=== '''Photosensitive LED''' ===

'''Description'''
Since the photo resistor is an element that can change the resistance value according to the light intensity, the analog value needs to be read via analog port.
In this experiment, we design a circuit that reading different analog value and mapping analog value into PWM value under different light intensities, which controls the brightness of LED. Therefore, we achieve different brightness change of led as light intensity changes.



'''Equipment'''

* USB cable*1
* Micro control board*1
* LED*1 
* Photo resistor*1
* 220Ω Resistor*1
* 10KΩ Resistor*1
* Breadboard*1
* Male to female Dupont Lines
* Male to male Dupont Lines

'''Test Code'''

<pre>int ledpin=6;//define digital port 6 （PWM outputs）
void setup()
{
pinMode(ledpin,OUTPUT);//set digital port 6 to output
Serial.begin(9600);//set baud rate to 9600
}
void loop()
{
int val=analogRead(0);//read value of analog port A0
Serial.println(val);//display val variable
val = map(val, 0, 1023, 0, 255);//map form 0-1023 to 0-255
analogWrite(ledpin,255-val);// turn on LED and set the brightness
delay(10);//delay for 0.01s
}

Test Result After downloading the program, the photo resistor senses that the brighter the light, the darker the LED; it senses that the darker the light, the brighter the LED. Open the serial port monitor, set baud rate to 9600, and you can see the analog value of photo resistor that senses the external light intensity.
