Smart Home Prototype Controlled by Smartphone With Reuse Waste Material
In this tutorial, we will make the smart home’s prototypes, we will use the reused waste material.
This smart home can control the lighting, sprinkler (we use the Submersible Water Pump), and may know the weather conditions, like will it rain or not, and the function will automatically control the shield of the clothesline. We can access all of the functions above only with the smartphone. For the application on the smartphone, we will make it with Android Studio, using prototype ESP8266 with Arduino IDE, and the communications between prototype and application use the Firebase

Make Prototype
- Make 4 holes at the corner of the cardboard
- Cut 2 ice cream’s stick into 2, and put it in to the corner of the cardboard
- Make 2 holes for the hanger
- Make 1 hole, and put in 1 ice cream’s stick that has been stick together with rain censor
- Cut the Clear Plastic Book Cover with arched shape
- Make 2 holes on the right & left sides for the hanger’s cover
- Put in 2 ice cream’s stick, then connect it with the glue that has been stick together with clear plastic book, cover the things that has been cut on the left sides
- Put in 2 ice cream’s stick, then stick the servo with masking tape together
- Then stick the ice cream’s stick together that has been glued with the right sides clear plastic book cover that has been cut and stick it together with servo
