Stepper Motor With Push Button

[cwtulcar]

I am looking to use a stepper motor for a compression tester, can anyone tell me how I would wire a push button to control the downward and upward motion of the stepper with push buttons for each direction, preferably without a breadboard as I want to connect it directly to my adafruit stepper motor hat?

preferably without a breadboard

That could be difficult. The obvious method would be to use some intelligent device to read the buttons and control the stepper motor driver to move the correct direction.

If you are talking about the Pi Hat then it is designed to take I2C bus commands to work. If you want a simple switch control (I assume you mean something like while pressing a switch the motor moves, let go and it stops, and another switch to pick direction?) you might look into something like the Adafruit TMC2209 Stepper Motor Driver Breakout Board and maybe the Adafruit 555 PWM Output STEMMA - 1.5K~25 KHz or 1.5~250 Hz - STEMMA JST PH 2mm plus of course a couple switches.

My thought on how this would work is the TMC2209 controller only needs an input for direction (one of your switches) and then an input to the STEP pin where each pulse moves the motor one microstep. That input can come from the 555 timer board which since it doesn't have an enable pin, just let it run, and your other switch can simply connector or disconnect the 555 output to the STEP pin. And on the 555 board, between the switch and the potentiometer, you can set the motor speed.
