I am trying to use a DC Motor Driver (Cytron MD13S) to control an actuator and also sense the current as it is activated.
The reason for the current sensor is to perform a reverse polarity when a certain threshold has been reached. The current sensor I will be using is the INA219.
The issue is I have to control multiple actuator at once. I am pretty sure a single channel DC Motor Driver can energize say 2 or more actuator at once.
However, I would like to have current readings of each individual actuator when it is energized so that I can perform certain logic when any of the reading hit a threshold. I am unsure if this can be done.
I have drawn a simple diagram of what I think may work and would like to seek you experts for opinions and suggestions.
This is my first idea of separating the connection of the current sensor to the motor driver. I'm not sure if it'll affect the current readings.
The second idea is to merge both positive and negative wires together and to the motor driver.
Will any of these setup work?
