I am using a A4988 stepper motor driver. I want to use the RST PIN to disable the power output to the stepper if it is not in action.
To do this, you have to pull it down. So I wanted to use a pin of my ESP8266 to do this. Unfortunately It does not work. I pull the pin 13 down but there still seems to be a very low current or voltage what prevents the A4988 board to switch everything off.
If I remove the jumper cable for a short time the board switches to off and I also can put in the jumper cable and the board stays off.
What can I do to achieve this goal?
Do I have to use some resistor somewhere?
