hello guys.. i have problem regarding my keypad coding..Its not working.. im doing a project interfacing a fingerprint scanner with the keypad..
this my keypad code with password:
{
lcd.setCursor(0,0);
lcd.print("Enter Password:");
customKey = customKeypad.getKey();
if (customKey){
Data[data_count] = customKey;
lcd.setCursor(data_count,1);
lcd.print(Data[data_count]);
data_count++;
}
if(data_count == Password_Length-1){
lcd.clear();
if(!strcmp(Data, Master)){
lcd.print("Correct");
delay(5000);
}
else{
lcd.print("Incorrect");
delay(1000);
}
lcd.clear();
clearData();
}
void clearData(){
while(data_count !=0){
Data[data_count--] = 0;
}
return;
this is my void loop :
void loop()
{
if(digitalRead(up)==0 || digitalRead(down)==0)
{
for(int i=0;i<5;i++)
{
lcd.clear();
lcd.print("Place Finger");
delay(2000);
int result=getFingerprintIDez();
if(result>=0)
{
digitalWrite(openLight, HIGH);
digitalWrite(closeLight, LOW);
lcd.clear();
lcd.print("Verification no.");
lcd.setCursor(0,1);
lcd.print("has been send");
delay(3000);
lcd.clear();
lcd.print("Please check");
lcd.setCursor(0,1);
lcd.print("your mobile");
delay(3000);
open_close_motor();
delay(1000);
lcd.clear();
lcd.begin(16,2);
lcd.backlight();{
{
lcd.setCursor(0,0);
lcd.print("Enter Password:");
customKey = customKeypad.getKey();
if (customKey){
Data[data_count] = customKey;
lcd.setCursor(data_count,1);
lcd.print(Data[data_count]);
data_count++;
}
if(data_count == Password_Length-1){
lcd.clear();
if(!strcmp(Data, Master)){
lcd.print("Correct");
delay(5000);
}
else{
lcd.print("Incorrect");
delay(1000);
}
lcd.clear();
clearData();
}
return;
}
}
}
checkKeys();
delay(2000);
}
Any help fixing my void loop would be appreciate
