Clavier USB et Souris

Installation et test de la carte : https://www.arduino.cc/en/Guide/ArduinoLeonardoMicro

Clavier (attention avec un clavier sans pavé numérique le « 1 » = »<shift>1″

/*
************ LEONARDO TOUCH ****************
Simultation enter the 1 touch of the keyboard
With a keyboard with Shift combinaison for numbers
The circuit:
– pushbutton attached from pin 4 to +5V
– 10 kilohm resistor attached from pin 4 to ground

See https://www.arduino.cc/en/Reference/KeyboardModifiers

Souris:

#include « Mouse.h »

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
Mouse.begin();

}

void LedBlink(int nb, int tempo) {
for (int i= 1 ; i<=nb; i++) {
digitalWrite(LED_BUILTIN, HIGH);
delay(tempo);
digitalWrite(LED_BUILTIN, LOW);
delay(tempo);
}
}
// the loop function runs over and over again forever
void loop() {
//digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
Mouse.move(0, -1);
delay(2000);
Mouse.move(0, 1);
//digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Test du sketch http://arduino.cc/en/Tutorial/KeyboardLogout avec une carte Arduino Leonardo.

1°) Préparation, prévoir un fil à relier de la broche 2 (digitale) à la masse

2°) Raccordement de la carte au PC et déchargement du sketch

3°) Branchement de la carte sur le port USB d’un PC (test sous windows et ubuntu)

4°) Relier le fil de la broche 2 à la masse pour lancer le reboot du pc
