im new to these thing.
i have install the hardware and the coding was fine but when i look at serial monitor i only get fingerprint result and nothing from keypad.
did i need to add code for keypad?
Where have you ever seen something like this?Serial.begin(16, 2);==> FIX IT
Try basic code for your keypad without the rest to see if you connected it properly
This part
char key = keypad.getKey();
if (key != NO_KEY){
delay(60);
switch (key){
case 'A': break;
case 'B': break;
case 'C': break;
case 'D': changePassword(); break;
case '#': checkPassword(); break;
case '*': resetPassword(); break;
default: processNumberKey(key);
}
would be better located in the loop as it has nothing to do with the fingerprint
