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:
|
||||
* 5 LEDs attached to digital pins 2 through 6 through 220-ohm resistors

||||

||||

// 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 exmaple, 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 'e':

// turn all the LEDs off:

digitalWrite(thisPin, LOW);
