The FLiP - RFID Reader with EEPROM Names program is the complete Blockly example shown in the video on the first page of this project. The program has three main functions which are quite easy to understand.
The “check for a match and update OLED” function is where the scanned RFID tag number is read and compared to a RFID tag number stored in EEPROM at 20 byte increments. If a match is found, the first and last names are also retrieved. This is done by incrementing an EEPROM location pointer by 4 and 12 bytes, storing the names in firstName and lastName, and writing them to the OLED.
