Not displaying anything

[krinton]

Hi, I hooked up the connection as it was suggested and nothing is displaying on the Serial Monitor. I am using Arduino 1.8.7 IDE. I have attached the picture below.

And i used this code from OneWireKeypad_Final from the file.

include

char KEYS[] = { '1', '2', '3', 'A', '4', '5', '6', 'B', '7', '8', '9', 'C', '*', '0', '#', 'D' };

OnewireKeypad <Print, 16 > KP2(Serial, KEYS, 4, 4, A1, 4700, 1000 );

void setup () { Serial.begin(9600); KP2.SetKeypadVoltage(5.0); }

void loop() { // if( KP.Getkey() ) // { // Lcd.clear(); // Lcd.home(); // Lcd.print( F( "KP: " ) ); // Lcd.setCursor(4,0); // KP.LatchKey(); // }

if ( char key = KP2.Getkey() ) { Serial << "Key: " << key << " State: "; switch (KP2.Key_State()) { case PRESSED: Serial.println("PRESSED"); break;

  case RELEASED:
    Serial.println("RELEASED");
    break;

  case HELD:
    Serial.println("HOLDING");
    break;
}

} }

Honestly speaking none of the code displays anything on the scree. Please Suggest. Thanks.

I added KP2.SetAnalogPinRange(1023) in the setup function, it displays but i can press few numbers only and no matter what I press it displays 'D' only.

Make sure your serial monitor BAUD rate matches what you set it to, 9600.

Remove this line: KP2.SetKeypadVoltage(5.0);

You need to use either both setKeypad voltage and pin or neither of them.

Double check your wiring too.

Still the same issue and result. It displays only key pressed as D.

[AndrewMascolo]

There is a function called ShowRange() see what values it returns. If you see all zeros for V or AR then you have something setup incorrectly. Possibly the keypad it self is wired incorrectly.

Thanks. Funny thing is it does not display as V and VR as I have seen with other people posting in other issues. Mine shows Probably i am doing something wrong and when I run Password function it shows password.h file is missing. Which i couldnot find the zip folder either.

[AndrewMascolo]

Password.h is not mine, that is a separate class you need to download.

When was the last time you updated the OneWireKeypadLibrary?

I see, you are using the ShowRange Example sketch.

Don’t use that, there is a function in the OWKP class called ShowRange, please use that.
