Stepper motor project

josefc1991 · April 27, 2024, 6:43am

Hello everybody, I am doing a project for a stepper motor that involves moving 288 degrees without using a limit or hall effect switch and the double bouncing feature for my cw button.... to make the motor scan till undouble bounced again. I have tried using
const int numberOfSteps = 200 * 0.80 to get me 288 degrees before the setup. Then input that into my loop for the void actONButtons but that was no success. Since I believe my dilemma is that the IF is reading so fast before the
FOR (int x = 0; x < numberOfSteps; n++)?
EXAMPLE:
if (buttonCWpressed == true) {
digitalWrite(directionPin, LOW);
digitalWrite(enablePin, LOW);
for(int n = 0; n < numberOfSteps; n++){
Serial.println("CW ACT ON BUTTON");
singleStep();
}

So far i have gotten most of what i need done expect for the limitation of the 270 degrees and the double bounce feature. I have tried the examples and googled my double bounce but looking for examples that involves stepper motors. Any information to steer me in the right track would help. Im also open to criticism within my code I believe it is overwhelming for what it needs to do.

im not a veteran with arduino im a novice in class trying to gain a better fundamental of c++/arduino. thank you

288 from where? If you want 288 from 0, then you must "home" your motor position. That usually involves an encoder - as simple as a limit switch or hall sensor.

"De-bounce" - Check MobaTools example sketches. I am not certain, but it has a lot of timing utilities. @MicroBahner

josefc1991 · April 27, 2024, 6:02pm

Are you talking millis? For the debounce? I found a couple last night that imma try out later today. And i wasnt homing it to begin with using robin 2 sketch 1 it would rotate the full 360. But i used the 200 x 0.75 somethint along the lines to get my 288. Where ever the stepper was at was its home...i was just looking for a general idea of how that sketch worked. Seems like the hall is a much easier option that settint an eternal code to limits the stepper angles.

Here is an example of debouncing a button...

read the button
has the button changed states (HIGH to LOW or LOW to HIGH)
if yes, start a timer...
... and store the new button state
if the timer has exceeded my chosen timeout (50 ms for me)...
... check if the button STATE is in the NOT PRESSED state, and the button (not state) is the PRESSED (LOW)
end of debounce, call a function

MicroBahner · April 27, 2024, 8:38pm

Yes it has . And can check buttons for short press, long press, single click, double click ...

whats up everyone had some downtime at work to mess with my stepper motor project. For the life of me I am lost on how to make the enable for the stepper to become unlatched if pressing the ccw button. EXAMPLE: I press the clockwise button till it hits the hall effect....halll effect turns the enable pin high causing the motor to stop...cool.....with that being said, when i press the ccw button it should unlatch the enable bit and go ccw and repeat etc etc....I been pounding my head on this for a bit and was looking for guidance on this. Yes i know i have not messed with the double bounce feature yet haha. One step at a time...thank you again everyone for your help and opinion.
