Using Wio Terminal as a Keyboard

This wiki introduces how to use the Wio Terminal as a simple keyboard. It has assigned the 3 keys s, e, d to the 3 buttons on the Wio Terminal. This can be easily implemented into your design for more challenging tasks.

Installing Libraries

This example also requires an additional Arduino keyboard library:

  1. Visit the Arduino Keyboard Library repository and download the entire repo to your local drive.

  2. Now, the library can be installed to the Arduino IDE. Open the Arduino IDE, and click sketch -> Include Library -> Add .ZIP Library, and choose the Keyboard-master file that you have just downloaded.


Complete Code

For more functionality, please refer the official keyboard functions from Arduino.

#include "Keyboard.h" //keyboard library 

void setup() {
//set button pins as inputs
pinMode(WIO_KEY_A, INPUT);
pinMode(WIO_KEY_B, INPUT);
pinMode(WIO_KEY_C, INPUT);

Keyboard.begin(); //start keyboard communication

void loop() {
if (digitalRead(WIO_KEY_A) == LOW) { //detect button press
Keyboard.write('s'); //single key is pressed (character)
if (digitalRead(WIO_KEY_B) == LOW) {
if (digitalRead(WIO_KEY_C) == LOW) {

delay(200); //delay between keypresses
