In this lesson, we will show how to use the OSOYOO IoT kit and  Blynk APP to make a remote-controllable ambient light. We can change   colors of the light at home through the mobile APP to make more colorful moments.

HARDWARE

SOFTWARE

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

RGB  module — RGB port

Prerequisite:
You need to install Local Blynk Server, Blynk APP, Arduino IDE, Blynk Libraries before running the code of this lesson. If you haven’t done these installations, please read following contents in lesson2-1 link:

https://osoyoo.com/2021/04/29/osoyoo-smart-home-iot-blynk-lesson-2-1-simple-control/#prerequisite

If you have installed above libraries, please go to next stage:
Download and Edit Lesson2-8 Arduino Code
Step 1 Download the code from following link, unzip it:
https://osoyoo.com/driver/Smart_House_IoT_Learning_Kit_V2.0_code/Lesson2-8.zip

Step 2 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 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.

You need to edit the code as following:

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

Note: In the  sketch, find these code in line 13,14 as following:

char auth[] =”0ByWpc50cmOJ5O6OyHMaK4OSHkDvUeI-”;
char server_ip[]=”192.168.1.81″; // replace this line with your Blynk Server IP addres;

Replace 0ByWpc50cmOJ5O6OyHMaK4OSHkDvUeI- with your local Blynk Token.
Replace 192.168.1.81 with your local Blynk Server LAN IP address.
If you don’t know how to get token and Server IP address, read this article.

In   lines 18,19 and replace *** with your wifi ssid/password

char ssid[] = "***";//replace this line with your wifi ssid
char pass[] = "***"; //replace this line with your wifi 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:

Done uploading

Now open your Serial Monitor, you will see Arduino is trying to talk to Blynk server. After 20 to 30 seconds, your Serial monitor will finally shows Arduino’s IP address and a “Ready (ping: 25ms)” ending message.

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

Add a Widget in Blynk legacy APP

Open the Blynk APP , Follow the next operations:

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

zeRGBa Widget settings:

Name Column: You can name your widget, whatever you like.

INPUT: V7

Select the “MERGE” output mode

Then back to the project page. and press the “▷” button to start your project.

Slide the floating button on the zeRGBA widget, you can see that the lighting at home changes with your settings, so that you can control the color and brightness of the lighting at home at will.

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

If you find the device is offline, please check your code, wiring and app settings, and try again.
