what is an arduino code example

Example 1: what programming language does arduino use

the C programming language but you can make it use C++

Example 2: what isarduino board

It is an open source electronic platform that is able to read any inputs and turn them into outputs by sending instructions to the microcontroller on the Arduino board using the Arduino software (IDE), it’s an inexpensive and simple platform that runs on different operating systems.

Example 3: arduino and

if (val == val && val == val)

Example 4: arduino

void setup(){}
void loop(){}

Example 5: Arduino

#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,10,11,12,13);
 
int num_Measure = 128 ; // Set the number of measurements   
int pinSignal = A0; // pin connected to pin O module sound sensor  
int redLed = 5; 
long Sound_signal;    // Store the value read Sound Sensor   
long sum = 0 ; // Store the total value of n measurements   
long level = 0 ; // Store the average value   
int soundlow = 40;
int soundmedium = 500;
 
void setup ()  
{   
  pinMode (pinSignal, INPUT); // Set the signal pin as input   
  Serial.begin (9600); 
  lcd.begin(16,2); 
}  
   
void loop ()  
{  
  // Performs 128 signal readings   
  for ( int i = 0 ; i <num_Measure; i ++)  
  {  
   Sound_signal = analogRead (pinSignal);  
    sum =sum + Sound_signal;  
  }  
 
  level = sum / num_Measure; // Calculate the average value   
  Serial.print("Sound Level: ");
  lcd.print("Sound Level= ");
  Serial.println (level-33);  
  lcd.print(level-33);
  if(level-33<soundlow)
  {
    lcd.setCursor(0,2);
    lcd.print("Intensity= Low");
     digitalWrite(redLed,LOW);
  }
  if(level-33>soundlow && level-33<soundmedium)
  {
    lcd.setCursor(0,2);
    lcd.print("Intensity=Medium"); 
     digitalWrite(redLed,LOW); 
  }
  if(level-33>soundmedium)
  {
    lcd.setCursor(0,2);
    lcd.print("Intensity= High");   
    digitalWrite(redLed,HIGH); 
  }
  sum = 0 ; // Reset the sum of the measurement values  
  delay(200);
  lcd.clear();
}
