Detailed explanation-3: -The setup() function is called once when your program starts. Use it to initialize pin modes, or begin serial.
Detailed explanation-4: -Use the Arduino IDE to create, open, and modify sketches that define what the board will do. You can use buttons along the top of the IDE to perform these actions (shown in Figure 1-5), or you can use the menus or keyboard shortcuts (shown in Figure 1-6).
