In this lesson, we will show how to use the OSOYOO IoT App to build a remote-controlled ambient light. You can change the light color at home through the mobile app to create more colorful moments.
Note: In the sketch, find the code at lines 13–14:
Replace *** with your Wi-Fi SSID and password:
char ssid[] = "***";//replace this line with your wifi ssid
char pass[] = "***"; //replace this line with your wifi password
Make sure to replace *** with your correct Wi-Fi SSID and password, or the project will not be able to connect to the internet.
Upload the sketch to the board and wait until you see the Arduino’s IP address.
Now open the OSOYOO IoT UDP App. (If you don’t have it, search for OSOYOO IoT UDP Robot App in the App Store or Google Play Store.)
Tap the Settings icon, enter the Arduino IP address as shown below, and tap Save.
Now you can change the LED color:
Press F1 to turn on RED; press F5 to turn it off.
Press F2 to turn on Green; press F6 to turn it off.
Press F3 to turn on Blue; press F7 to turn it off.
You can combine these 6 keys to create different colors.
