Aruino test code:
/ / ADKeyboard Module
int adc_key_val [5] = {50, 200, 400, 600, 800};
int NUM_KEYS = 5;
int adc_key_in;
int key = -1;
int oldkey = -1;
void setup ()
{
pinMode (13, OUTPUT); / / we'll use the debug LED to output a heartbeat
Serial.begin (9600); / / 9600 bps
}
void loop ()
{
adc_key_in = analogRead (0); / / read the value from the sensor
digitalWrite (13, LOW);
key = get_key (adc_key_in); / / convert into key press
 
if (key! = oldkey) / / if keypress is detected
{
delay (50); / / wait for debounce time
adc_key_in = analogRead (0); / / read the value from the sensor
key = get_key (adc_key_in); / / convert into key press
if (key! = oldkey)
{
oldkey = key;
if (key> = 0) {
digitalWrite (13, HIGH);
switch (key)
{
case 0: Serial.println ("S1 OK");
break;
case 1: Serial.println ("S2 OK");
break;
case 2: Serial.println ("S3 OK");
break;
case 3: Serial.println ("S4 OK");
break;
case 4: Serial.println ("S5 OK");
break;
}
}
}
}
delay (100);
}
/ / Convert ADC value to key number
int get_key (unsigned int input)
{
int k;
for (k = 0; k <NUM_KEYS; k + +)
{

{
return k;
}
}
if (k> = NUM_KEYS) k = -1; / / No valid key pressed
return k;
