I am working on Arduino Mega 2560 which is controlling four steppers with BT6560 Driver, six pushbuttons and four limitswitches.
I want to code Arduino such that when I press RESET button (not talking about RESET button on Arduino), Arduino should run the code again from beginning.
And when I press RESUME button, Arduino should run the code from the moment I pressed the RESET button (like any song is resumed).
How can I be able to do this?
Below is a code I am working on:
int dirH_T1 = 3;
int steppin_T1 = 4;
int dirpin_F1 = 5;
int dirH_F1 = 6;
int steppin_F1 = 7;
int dirpin_T2 = 8;
int dirH_T2 = 9;
int steppin_T2 =10;
int dirpin_F2 = 11;
int dirH_F2 = 12;
int steppin_F2 =13;
int PB17ACW=23;
int PB17ACCW=22;
int PB17BCW=25;
int PB17BCCW=24;
int S01 = 34; // SENSOR INPUTS
int S02 = 35;
int S03 = 36;
int S04 = 37;
void setup()
{
pinMode(dirpin_T1, OUTPUT);

pinMode(dirH_F2 , OUTPUT);
pinMode(steppin_F2, OUTPUT);
pinMode(PB17ACW,INPUT_PULLUP);
pinMode(PB17ACCW,INPUT_PULLUP);
pinMode(PB17BCW,INPUT_PULLUP);
pinMode(PB17BCCW,INPUT_PULLUP);
pinMode(S01,INPUT);
pinMode(S02,INPUT);
pinMode(S03,INPUT);
pinMode(S04,INPUT);
}
