Project : Face Your Fear (Arduino code for processing controlling servo)

Arduino Code (FYF Phase 1 Processing controlling Servo)

 char val; // Data received from the serial port
 int ledPin = 13; // Set the pin to digital I/O 13
 #include <Servo.h>
 Servo servo1;

 void setup() {
   pinMode(ledPin, OUTPUT); // Set pin as OUTPUT
   Serial.begin(9600); // Start serial communication at 9600 bps
   servo1.attach(9);
 }

 void loop() {
   if (Serial.available()) 
   { // If data is available to read,
     val = Serial.read(); // read it and store it in val
   }
   
     servo1.write(2*int(val)); // turn the LED on
  
   delay(10); // Wait 10 milliseconds for next reading
