Waoclowr 5-Way Navigation Button Module 5D Rocker Microcontroller Practical Keyboard Switch

4. Solder the pin header and use a wire to connect the GND connector to the GND of the microcontroller or other modules; connect the pins in the five directions to the corresponding Io port pins of the microcontroller; 3. The five way switch module can control the five Io ports of the microcontroller, it is moved up, down, left, right and middle. It offers the advantages of easy operation and stable function. Features: 1. This corresponds to 5 key switches 2. Set the pin header and connect it to the Io port of the microcontroller via the pin header. 5. When the button is switched, the corresponding Io port is shorted with Gnd to set the level status of the Io port to 0. Therefore, the microcontroller is set to the bi-directional 1o port. When the button is pressed, the level status is 0. The level status is 1 when pressed.
