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.
If you haven’t install following libraries which are used in Lesson 1, please download and install them from following links:
Step 3) Open Arduino IDE: Choose corresponding board type and port type for you project.
Step 4) Arduino IDE: Click file – Open, then choose code in the folder, load up the sketch onto your Arduino.
In sketch file, replace *** with your wifi ssid/password
char ssid = "***";//replace this line with your wifi ssid char pass = "***"; //replace this line with your wifi password Upload the sketch to the board. Wait until you see something like this:
Open your serial monitor, you will see Arduino’s IP address as following:
APP Installation and Setting:
Step 1) If you haven’t installed OSOYOO IoT Robot APP, please search OSOYOO IoT Robot Car APP in Google Play or Apple Store to install this APP.
You read following tutorial link for more information about APP install :
Step 2):Make sure your Cell phone is in the same Local Network of Arduino. Open the APP, click Settings, enter your Arduino IP address from Step F and Port to 8888 in settings:
Line 40 defines the Cell phone APP’s IP address,
since we don’t know this LAN IP, so we use a default broadcasting IP 192.168.1.255. In this case, Arduino will send message to all devices in the Local network (192.168.1.xxx).
If we touch any key in the APP, Arduino will detect the IP address of your cell phone and use this IP to replace the broadcasting IP address 192.168.1.255. Since then, Arduino will only send message to your cell phone APP instead of broadcasting the message to all the devices in the LAN.
