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

int pinSignal = A0; // pin connected to pin O module sound sensor  
int redLed = 5;

long sum = 0 ; // Store the total value of n measurements   
long level = 0 ; // Store the average value   
int soundlow = 40;
