So we decided to use the servo motors to make cars that could be controlled with a throttle, utilizing a potentiometer for stop and go. All of that would work off of one Arduino, mean while we created a topiary/stop-light-like

Schematics and more coming soon… Once it is emailed to me!

Well I intended for there to be a video…but, apparently I did not record the video right!

Here is the code for the portion that I worked on… The topiary street light!

boolean isStop;

unsigned int time;

unsigned int lastTimeRed;

unsigned int lastTimeLEDOn;

int lastLEDOn;

int pinArray[] = {0, 2, 3, 4};

int timeRand = 1000;
int timeRandRed = 1000;

void setup() {
isStop = false;
time = millis();
lastTimeRed = time;
lastLEDOn = 1;

lightLED(1);

for(int a = 1; a timeRand) {
isStop = true;
lightLED(2);
}
} else {
if((time-lastTimeLEDOn) > 1000) {
if(lastLEDOn == 2) {
Serial.print(1, DEC);
// Serial.print(“ONE “);
lightLED(3);
lastTimeRed = time;
//Serial.println(“red”);
} else if(lastLEDOn == 3 && (time-lastTimeLEDOn) > timeRandRed) {
lightLED(1);
Serial.print(2, DEC);
isStop = false;
lastTimeRed = time;
randomSeed(time);
timeRand = random(5000, 10000);
timeRandRed = random(3000, 7000);
//Serial.println(“GREEN!!”);
}
}
}
}

void lightLED(int color) {
int prevLED = color-1;
if(prevLED < 1) {
prevLED = 3;
}

lastLEDOn = color;
lastTimeLEDOn = millis();

digitalWrite(pinArray[color], HIGH);
digitalWrite(pinArray[prevLED], LOW);
//Serial.print(color, DEC);
//Serial.print(" prev ");
//Serial.println(prevLED, DEC);

}

.: Code :.

int motorPin = 10;
int potPin = 2;

void setup() {
pinMode(motorPin, OUTPUT);
Serial.begin(9600);
}

void loop() {
int val = analogRead(potPin);
val = map(val, 0, 1023, 0, 254);

Serial.println(val);

analogWrite(motorPin, val);
}

//put whatever in pin 10 and a pot in pin 2 and you should be able to control it with the pot, or whatever. let me know if you have questions.
