I have a problem with floating pins. I need a LOW on an "Enable" pin right from the start, so I place a PULLDOWN resistor between my "Enable" pin and GND.
Later I need a HIGH on the "Enable" pin. Is that possible?
I want to control a stepper motor using a stepper driver. The stepper driver "step" pin is floating when powering on the Arduino and the motor start to vibrate for about one second. And I dont want it to do that.
The stepper driver has an "enable" pin that need to be HIGH to make the steppers work. So I want to have a LOW on the "enable" pin right from the start and maybe 2 seconds later have a HIGH.
Thanks in advance for your answers
