Hello everyone..i'm really need your help..i have a problem to understand how to control the brightness of LED using LDR for PIC16F..can you give me the sample coding??I'm really want to learn about it..i have found a sample of coding according to the title as shown below. However, it used an arduino microcontroller instead of PIC16F..please help me.. Thank you..

int sensorPin = A0;
int sensorPin1 = A1;
int sensorPin2 = A2;
int led = 11;
int sensorValue = 0;
int sensorValue1 = 0;
int sensorValue2 = 0;


void setup() {
  Serial.begin(9600);
  pinMode(led, OUTPUT);
  pinMode(sensorPin, INPUT);
  pinMode(sensorPin1, INPUT);
  pinMode(sensorPin2, INPUT);
}

void loop () {
  
  sensorValue  = analogRead(sensorPin);  
  sensorValue1 = analogRead(sensorPin1);
  sensorValue2 = analogRead(sensorPin2);
  
  if (sensorValue<500)
  {analogWrite(led, 50);}

  if (sensorValue1<500)
  {analogWrite(led, 150);}
 
  if (sensorValue2<500)
  {analogWrite(led, 255);}

  Serial.println(sensorValue);
  Serial.println(sensorValue1);
  Serial.println(sensorValue2);
  
  delay(10);
}

 

Why are you measuring 3 sensors to control 1 LED?

Please show a schematic, and a good description of WHAT the circuit needs to do and WHY.

 

You should start at the beginning and learn how to use the PIC before attempting to make this. Learn the parts and how they work, then you will be will equipped for the task at hand.

Look at the datasheet for the PIC you plan to use and read the pertinent sections (the ADC and PWM sections). You can't hope to make anything with a PIC without opening the datasheet.
