In this lesson, we will use this IoT kit to remotely monitor the home environmental temperature and humidity, and display the data to the Blynk APP.
First, please plug OSOYOO MEGA-IoT Extension Board into MEGA2560 board:
Build the circuit as below:
Here we connect the signal pin (S) to digital pin D5.
Step 4 After installing above library, please download the code from following link, unzip it:
Step 5 After above operations are completed, connect OSOYOO MEGA2560 Board to PC with USB cable.
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.
Note: In the sketch, find these lines as following:
char auth =”YourAuthToken”;
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.
Upload the sketch to the board. Wait until you see something like this:
Congratulations! You are all ready! Your hardware is now connected to the Blynk cloud!
Open your project page and press the “+” button to add the “LCD” Widget.
Name Column: You can name your widget, whatever you like.
PIN V5, value: H
PIN V6, value: T
Here, you can try to change the LCD Widget to Labeled Value Widget by yourself, so that you can add the symbols of the corresponding data, but you need more Blynk energy.
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.
Now, you can see the temperature and humidity remotely!
If you find the device is offline, please check your code, wiring and app settings, and try again.
