Code Basics -Arduino C The Arduino uses a slightly reduced C/C++ programming language. In this recipe, we will remember a few basics of C/C++. Ensure that you have Arduino IDE Installed on your Laptop/PC. Here is a simple example of basic Arduino C/C++ manipulating two variables: // Global Variables  int var1 = 10;  int var2 = 20; void setup() {   // Only execute once when the Arduino boots   var2 = 5;   // var2 becomes 5 once the Arduino boots } void loop(){   // Code executes top-down and repeats continuously   if (var1 > var2) {  // If var1 is greater than var2 var2++; // Increment var2 by 1   } else {  // If var1 is NOT greater than var2     var2 = 0; // var2 becomes 0   }  } When we upload a sketch to the board, the Arduino software first compiles the code. If there is an error in the code, it will write it in the Status D...
