Switch (case) Statement, used with sensor input - Arduino Docs
Oct 2, 2024 · This tutorial shows you how to use it to switch between four desired states of a photo resistor: really dark, dim, medium, and bright. This program first reads the photoresistor. Then it uses the map function to map its output to one of four values: 0, 1, 2, or 3. Finally, it …
switch...case - Arduino Docs
May 21, 2024 · Like if statements, switch case controls the flow of programs by allowing programmers to specify different code that should be executed in various conditions. In particular, a switch statement compares the value of a variable to the values specified in case statements.

Switch (case) Statement, used with serial input - Arduino Docs
Oct 2, 2024 · This tutorial shows you how to use switch to turn on one of several different LEDs based on a byte of data received serially. The sketch listens for serial input, and turns on a different LED for the characters a, b, c, d, or e.
Beginners: using the switch - case statement - Arduino Forum
Oct 27, 2020 · The switch - case statement is a powerful construct that is often under-used by beginners. Basically it allows you to perform tests on a value (or range of values) and make decisions - a bit like the IF statement.
Multiple Button Switches - Easy & Effective Polling - Arduino …
Feb 15, 2021 · This sketch will reliably read any number of button switches by polling each of them in turn. Once a button switch is pressed the main code loop will switch to user provided code to handle the purpose of the button press. This is controlled via a switch control struct(ure) and associated switch-case code.
