![]() Switch case statements are useful when you have multiple ranges of inputs, and need to do something different for each range. The code is simpler, faster, and more optimized. ![]() In particular, a switch statement compares the value of a variable to the values specified in case statements. The switch case statement replaces the need for multiple if statements when you have multiple conditions that need to be tested. In this little "project" i'm asked to have a analog sensor which is the potentiometer, regulating the tone of a piezo buzzer using five switch cases according to the analog reading. I have put the code in the case statements, I have put the code within loops within the case statements, I have done everything I can think of. Here, we will discuss a project to turn ON one led from multiple LEDs based on the value in the variable. Like if statements, switch case controls the flow of programs by allowing programmers to specify different code that should be executed in various conditions. When using a switch case, the program will take a variable, in the example below it is range, and compare it to several cases. A switch case statement is used in place of multiple if statements. I'm new around here, and also new about the introduction to arduino and C. In this example the user will learn to use a switch case statement. if you want to convert if statement to Switch ,i.
