I am trying to make Arduino uno to act as a keyboard, i have successfully flashed the USB-HID firmware in it using this link also and programmed it like this.
uint8_t buf[8] = {
0
};
int inpin1 = 7;
int inpin2 = 8;
int val1 = 0;
int val2 = 0;
void setup()
{
Serial.begin(9600);
delay(200);
pinMode(inpin1, INPUT);
pinMode(inpin2, INPUT);
}
void loop()
{
val1 = digitalRead(inpin1);
if(val1 != HIGH)
{
buf[2] = 80; // Left Arrow
Serial.write(buf, 8);
releaseKey();
}
val2 = digitalRead(inpin2);
if(val2 != HIGH)
{
buf[2] = 79; // Right Arrow
Serial.write(buf, 8);
releaseKey();
}
}
void releaseKey()
{
buf[0] = 0;
buf[2] = 0;
Serial.write(buf, 8);
}
The above code works fine but the problem is that, when i tried to play a game which uses right arrow and left arrow and to control car i was using the push button which i connected to arduino as left and right arrow keys. But suppose if i want to turn a car. I have to press the key and then release the key to move it a very little to the right or left. So, if i want to turn the car either left or right, i have to press and release so many times that it becomes impossible to play the game. Do you anyone know how to resolve this problem.
