Introduction: Pong With Arduino and Processing

Picture of Pong With Arduino and Processing

This is using an arduino with meters to control the paddles on processing.

This will be using serial ports to be read by processing sent by arduino.

Step 1: The Setup

Picture of The Setup

Materials:

  • Arduino
  • BreadBoard
  • Jump Wires
  • Potentiameter
  • Processing
  • Arduino IDE

Step 2: Coding Arduino IDE

The Code

int firstSensor = 0; // first analog sensor
int secondSensor = 0; // second analog sensor

int thirdSensor = 0; // digital sensor

int inByte = 0; // incoming serial byte

void setup() { // start serial port at 9600 bps:

Serial.begin(9600);

while (!Serial) { ;// wait for serial port to connect. Needed for Leonardo only

}

pinMode(1, INPUT); // digital sensor is on digital pin 1

pinMode(2,INPUT);

establishContact(); // send a byte to establish contact until receiver // responds

}

void loop() { // if we get a valid byte, read analog ins: if (Serial.available() > 0) { // get incoming byte: inByte = Serial.read(); // read first analog input, divide by 4 to make the range 0-255: // firstSensor = analogRead(1)/4; // // delay 10ms to let the ADC recover: // delay(10); // // read second analog input, divide by 4 to make the range 0-255: // secondSensor = analogRead(2)/4; // // // send sensor values: // Serial.write(firstSensor); // Serial.write(secondSensor);

}

firstSensor = analogRead(1)/4;

// delay 10ms to let the ADC recover:

delay(10); // read second analog input, divide by 4 to make the range 0-255:

secondSensor = analogRead(2)/4;

// send sensor values:

Serial.write(firstSensor);

Serial.write(secondSensor);

}

void establishContact() {

while (Serial.available() <= 0) {

Serial.print('A'); // send a capital A

delay(300);

}

}

Step 3: Code for Processing

// If we have 3 bytes: if (serialCount > 1 ) {
