The Rotary Encoder detects rotational movement and its direction using two out-of-phase signals. Some rotary encoders also include an integrated push button switch, which is ideal for navigating menu-driven user interfaces or other interactive projects.
The Color Touch Sensor functions similarly to a regular touch sensor but retains its previous state, toggling its logic state each time it is touched. It also features a colored backlight indicator, which is ON for logic HIGH (1) and OFF for logic LOW (0).
A Touch Sensor is a type of switch that changes to a logic HIGH (1) state when touched and returns to a logic LOW (0) state when released.
A Rocker Switch is a type of switch that maintains its state when toggled, staying ON or OFF until manually changed again.
Buttons are a type of momentary switch that changes state when pressed and returns to its previous state when released. They are commonly used as user input devices in electronic projects.
