Thanks a lot. :)im not 100% of Arduino knowledge, i just want to share what i learnt to other people so it can be useful.the difference between NodeMCU first version and the V3 is in pin configuration V3 has addition pin VUSB, V3 use CH340 to comunicate with PC while NodeMCU use CP2102.
have you downloaded my program?if you already download, goto line number 192,thats subroutine to store RFID in EEPROM.in line number 163 is to find stored RFID card in EEPROMRFID card store information that call nuidexampleA7 E2 55 1Bthat nuid will stored in 4 EEPROM register in this program i use register address 1000 to store A71001 E21002 551003 1B so on.....if you already install RC522 library, you can find this program in example RC522 - servo_motor.dont forget to vote me...:)
Thanks you, i hope with this project can help you to prevent your chicken stoled.you can also put a sensor like PIR sensor(motion sensor) and send the data to your website and show the data to your android.since this project use your own website, you can send data without delay(real-time) not like other IoT server provider that require delay for sending the data.dont forget to vote me.:)
