Currently working on a project but having some trouble with one section of it. What I need to happen is on power up the arduino checks to see if their is any force on a force sensor if their is not it turns the stepper motor until it detects force at which point it should turn the opposite way a set…

Managed to work out a solution there's still some discrepancies in the code but all in all does what I need thanks to everyone for their advice! Im attaching the code incase anyone needs it for anything similar its not perfect but it works //Defines Control Pins: const int Button = 5; //pi…

[image] skylord711: value = analogRead(ForceSensor); //Read and save analog value from potentiometer int digitalVal= digitalRead(ForceSensor); Does your force sensor have analog and digital output? Are you aware you never use digitalVal? Are you also aware the three local vari…

[image] skylord711: void homing () { value = analogRead(ForceSensor); //Read and save analog value from potentiometer int digitalVal= digitalRead(ForceSensor); digitalWrite(dirPinX,HIGH); // Enables the motor to move in a particular direction by switching between HIGH and L…

From what I can tell the force sensor does have both digital and analog outputs I didnt notice that I never actually used digitalVal its left over from when I was messing around getting the motor to change speed based on the force so ill be sure to remove that thanks Not quite sure what you meant …

Ah okay didnt know that I had to update the value in the while loop thanks ill give that a shot!

@skylord711 Are you using arduino Mega? or..... If you are using arduino mega the pin A0 and 54 is the same. and so......... . Look image. have defined this pins twice... // defines Motor pins #define stepPin 54 #define dirPin 55 const int dirPinX = 55; // this will pretty much be dictating rot…

I am using a mega the comment says A0 but I changed that to A4

I gave that a go and it didnt work not sure if I did it right void homing () { start: int digitalVal= digitalRead(ForceSensor); digitalWrite(dirPinX,HIGH); // Enables the motor to move in a particular direction by switching between HIGH and Low // Makes 200 pulses for making one ful…

Hey thanks for the advice ive managed to work out a solution ill look at that link though and see if i can make any improvement thanks!

From reading your code it is unclear what you want to happen.

After it gets out of the while loop, value won't be <100 anymore and your goto won't do anything.

Maybe take a look at:

...and break homing() up into homeTowardsACertainForce() and backOffFromCertainForce().
