What is if else statement in Arduino?
The if… else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped. An else clause (if at all exists) will be executed if the condition in the if statement results in false .
How many else if statements can you have Arduino?
Note that an else if block may be used with or without a terminating else block and vice versa. An unlimited number of such else if branches is allowed. Another way to express branching, mutually exclusive tests, is with the switch case statement.

How is the if statement written in Arduino?
This is written as: If the counter is less than 10, the program will not proceed and loop within the ‘if’ statement. To blink the LED, we will simply digitally write the pin HIGH and LOW with a delay of 500 milliseconds. This will blink the LED once, so we must record this blink to ‘Count’.
When to add an else statement to an IF statement?
By adding an else statement, the code in the body of the else statement will run, but only when its corresponding if statement evaluates to false. When the conditional expression evaluates to true: Code in the body of the if statement runs. Code in the body of the else statement does not run.
