Small #bathroom combined with a toilet is most often found in smart apartments. In this video, I will show how to make a smart drain for the toilet with my own hands, if there is absolutely no place for a drain tank or installation. The drain tank is controlled by the Arduino and the servo.


The cost was about $ 50 without the cost of a toilet.


Plastic drain tank - $ 23
Sewer Pipes and Connectors - $ 10
Arduino Nano Microcontroller - $ 4
6V 1A Power Supply - $ 4
Servo Towerpro MG996R - $ 6
Call button without fixing - $ 3
Connections - $ 2
