Introduction: Node Mcu Indian Car Central Lock With Rfid and Blynk Timer Unlock
I am showing you today an indian style car fully automated central lock with rfid tag blynk wifi control and time unlock .it also has all the features of a normal central lock.
this car central lock WORKS OFFLINE ACTIVATION REQUIRES NETWORK
LOCKS AND UNLOCKS WITH DRIVER SIDE DOOR SENSOR
CHEAP EASY TO MAKE
SEE COMMENTS TO SEE UPDATE CATALOGS
All the above items will be available in Amazon
acess codes __
ip = ip address of esp or its dns address
ip/data displays door data
ip/lock = locks car
ip/unlock = unlocks car
ip = shows data on car like owner info
#### NEW 2021 UPDATE #### THIS VERSION IS NOT MAINTAINED ANYMORE CONVERTED EVERYTHING TO ESP32
converted to esp32 and new blynk beta moving from just a lock to full car manager temperature monitoring,climate control ac, mist remover ,indoor light control,door open warning,handbrake warning,auto car moving lock car stop unlock and many more are added
new hardware esp32 mpu6050 ds18b20 many new connections,etc
#### NEW 2020 UPDATE ####
features (updated on 31 oct 2020 )
keeps data of lock and unlocking including time
unlock all locks if driver side lock is unlocked
unlock car via blynk unlock car via local html (new)
timer based car unlocking like unlocking on 8 am and locking on night you can set it like setting an alarm
main feature rfid based unlocking
and a sectret unlocking feature (new)
added led on D8
locking and unlocking car with the handle knocks see arduino based knock locks, sensor on pin A0
i am useing this in my car so i will always update and clear bugs but sometimes i wont post in github so text me for latest code
Supplies
Node mcu
Relay 2 channel
Door actuator 2 wire. X 3
Door actuator 5 wire x1
Rfid.
Wires
12v to 5v conveter
Step 1: Step 1 Connection of Rfid
Look at THE circuits above combine them all so you will get a full circuit. i will also explain it
First you need to connect rfid to node mcu use connective wires you can solder or use male femail connective wires. For that Connect
D3 To RST OF MFRC522
D4 To SDA OF MFRC522
D5 TO SCK OF MFRC522
D6 To MISO OF MFRC522
D7 To MOSI OF MFRC522
PROVIDE 3.3V AND GND TO MFRC522 BY ANY 3.3 AND GND PIN OF NODEMCU DO NOT USE 5V
Now rfid is sucessfully connected
see last step for seeing how i connected
this is the connection of car central lock
Step 2: Connection of Actuator Motor
PLease Wire up relay like in the picture.you can use 2 channel relay
Connect
RELAY SIGNAL 1 TO D0
RELAY SIGNAL 2 TO D2
VCC TO 5v from the converter
GND to GND
NOW I AM SAYING THE MAIN PART CONNECTING ACTUATOR MOTORS
CONNECT
GREEN AND BLUE WIRES OF ALL ACTUT MOTOR TO CENTRE OF RELAY
CONNECT NORMALY CLOSED OF RELAY TO GND OF 12V OF CAR BATTERY
CONNECT NORMALLY OPEN TO 12V OF CAR BATTERY
if your car is locking while clicking unlock filp the relay signal wires

Step 3: CONNECTION OF DOOR SENSOR
DOOR SENSORS ARE DESIGNED TO OPEN ALL DOORS IF DRIVERSIDE DOOR IS OPENED/CLOSED MANUALLY SO WE USE 5WIRE ACTUATOR MOTOR IN DRIVER SIDE
SO CONNECT
BLACK WIRE OF 5 WIRE ACTUATOR TO D1 OF NODEMCU
WHITE WIRE OF 5 WIRE ACTUATOR TO 3.3 V
GREY WIRE OF 5 WIRE ACTUATOR TO 0 V
if you are struck in endless loop like unlocking and locking automatically,flip the 3v and ov lines

Step 4: NOW THE POWER FOR EVERYTHING
USE CAN USE THE 12V OF CAR BATTERY TO POWER THIS ENTIRE THING YOU NEED TO CONNECT THE WIRE DIRECTLY TO BATTERY WITH A FUSE. ACC OR KEY ON DONT WORK.
YOU NEED A 12V TO 5V CONVERTER USE IT TO POWER THE NODE MCU AND RELAY
CONNECT 5V TO VCC
GND TO 0V
CONNECT 12V TO RELAY AS IN STEP 2
this is power wiring of how to make car central lock instractble page
Step 5: NEXT IS THE BLYNK APP TO CONTROL IT VIA WIFI AND MONITOR IT
I HAVE MADE A GOOD UI WITH LCD, TERMINAL,2 BUTTONS LOCK AND UNLOCK ,AN EVENTOR SO THAT YOU CAN SET TIME UNLOCK IF YOU NEED TO LOCK AT SOME TIME EG 9 O'CLOCK NIGHT
SO CHECK IT AND MODIFY TIME UNLOCK BASED ON YOUR NEEDS
I AM PROVIDING A QR CODE TO CLONE MY UI
this is blynk setup of how to make car central lock instractble page
bUTTON ON V1 TO LOCK
button on v2 to unlock
led on v10
rtc
eventer for setting alarm locking
terminal on v40
and many more if you know basic codeing please find out
Step 6: NEXT IS THE MCU CODING
I AM INCLUDING A FILE AND ALSO A GITHUB LINK CHANGE WIFI SSID AND PASSWORD WITH YOUR PHONE HOTSPOT (SWICH IT ON ALWAYS TO GET THIS THING CONNECTED))
AND ALSO CHANGE AUTH TOKEN WITH YOURS
ALSO CHANGE YOUR RFID CARD ID WITH YOURS(SEE THIS TO FIND
CARD UID https://www.instructables.com/id/MFRC522-RFID-Read...))
...........\...\...
... I Will try my maximum to improve my code i am currently working on ,sleep at night ,offline mode,auto unlock delay and many more
[[[[edit: ADDED OTA DISTANCE BASED UNLOCKING AND OFFLINE MODE AUTO UNLOCK DELAY AND MADE EVERYTHING OFFLINE ALSO ADDED MANY FEATURES AFTER THIS DIDNT HAVE TIME TO TYPE FEATURES HERE]]]]]

Step 8: Conclusion
THIS IS MY FIRST INSTRUCTABLES
SO I KNOW IT HAS MISSINGS
I AM POSTING THIS ONLY FOR ONE REASON BECAUSE THERE IS NO CAR LOCK LIKE THIS
SO I WANT TO HELP
ANYONE CAN POST THIS PROJECT IN YOUR BLOG OR ANYWHERE
BUT PLEASE ADD MY NAME IN YOUR CREDITS LIST
SORRY FOR MY BAD ENGLISH . I HAVE USED CAPITAL LETTER FOR MODERATE IMPORTANT SENTENSES AND BOLD FOR VERY IMPORTANT POINTS
IF YOU HAVE ANY DOUBTS TEXT ME MY EMAIL IS athulkrishna2711@gmail.com
I will be answering within 24 hr
Dont forget to add comments
