    syntax) • 2 Main functions • setup() • Called once on the boot • loop() • Continuous loop ! ! • http://arduino.cc/en/Reference/HomePage int ledPin=8; ! void setup() { pinMode(ledPin,OUTPUT); } ! void loop() { digitalWrite(ledPin,1); delay(500); digitalWrite(ledPin,0); delay(500); }

  6. 5IFTFTMJEFTBSFDPQZSJHIU˜)JSPUBLB/BLBKJNB3FEJTUSJCVUFBOEEJTDMPTVSFPGUIFTFTMJEFTBSFOPUQFSNJUUFEXJUIPVUQFSNJTTJPOT ,FJP6OJWFSTJUZJTMJDFOTFECZJUTDPQZSJHIUIPMEFST Arduino: Function 6 • pinMode(pin, mode) • Configures

    the specified pin to behave either as input or output. • pinMode(8, OUTPUT);
 set the pin #8 as OUTPUT pin.

  7. 5IFTFTMJEFTBSFDPQZSJHIU˜)JSPUBLB/BLBKJNB3FEJTUSJCVUFBOEEJTDMPTVSFPGUIFTFTMJEFTBSFOPUQFSNJUUFEXJUIPVUQFSNJTTJPOT ,FJP6OJWFSTJUZJTMJDFOTFECZJUTDPQZSJHIUIPMEFST Digital Output 7 • Control On/Off • digitalWrite([PIN#],

    [Value]) • e.g.)
 setup(){
 int ledPin = 8; //LED is connected to digital output pin #8
 }
 
 loop(){
 digitalWrite(ledPin, HIGH); //set the LED on
 delay(1000); // wait for a second
 digitalWrite(ledPin, LOW); //set the LED off
 delay(1000); // wait for a second
 }

    to Wikipedia: • LED as light sensor:
 "A LED is simply a diode that has been doped specifically for efficient light emission and has been packaged in a transparent case. Therefore, if inserted into a circuit in the same way as a photodiode, which is essentially the same thing, the LED will perform the same function.” • Photodiode:
 "A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation."
