RFID Garage door opener

Hello BartE,
I have the same issue as cyberfilou...
Sketch works beautifully...but if I power off the Arduino (Pro Mini in my case) and power it on again, all stored cards are gone. Any ideas what could cause this, and how to prevent it?Thx a lot, Stefan

@SVLoneStar That is weird.
Do you get this message each time you boot the Arduino? "Not a valid EEPROM reading set to default"
What is the UID size (how many bytes) of the recorded cards? -
Hi BartE - thanks for your reply!
I do not receive any error regarding invalid EEPROM - not while writing, not at boot time.
My cards are shown in this format: D4 04 E2 E9
I register a Master Card like this (and it works until reboot):
MFRC522::Uid masterkey = { 4, {0xD4,0x04,0xE2,0xE9}, 0 }; -
Cool stuff! You probably what some signing in there as well :) would be a shame if someone snooped the open command from your controller and decided to pay a visit.

The function recallEeprom(); reads the EEPROM content and after closing the program mode this function storeEeprom();
writes the EEPROM. Please add some debug info (Serial.print) and validate that these functions actually are called on- recallEeprom(); --> on start up
- storeEeprom(); --> ending program mode.

@Anticimex yes your right but when i wrote this sketch signing was not in the released branch.

Nice work. I have yet to pick up an RFID reader to give that part of it a try, but I've modified it a little to have reed sensors for the 2 doors so that I can easily see if the door is open on my phone, and get notifications when the door opens at an unexpected time, like when the controller is set to vacation mode, or at times of night when we would not normally be coming and going.
I'll be watching for someone to post up a signing version.Here's my 2 relay, 2 door sensor version.
/* RFID Garagedoor opener by Bart Eversdijk Modified to add door sensors by Rod MacPherson This sketch is to open a Garage door with an mifare RIFD-tag For an Arduino Nano v3 Connection wiring : - nrf24l01+ as descibed on the MySensors website - MFRC522 reader/writer MOSI, MISO, SCK, 3.3V and GND as they are on the nrf24101+, but connect RST to pin D7 and connect SDA(SS) to pin D8 - LED with 470ohm resistor between GND and pin A3 - push button between GND and pin D5 - 5v relays coil between GND and pin D4 -> switch pins of the relays should be connected in parallel with your garage door push button. - second relay for second door on pin D3 Features: This project can record up to 18 RFID-"tags" These card IDs are stored in to EEPROM by keeping them next to the RFID reader when the system in program mode. (Slow blinking LED) When a card is accepted as new card the LED will blink fast for a short time. To keep the master-tags (choose your own) next to the RFID reader when pressing the push button. To clear all cards (except the master card) press the push button in program mode for 6 seconds. The LED will now fast blink for a couple of seconds. Your garage your can be opened by keep a registered RFID tag next to the reader or by clicking the open icon on lock node presented by this plugin. By by-passing the alarm node presented by this plug in the RFID will be temporarily disabled. When an incorrect (not registered) RFID tag is scanned the alarm is triggered to detect illegal scan attempts */ #include <SPI.h> #include <MFRC522.h> #include <MySensor.h> #include <Bounce2.h> #define RF_INIT_DELAY 125 #define ONE_SEC 1000 #define MAX_CARDS 18 #define PROG_WAIT 10 #define HEARTBEAT 10 #define BAUD 115200 /*Pin definitions*/ #define LED_PIN A3 #define SECONDRELAY 3 #define GARAGEPIN 4 #define SWITCH_PIN 5 #define RST_PIN 7 // MFRC #define SS_PIN 8 // MFRC #define DOOR_PIN_L A0 // Arduino Digital I/O pin for button/reed switch #define DOOR_PIN_R A1 // Arduino Digital I/O pin for button/reed switch MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance MFRC522::Uid olduid; MFRC522::Uid masterkey = { 10, {0,0,0,0, 0,0,0,0, 0,0 }, 0 }; byte countValidCards = 0; MFRC522::Uid validCards[MAX_CARDS]; void ShowCardData(MFRC522::Uid* uid); bool sameUid(MFRC522::Uid* old, MFRC522::Uid* check); void copyUid(MFRC522::Uid* src, MFRC522::Uid* dest); bool isValidCard(MFRC522::Uid* uid); int releasecnt = 0; #define CHILD_ID_ALARM 1 #define CHILD_ID_LOCK 2 #define CHILD_ID_LOCK2 3 #define CHILD_ID_DOOR_L 4 #define CHILD_ID_DOOR_R 5 MySensor gw; Bounce debouncer = Bounce(); Bounce debouncerDoorR = Bounce(); Bounce debouncerDoorL = Bounce(); int oldValueR=-1; int oldValueL=-1; int oldSwitchValue=-1; int switchValue = 0; long timer = -1; bool programmode = false; bool ledon; int programTimer = 0; bool armed = true; unsigned long lastTime = 0; MyMessage lockMsg(CHILD_ID_LOCK, V_LOCK_STATUS); MyMessage lock2Msg(CHILD_ID_LOCK2, V_LOCK_STATUS); MyMessage lockArmMsg(CHILD_ID_ALARM, V_ARMED); MyMessage wrongMsg(CHILD_ID_ALARM, V_TRIPPED); MyMessage doorRmsg(CHILD_ID_DOOR_R, V_TRIPPED); MyMessage doorLmsg(CHILD_ID_DOOR_L, V_TRIPPED); void setup() { Serial.begin(BAUD); // Initialize serial communications with the PC pinMode(GARAGEPIN, OUTPUT); // Initialise in/output ports pinMode(SECONDRELAY, OUTPUT); // Initialise in/output ports // Make sure MFRC will be disabled on the SPI bus pinMode(RST_PIN, OUTPUT); digitalWrite(RST_PIN, LOW); pinMode(SS_PIN, OUTPUT); digitalWrite(SS_PIN, LOW); pinMode(LED_PIN, OUTPUT); digitalWrite(LED_PIN, LOW); // Setup the button pinMode(SWITCH_PIN, INPUT_PULLUP); // After setting up the button, setup debouncer debouncer.attach(SWITCH_PIN); debouncer.interval(5); // Setup the right door sensor pinMode(DOOR_PIN_R,INPUT); // Activate internal pull-up digitalWrite(DOOR_PIN_R,HIGH); // After setting up the button, setup debouncer debouncerDoorR.attach(DOOR_PIN_R); debouncerDoorR.interval(5); // Setup the left door sensor pinMode(DOOR_PIN_L,INPUT); // Activate internal pull-up digitalWrite(DOOR_PIN_L,HIGH); // After setting up the button, setup debouncer debouncerDoorL.attach(DOOR_PIN_L); debouncerDoorL.interval(5); // Init mysensors library gw.begin(incomingMessage, 5); gw.sendSketchInfo("RFID Garage", "1.2"); delay(RF_INIT_DELAY); // Register all sensors to gw (they will be created as child devices) gw.present(CHILD_ID_LOCK, S_LOCK); delay(RF_INIT_DELAY); gw.present(CHILD_ID_LOCK2, S_LOCK); delay(RF_INIT_DELAY); gw.present(CHILD_ID_ALARM, S_MOTION); delay(RF_INIT_DELAY); gw.present(CHILD_ID_DOOR_R, S_DOOR); gw.present(CHILD_ID_DOOR_L, S_DOOR); recallEeprom(); // Init MFRC RFID sensor SPI.begin(); // Init SPI bus mfrc522.PCD_Init(); // Init MFRC522 ShowReaderDetails(); // Show details of PCD - MFRC522 Card Reader details gw.send(lockArmMsg.set(armed)); Serial.println(F("Init done...")); } void loop() { timer++; delay(HEARTBEAT); gw.process(); debouncer.update(); debouncerDoorL.update(); // Get the update value for Left int valueL = debouncerDoorL.read(); if (valueL != oldValueL) { // Send in the new value for Left gw.send(doorLmsg.set(valueL==HIGH ? 1 : 0)); oldValueL = valueL; } debouncerDoorR.update(); // Get the update value for Right int valueR = debouncerDoorR.read(); if (valueR != oldValueR) { // Send in the new value for Right gw.send(doorRmsg.set(valueR==HIGH ? 1 : 0)); oldValueR = valueR; } // Get the update value int switchValue = debouncer.read(); if (switchValue != oldSwitchValue) { // Send in the new value Serial.print (F("Switch ")); Serial.println (switchValue); if (switchValue && programmode) { lastTime = millis() / 1000; } if (!switchValue && programmode && lastTime > 0) { if ( (millis() / 1000) - lastTime > 3) { Serial.println(F("Reset all cards")); countValidCards = 0; blinkFast(50); } else { Serial.println(F("Program off")); digitalWrite(LED_PIN, LOW); programmode = false; storeEeprom(); } } if (!switchValue) { programTimer = 0; } oldSwitchValue = switchValue; } if (programmode && ((timer % (ONE_SEC / HEARTBEAT)) == 0 )) { ledon = !ledon; digitalWrite(LED_PIN, ledon); programTimer++; // Stop program mode after 20 sec inactivity if (programTimer > PROG_WAIT) { programmode = false; digitalWrite(LED_PIN, false); Serial.println(F("Program expired")); } } if ((timer % (200 / HEARTBEAT)) == 0 ) { // Look for new cards if ( !

Hi @BartE - thanks for putting this together! It has been very helpful.
I am working on a project with two wireless MFRC522 modules and RFID Reader. I want to be able to read PICC cards with the RFID reader and send it the UID between the modules. So essentially a more bare version of the code you have written with the garage door opening code. I was wondering if you could help me out in simplifying the code to just reading the UID off the PICC cards and outputting that date between the RCF522 modules.
Thanks in advance.

@codergirl56 there are a number of examples in the MFRC522 library which might help you.
You can find them here: https://github.com/miguelbalboa/rfidPlease feel free to ask questions if the examples does not help you further

@BartE thanks for getting back to me. I've looked through the examples on the MFRC522 library. I think the main thing I'm struggling with is setting up and initializing the N24L01 module and the RFID on the same arduino uno. My plan is to have one N24L01 and RFID on one arduino module, and a second N24L01 on a second arduino. I want the RFID to read the UID off of PICC cards and be able to wirelessly transmit the UID between the N24L01 modules. I think it's simpler than the code you have written here, but I'm struggling to simplify the code you have to only what I need. Could you possibly walk through what each function in your program is used for? Thanks in advance.

@SVLoneStar That should work, did you try the sketch shown in the topic?
The function recallEeprom(); reads the EEPROM content and after closing the program mode this function storeEeprom();
writes the EEPROM. Please add some debug info (Serial.print) and validate that these functions actually are called on- recallEeprom(); --> on start up
- storeEeprom(); --> ending program mode.
Hi BartE, I have the same issue regarding tags lost after power off. I run the debug instruction using Serial print as you mentioned. I found out that the storeEeprom line did not run after closing the program mode. I think this is why the tags are lost after power cycle.

@SVLoneStar That should work, did you try the sketch shown in the topic?
The function recallEeprom(); reads the EEPROM content and after closing the program mode this function storeEeprom();
writes the EEPROM. Please add some debug info (Serial.print) and validate that these functions actually are called on- recallEeprom(); --> on start up
- storeEeprom(); --> ending program mode.
I've just solved the issue regarding tags lost after power off.
Simply add the line "StoreEeprom();" after the program mode function
if (programmode && ((timer % (ONE_SEC / HEARTBEAT)) == 0 )) { ledon = !ledon; digitalWrite(LED_PIN, ledon); programTimer++; // Stop program mode after 20 sec inactivity if (programTimer > PROG_WAIT) { programmode = false; digitalWrite(LED_PIN, false); Serial.println(F("Program expired")); storeEeprom(); Serial.println(F("Store Card to EEPROM")); ```Raspberry Pi 2

Thx for analyzing this report. The fix you did made is not what i meant with program expired.
The idea is that you start program mode by pressing the program button and holding the master card.
And now one can add one or more new RFID cards and when your oke press the program button for a short period to END the program mode and store the new cards.If you wait too long the program mode will expire and the new cards are NOT stored. Off course you can change this behavior by adding this line as you suggested.

hello to all guys, I noticed some problems, if the power goes away there is a flaw in the system. I modified the source as needed to me, now you turn the sensor on domoticz when you turn on and off when you turn off. I modified the project to create an alarm homemade I configured via lua script the motion sensors. I mounted on the bell so as to turn on and off when I go out or within the home. thank you all

Hi Everyone,
I have tested this code http://etabetastudio.blogspot.it/2016/07/tutorial-lettore-rfid-rc522-arduino-idea.html to test RFID RC-522 with Arduino 2009 and all is ok, also to registred RFID card on EEPROM...
I hope to help uo...bye -
Dear All,
I'm a newbie and I found in MySensors website the project for RFID Lock Sensors that use PN532 RFID Reader, but as I already have with me a RC-522 RFID reader, searching on the forum I found this post that I thinked it will suit my case.
I assembled the various hardware parts as described on first post, but when I copied the sketch code in my arduino IDE, I'm not able to get it work.
I get some error message that is not so clear for me.
It's seems the sketch is for a previous version of MySensors Library or Arduino IDE, but I'm not sure of this.
As I use Arduino IDE 1.6.12 that has included MySensors Library 2.0.0, is the Sketch you included in the first post already valid for that setup ?
It' will be possible to have a valid sketch working with new setup or eventually to know how to proceed to make the actual one working ?
Thank you in advance for your attention.

It was written prior to the MySensors 2.0 update.You can convert pre- 2.0 sketches by following the instructions on https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x
If you need a hand just post here with your question, I'll try to help, but it's really not too bad once you get started. I'm in the process of converting all of my code to 2.0 as well.

@Rod-MacPherson
Dear Rod, thank you for the suggestion you gave me.
Following the instruction you indicated me, I was able to make the sketch working with new MySensors 2.0 library.Considering that I'm not a programmer, it was quite easy to make the sketch working.
Thank you again for your suggestion and off course thank you to BartE for the good original work he did.
If someone need new sketch working with library 2.0, feel free to ask me.
