Topic: Schematic and code needed for RFID Door lock. PAYMENT IS 60$ or more if needed (Read 2273 times) previous topic - next topic


I am making a RFID door lock.

Of course i will pay for it.
What i basically need:

The project consists of 2 boxes. An outer box which houses the keypad, the LCD and the RFID reader as well as a smaller speaker and the LED's.

The inner box houses the Arduino (Either mega or Uno) as well as the servo and the other components.

I need 3 LED's:

A green one that lights up when the card is correct.
A red one that lights up when the card is incorrect.
A orange LED that indicates a button is pushed on the keypad.

I need an LCD which displays when acces is granted or denied, and maybe "Welcome" to whoever the tag belongs to.

I need a keypad so i can imput a 4 digit code.

I need a reset button on the arduino to reset all tags or program a new one.

I need a small speaker (Piezo) which gives different sounds if the card is correct or incorrect. i also need the speaker to indicate whether or not a key is pressed, as well as put out a voice saying "Access granted".

I now found some sounds (Access granted, access denied) that i want to play when it's correct or incorrect.

When the key is entered correct or if a tag is scanned, i want the servo to turn the lock.

I will pay for the work and i can Skype about the project.

How much would it cost?


The LCD, LEDs, Keypad, switches, noise maker, and RFID reader are relatively simple. The hard part is actually opening the lock when the appropriate RFID tag is waved/code is entered.

How are you planning to actually activate/deactivate the lock?

Connecting the components is not difficult. Making a professional looking enclosure could be. Making something that goes with your decor could be even more challenging.
The art of getting good answers lies in asking good questions.


To activate or deactivate the lock you have to put a tag in front of it.

When a code is entered or a correct tag is registrered, the servo has to turn the lock.

Proffessional enclosure is not that hard for me :)


the servo has to turn the lock.

Have you verified that the servo you have chosen is capable of turning the lock? What amount of movement of the servo is needed? How are the Arduino and servo (to be) powered?

The Arduino and servo can either be powered by a regular power or by rechargeble batteries.

The servo i ordered is a MG996R Metal Gear Digital Torque Servo.

These are the specifications:

Dimension : 40mm x 19mm x 43mm
Weight : 55g
Operating Speed : 0.17sec / 60 degrees (4.8V no load)
Operating Speed : 0.13sec / 60 degrees (6.0V no load)
Stall Torque : 13 kg-cm (180.5 oz-in) at 4.8V
Stall Torque : 15 kg-cm (208.3 oz-in) at 6V
Operation Voltage : 4.8 - 7.2Volts
Gear Type: All Metal Gears
Connector Wire: Heavy Duty, 11.81" (300mm)

Furthermore i found this:

But when i have uploaded the code to the Arduino and wired the Arduino correctly, it does not show any information at the "Serial monitor".

Nothing when a card is placed in front of it.

Anyone who wants to do such a job? :)
