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
