Hello,
To make a long story short I am wanting to use a switch (ON-OFF-ON) and two push buttons to control my motor. On the switch, each "ON" toggle with control the direction of the motor. When toggled "ON" it should travel continuously (in either counter clockwise or clockwise depending on which "ON" is toggled. The buttons will do the same (one controls clockwise step while the other controls counter-clockwise step) but instead of it stepping continuously it will only step once. I used help from here Stepper Motor with DRV8825 and Arduino Tutorial (4 Examples) to assist with my wiring setup.
My main question is, did I code this right? I understand that debouncing the buttons would be needed so I used this library GitHub - j-bellavance/EdgeDebounceLite: Just replace digitalRead() with debounce.pin() for help. I did not understand coding two buttons from the tutorials by Arduino.
Everything complied correctly so I am unsure of the real issue in the code as for I am a beginner.
