Join Zahraa Khalil for an in-depth discussion in this video Optional review: The switch...case statement, part of Learning Arduino: Interfacing with Hardware.
- [Instructor] All right, so I'm going…to go through the switch...case statement.…If you are familiar with the concept,…you can skip this video, but if you want to refresh…your memory about what the concept is,…I'm going to go through the concept briefly.…So one of the structure commands used…within Arduino is a switch...case statement.…Oftentimes, we might need to compare a variable…against several possible values.…For example, the keypad we're using,…so we might need to have an assorted output…to be associated when we press certain numbers…on the keypad.…
The switch statement uses a standard…if...then style condition to evaluate for results.…The Arduino jumps to the matching case statement…in the code, skipping over the other case statements.…You can have a default statement…at the end of the switch statement code block.…The Arduino software jumps to the default statement…when none of the cases matches the results.…So we use switch...case statement if we want…to control the flow of the program,…or if we want to switch between different states.…
