Hi
I am new to arduino env.
I am trying to below program of password lock on Attiny85. But i am not able to write to EEPROM.
Anybody help me. Thanks in advance.
#include <AnalogMatrixKeypad.h>
#include <Password.h>
#include <EEPROM.h>
char* secretCode = "3456";
int analogPin = A1; // TINY 85 IC Pin No. 7 (IC Pin No.8 to 5V) Analog Signal from one wire keyboard
AnalogMatrixKeypad AnMatrixKeypad(analogPin);
Password password = Password (secretCode);
Password MstrPW = Password ("496321");
boolean locked = true;
int redPin = 5; // TINY 85 IC Pin No. 1 Not usable as it is reset pin, hence connected to closepin
int greenPin = 3; // TINY 85 IC Pin No. 2
int bluePin = 4; // TINY 85 IC Pin No. 3
int openpin = 1; // TINY 85 IC Pin No. 6
int closepin = 0; // TINY 85 IC Pin No. 5
int j=0;
