maintain the current flow state to the motor while the door is in transition?
I think this is a simple problem, but it is elluding me.
