The code is very simple, here is mine, I am not sure if I used this exact code in the video, you might need to tinker with it.
int phase1 = 2;
int phase2 = 3;
int phase3 = 4;
int led = 12;
unsigned long stepLength = 40000;
int minStepLength = 1400;
int steps = 5;
void setup() {
pinMode(led, OUTPUT);
pinMode(phase1, OUTPUT);
pinMode(phase2, OUTPUT);
pinMode(phase3, OUTPUT);
digitalWrite(led, LOW);
}
void loop() {
switchStep(1);
switchStep(2);
switchStep(3);
if(stepLength > minStepLength)
{
stepLength = stepLength - steps;
} else {
// set the minimum pulse length
stepLength=minStepLength;
}
if (stepLength < 39950) {
digitalWrite(led, HIGH); // second gear
steps = 300;
}
if (stepLength < 20000) {
digitalWrite(led, LOW); // third gear
steps = 50;
}
if (stepLength < 3000) {
digitalWrite(led, HIGH); // fourth gear
steps = 2;
}
}
void switchStep(int stage)
{
switch(stage)
{
case 1:
digitalWrite(phase1, HIGH);
digitalWrite(phase2, LOW);
digitalWrite(phase3, LOW);
myDelay(stepLength);
break;
case 2:
digitalWrite(phase1, LOW);
digitalWrite(phase2, HIGH);
digitalWrite(phase3, LOW);
myDelay(stepLength);
break;
default:
digitalWrite(phase1, LOW);
digitalWrite(phase2, LOW);
digitalWrite(phase3, HIGH);
myDelay(stepLength);
break;
}
}
void myDelay(unsigned long p) {
if (p > 16380) {
delay (p/1000);
} else {
delayMicroseconds(p);
}
}
