by J.B. Wylzan

Project 9:  Thinking Lights

This project is a game about logic. Player/s will guess which Led will turn on next.  The  setup will also be used to test your motorshield and dc motors as we start to design our robots.

4 LEDs
4 resistors 
connecting wires
Arduino R3 UNO board

  The Game of Logic: World of Guessing 
  This example code is public domain.

long randNumber;
int y = 1000;

void setup(){
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);

void loop() {
  randNumber = random(0, 5);      // print a random number from 0 to 4
   switch (randNumber) {
  case 1:    
    Serial.println("yellow led");
    digitalWrite(3, HIGH);   // turn the LED on
    digitalWrite(3, LOW);    // turn the LED off 
  case 2:    
    Serial.println("green led");
    digitalWrite(5, HIGH);   // turn the LED on
    digitalWrite(5, LOW);    // turn the LED off 
  case 3:    
    Serial.println("red led");
    digitalWrite(6, HIGH);   // turn the LED on
    digitalWrite(6, LOW);    // turn the LED off 
  case 4:    
    Serial.println("blue led");
    digitalWrite(9, HIGH);   // turn the LED on
    digitalWrite(9, LOW);    // turn the LED off 
}  // end of program

// Challenge: Write a sketch that will turn ON and OFF the Leds as shown in the table below:

L=Low ; H=High

Actual Layout:

1. Use the model as shown above
2. Run the Arduino Interface
3. Select File > New
4. Copy Code #9 above
5. Paste Code #9
6. Click File > Save
7. Click Verify
8. Click Upload
9. Leds will turn On and Off randomly.

Project # 10:  Railroad Traffic Lights
