= comparison operator, other operators like == (equal to), > (greater than), < (less than) , >= (greater than or equal to) and <= (less than or equal to) can also be used when writing Arduino code. Using the comparison operators properly is important for ensuring your program ...
Arduino if else: How to use the Arduino 'if-else' statement, and use its different forms in your code - long form and compact. Learn about the ternary operator (?) for ultra-compact conditional operation. The Arduino if else statement : ...
