| dc.description.abstract | The development of technology maximizes the performance of existing technology to ease human work in everyday life. To control the curtains, a smartphone with Android operating system is needed. The smartphone is used as a command giver to the curtains through blynk which is the processor connected to the stepper motor as the mechanical drive of the curtains. To design and make a curtain control system tool that can be accessed via a smartphone, several important components are needed in the form of NodeMCU ESP8266, stepper motor and motor driver. The design of this tool is carried out with several tests in stages starting with testing the voltage source circuit, NodeMCU microcontroller, stepper motor testing, NodeMCU ESP8266 testing, LM2596 IC testing (Stepdown Regulator) and Joystick testing on the Blynk platform. Controlling the curtain through smartphone can be done by connecting the component circuit with joystick on Blynk platform requires WiFi. This tool is very easy for users to do curtains remotely, for example when outside the house, users can close the curtains only by using a smartphone. Users also do not need to spend energy to open or close the curtains both inside and outside the house. | en_US |
