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.

HARDWARE

SOFTWARE

In above example, 192.168.1.81 is the IP address of my IDE, we need to set this IP address in our APP in next step.

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:

Code Explanation:
Line 40 defines the Cell phone APP’s IP address,

IPAddress phoneIP=IPAddress(192,168,1,255);

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.
