This is a basic example of controlling a stepper motor using an Arduino. I’ve coded from scratch a function that allows the motor to ramp up (accelerate) and ramp down (decelerate) based on a specified rate. The code uses the basic Arduino Stepper.h library. While other libraries have acceleration built in, this might be useful to some.
This ramping example could be used to control virtually anything using a PWM output and a solid state relay. Temperature is a common application of controlled ramping.
- Ramping (acceleration) up and down
- Potentiometer to set speed
- Enable/disable button with debounce routine
- Limit switch input to detect the home position, end position and the locations where ramping up/down should begin
