#include <Keyboard.h>

void setup() {
Keyboard.begin();

pinMode(2, INPUT);
pinMode(3, INPUT);

}

void loop() {
if (digitalRead(2) == HIGH) {
Keyboard.press('A');
delay(0);
}

if (digitalRead(2) == LOW) {
Keyboard.releaseAll();
delay(0);
}

if (digitalRead(3) == HIGH) {
Keyboard.press('B');
Keyboard.releaseAll();
delay(0);
}

if (digitalRead(3) == LOW) {
Keyboard.releaseAll();
delay(0);
}
}
