Aaron and Kelly: Working on Arduino

So we've been working hard at our coding for a while now, with mixed success. Our physical wiring and Arduino setup appears to be sound, with each switch and relay working when tested with simple code.

However, connecting everything to work in tandem the way we hope is not going quite as smoothly. Here is our code to date.

//Define the sensors

const int seat = 12;

const int fwdStop = 2;

const int revStop = 4;

//Interrupt sensor

int shiftStageTwo = 0;

//Define the motors

const int fwd = 7;

const int rev = 8;

//Define the stages in the process

int stageOne = 0;

int stageTwo = 0;

int stageThree = 0;

//Interrupt stuff

volatile int shiftStagetwo = fwdStop;

void setup() {

//Set pin modes

pinMode(seat, INPUT);

pinMode(fwdStop, INPUT);

pinMode(revStop, INPUT);

pinMode(fwd, OUTPUT);

pinMode(rev, OUTPUT);

//Set interrupts

attachInterrupt(stageTwo, swap, LOW);

}

//Interrupt function

void swap() {

if (shiftStagetwo == fwdStop) {

digitalWrite(fwd, HIGH);

digitalWrite(rev, HIGH);

}

else {

digitalWrite(fwd, HIGH);

digitalWrite(rev, HIGH);

}

}

void loop(){

stageOne = digitalRead(seat);

stageTwo = digitalRead(fwdStop);

stageThree = digitalRead(revStop);

if (stageOne == HIGH) {

//delay(5000); //delays don't work if multiple delays are present

digitalWrite(fwd, LOW);

digitalWrite(rev, HIGH);

}

else {

digitalWrite(fwd, HIGH);

digitalWrite(rev, HIGH);

}

if (stageTwo == LOW) {

digitalWrite(fwd, HIGH);

digitalWrite(rev, LOW);

}

else {

digitalWrite(fwd, HIGH);

digitalWrite(rev, HIGH);

}

// if (stageThree == LOW) {

// delay(5000);

// digitalWrite(fwd, HIGH);

// digitalWrite(rev, LOW);

// detachInterrupt(stageTwo);

// }

// else {

// digitalWrite(fwd, HIGH);

// digitalWrite(rev, HIGH);

// }

}

The interrupt function has effectively let us switch between motors, but things are still not quite up to par. Dominic's recommendation is to simplify our code and reduce most of our methods to if and while loops. That's next on our plate!
