apologize for my absent so many years.

I was working in Dubai for 4 years and really didnt have a time to login. I have more than a flight per day, so you understand that i wasnt able at all to handle many things at a time.

Now im back to real life, and i will upload the code and the circuits as well tonight.

Imagine that for so long time, the circuit remains the same in my lab, and i havent done anything to it yet apart from adding a second circuit, beside it with a keypad.

None of the core of the codes are mine, i just did some configurations and changes to fit my needs. (im not proud of this, as i would like ones to write completely my own code from the scratch)

The following image shows the circuit and the connection of one circuit to an other.

I know that it is difficult to understand the schematic, as it is not corresponds at the moment to a circuit, but i have it on a TEST Board and i can do a small video of it.

As i have mentioned, there are two circuits, separated, the RFID circuit (with the uLCD) and the CODELOCK with keyboard.

What the circuit does:

1) once you place the Tag to the RFID reader, the uLCD, displays the picture of the person carries the RFID tag
2) at the same time, a BEEP on the buzzer is activated and sends a command to activate the second circuit.
3) You have 5 seconds until you add the code on the keypad otherwise the circuit lose its power and is not activated any more.
