#### What is it?

This is an Arduino uno based RFID RC522 lcd 1602 prototype PCB, the PCB design is being changed to make it more attractive and easy to use. The PCB image in black colour is the older one and glossy. Thanks to pcbway for their Amazing quality pcb for my project.

#### Why did you make it?

The reason to make this project pcb is because nowadays engineers who want to keep their workshop materials and place safe make use of solenoid lock with the rfid RC522 module. They make the project either in ZERO pcb or perf board and even sometimes in Breadboard. Do taking the security into consideration this project is engineer friendly with less mess and high work.

The PCB only has space for Resistor, potentiometer, lcd 1602 and rfid RC522 module. So if an engineer is developing its solenoid security based lock, then the wiring of the solenoid needs to be done more. The engineer can then solder the relay to the pcb with a bit of wire and core solder. Then the job is done, hence didn't add its place in pcb but definitely tried to make the same. 

#### What makes it special?

The project is special because it is in the size of an Arduino uno, i.e we can directly add the male header and fix it to the Arduino uno easily. I will upload the video of the arrangement in the pcb if you didn't understand the concept in written.

The place for the resistor is provided in case the power supply to the LCD is too high. Then you can add a 10k, 20k or any preferable resistor. 

LET US HAVE A LOOK AT THE COMPONENTS REQUIRED:)

RFID RC522

MF RC522 is a highly integrated read and write card chip applied to the 13.56MHz contactless communication. Launched by the NXP Company, it is a low-voltage, low-cost, and small-sized non-contact card chip, a best choice for intelligent instrument and portable handheld devices.

LCD 1602

 LCD1602, or 1602 character-type liquid crystal display, is a kind of dot matrix module to show letters, numbers, and characters and so on. ... The model 1602 means it displays 2 lines of 16 characters. Generally, LCD1602 has parallel ports, that is, it would control several pins at the same time.......

THIS IS A VERY INSPIRATIONAL PROJECT FOR ME:)

GOOD BYE , CHECK THE LINKS MENTIONED BELOW....
