Arduino Rfid Read and Write on Lcd

i will show you how to make arduino rfid read and write on lcd

Step 1:

Hi there!

Today i will show you how to make arduino rfid read and write on lcd. Download the code and load it on arduino it does not matter witch one but i prefer uno and infiduino.

Things you will need:

*lcd (16,2) eny one i used 16 by 2

*rfid (rc522)

*rfid tag

*breadboard

*some jumpers

*pot (10k)

Step 2: Lcd Pinout

Connect rfid scenner and lcd to arduino as showned on schematic and dont forget pu put pot on vo of the lcd if you dont you will se apsulutly nothing.

Lcd connections

vss - to gnd

vdd - to 5v

vo - to pot

rs - to arduino digital pit 7

rw - to gnd

e - to arduino digital pin 6

d4 - to arduino digital pin 5

d5 - to arduino digital pin 4

d6 - to arduino digital pin 3

d7 - to arduino digital pin 2

A - to arduino digital pin 8

K - to gnd

Step 3: Rfid Pinout

3,3 - to arduino 3,3 volt rail

rst - to arduino digital pin 9

gnd - to arduino gnd rail

rqi - not connected

miso - to arduino digital pin 12

mosi - to arduino digital pin 11

sck - to arduino digital pin 13

sda - to arduino digital pin 10

Step 4: Trying It Out

when you are all done connect arduino to power sorse and wait to arduino turn lcds back light when che lcd cleans scan rfid card then go thro the progrem when is over it will say success 16:-) the lcds back lights will turn off then reset your arduino to start program over again.

thanks enjoy
