#Arduino timer interrupt stepper motor code
Lastly, did you have something working after asking your other question? I suggest saving your broken code separately and returning back to what worked. Here's a simple example which stops a motor and here are the interrupts docs. a pin different than the one to turn it off). In addition, maybe you want to turn the motor back on? So just set up another ISR, maybe attachInterrupt(anotherButtonPin, anotherISR, RISING) which would call anotherISR when anotherButtonPin is held down (i.e. Then stop the motor until further notice. Turn off the flag so this runs just once. This runs when the button has been pressed. low to high).ĪttachInterrupt(buttonPin, myISR, RISING) I opted to run it on the rising edge (i.e. Set up the interrupt so that when the button is pressed, myISR function This will let you run a block of code only when an certain event occurs (i.e. I don't have my Arduino set up right now but I believe the attachInterrupt method would work. One thing I would change is to use an interrupt for the digital pin. Please help me to understand where I have gone wrong with this code. these must be called as often as possible to ensure smooth operation Stepper.moveTo(maxDistance) //move 2000 steps (gets close to the top) PinMode(opto_shoot,OUTPUT) // set the pin that controls the shoot function PinMode(buttonPin,INPUT) //set that the button is an input Int motorAccel = 80000 //steps/second/second to accelerateĪccelStepper stepper(1, motorStepPin, motorDirPin) Int motorSpeed = 9600 //maximum steps per second (about 3rps / at 16 microsteps) Int sensorValue=0 //variable to store the vaule coming from the photocell Int sensorPin=0 //select input pin for the photocell Int maxDistance=-12000 //intial distance for motor to move
#include Ĭonst int buttonPin=4 //number of the pushbutton pinĬonst int opto_shoot=2 // Pin that controls the shoot function In the code that follows the idea was to condense the main actions of the motor (to raise the platform up to the glass, take a picture, then to lower back down and repeat the process) by containing the majority of the actions within a single if statement so that the computer would have a better shot at reading it the way I intended. However, in an effort to simplify my code I have managed to get my motor to stop moving altogether. So I have tooled around a bit more with my stepper motor and my button sensor (I want to have the motor stop when the button is pressed which I have for the most part figured out).
