An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options.

This tutorial shows you how to use switch to turn on one of several different LEDs based on a byte of data received serially. The sketch listens for serial input, and turns on a different LED for the characters a, b, c, d, or e.

Hardware Required
Arduino Board

5 LEDs

5 220 ohm resistors

hook-up wires

breadboard

Circuit
Five LEDs are attached to digital pins 2, 3, 4, 5, and 6 in series through 220 ohm resistors.

To make this sketch work, your board must be connected to your computer. In the Arduino IDE open the serial monitor and send the characters a, b, c, d, or e to lit up the corresponding LED, or anything else to switch them off.

Switch statement with serial input

Demonstrates the use of a switch statement. The switch statement allows you

to choose from among a set of discrete values of a variable. It's like a

series of if statements.

To see this sketch in action, open the Serial monitor and send any character.

The characters a, b, c, d, and e, will turn on LEDs. Any other character will

turn the LEDs off.

The circuit:

void setup() {

// initialize serial communication:

Serial.begin(9600);

// initialize the LED pins:

for (int thisPin = 2; thisPin < 7; thisPin++) {

pinMode(thisPin, OUTPUT);

}
}

void loop() {

// read the sensor:

if (Serial.available() > 0) {

int inByte = Serial.read();

// do something different depending on the character received.

// The switch statement expects single number values for each case; in this

// example, though, you're using single quotes to tell the controller to get

// the ASCII value for the character. For example 'a' = 97, 'b' = 98,

// and so forth:

switch (inByte) {

case 'a':

digitalWrite(2, HIGH);

break;

case 'b':

digitalWrite(3, HIGH);

break;

case 'c':

digitalWrite(4, HIGH);

break;

case 'd':

digitalWrite(5, HIGH);

break;

case 'e':

digitalWrite(6, HIGH);

break;

default:

// turn all the LEDs off:

for (int thisPin = 2; thisPin < 7; thisPin++) {

digitalWrite(thisPin, LOW);

}

}

}
}
