Introduction

In this lesson, we will show how to use the Osoyoo IoT Kit to build a RFID access control system. Before starting this lesson, you can get more information about the RFID module from this link.

HARDWARE

SOFTWARE

First, please plug OSOYOO MEGA-IoT Extension Board into MEGA2560 board:

Build the circuit as below:

RFID Module –  RFID Port

Please confirm whether the wiring is correct according to the VCC and GND pins

Step 1 Get your Blynk AuthToken

Step 2 Install latest Arduino IDE

Step 3 WifiEsp Library Installation

You also need to install the Servo library and RFID library as above operations.

Step 4 Servo Test

Before upload the code,  we should adjust the servo angle first. Please remove the items from the wooden house’s door area:

Then please download the servo test code from this link, unzip it:

https://osoyoo.com/driver/Smart_House_IoT_Learning_Kit_V2.0_code/servo_config.zip

Step 5 After above operations are completed, connect OSOYOO MEGA2560 Board to PC with USB cable.

Notice: Shut off your battery or unplug your power adapter when upload sketch code to Arduino.

Step 6 Open Arduino IDE:  Choose corresponding board type and port type for you project.

Step 7  Arduino IDE:  Click file – Open, then choose code in the folder, load up the  sketch onto your Arduino.

Upload the sketch to the board. Wait until you see something like this:

Done uploading

Step 8 After upload the code, the servo will turn to 0 degree position, now we install the wooden gear and the white fixed arm:

Step 9 Press the button, the door can be simulated to open, when released, the door can be simulated to close.

Step 10 After above operations are completed, please download the code from following link, unzip it, and follow the above Step 5 – Step 7 to upload the code:
https://osoyoo.com/driver/Smart_House_IoT_Learning_Kit_V2.0_code/lesson2-5.zip

You need to edit the code:

**********************************************************

Note: In the  sketch, find these lines as following:

char auth[] =”YourAuthToken”;

This is the Auth Token that you emailed yourself.(Step 1) Please check your email and copy it, then paste it inside the quotation marks.

It should look similar to this:

char auth[] = “f45626c103a94983b469637978b0c78a”;

Then find these lines:

char ssid[] = "******"; // your network SSID (name)
char pass[] = "******"; // your network password

please replace the ****** with your correct wifi SSID and password, otherwise your project can not connect to Internet.

**********************************************************

Add your own RFID Card ID:

After completing the above steps and uploading the code, open the IDE serial monitor, you can see that the system is initialized successfully, and then put your RFID card in the RDID module recognition area, you will see your serial monitor will display your The card information is as follows:

RFID START!
Find the card!
Card type: Unknown
The card's number is : 71BA2F2ECA

Then find these lines:

if( id[0]==0x32 && id[1]==0xDA && id[2]==0x94 && id[3]==0x10 ) 

And change the id data to your own card number,so the changed code is:

if( id[0]==0x71 && id[1]==0xBA && id[2]==0x2F && id[3]==0x2E ) 

In the same way, you can add or modify your card information at will, and finally, re-upload the code to the Arduino and continue the experiment.

**********************************************************

Upload the sketch to the board. Wait until you see something like this:

Done uploading

Congratulations! You are all ready! Your hardware is now connected to the Blynk cloud!

Add a Widget

Open your project page and press the “+” button to add  the “LCD” Widget.

Widget settings:

INPUT  ADVANCED
INPUT V11

After you finished all above operations, press the “ button. This will switch you from EDIT mode to PLAY mode where you can interact with the hardware.

While in PLAY mode, you won’t be able to drag or set up new widgets, press “” and get back to EDIT mode.

After you finished all above operations, approximate the RFID card or the keychain to the reader. Open the Serial Monitor and you will get some informations of the card. If you update your card information to the code, when you use the corresponding card, Let the reader and the tag closer , you will see that the corresponding name is printed in the serial monitor, and LED will be lit for a second.
