Arduino Tutorial | Bare Minimum code needed
Arduino Tutorial | Bare Minimum code needed Mr.Easy Arduino, This example contains the bare minimum of code you need for a sketch to compile properly on Arduino Software (IDE): the setup() method and the loop() method. Hardware Required ◆ Arduino or Genuino Board Circuit Only your Arduino or Genuino Board is needed for this example. image developed using Fritzing . For more circuit examples, see the Fritzing project page Code The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup function will only run once, after each powerup or reset of the board. After creating a setup() function, the loop() function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond as it runs. Code in the loop() section of your sketch is used to actively control the board. The code below...
