c++ arduino serial communication

 

Serial Communication with C++ Project. C++ windows application
with Arduino nano Communication Serial A photoresistor or light-dependent

 

Parts Required:

1. Arduino NANO
2. LDR (1)
3. LCD 16×2 (1)
4. Wires to connect it all together

 

#include <LiquidCrystal.h>

const int buttonPin = A2;
const int ledPin =  8;
int buttonState = 0;
int ledstat = 0;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
const int sensorMin = 0;
const int sensorMax = 600;

void setup() {
pinMode(buttonPin, INPUT);

Serial.begin(9600);
lcd.begin(16, 2);
lcd.clear();
}

void loop() {

lcd.setCursor(0, 1);

int sr = analogRead(A2);
// map the sensor range to a range of four options:
int range = map(sr, 0, 1023, 0, 255);
lcd.print(sr);
delay(65);
lcd.clear();

if (sr < 5){
Serial.print(0);
}
else
Serial.println(1);

}
