Intelligent curtain control system based on
single-chip ATMega328P
Abstract
The purpose of this project is to develop an intelligent control system based on ATMega328P
microcontroller, with commonly-seen shutters as hardware platform, using 28BYJ48 four phase five
wire stepper motor integrated with ULN2003 Darlington arrays as driver section. With the
collection of light intensity by photosensitive sensor, followed by sampling / holding circuit, AD
conversion circuit, the system will give a digital output. Next, the signal will compare with preset
parameters, and use the positive and the negative output signal to control the motor in order to
achieve the purpose of opening and closing the curtains. At the same time using the matrix
keyboard to achieve manual open and close of curtains and set the function of opening and closing
coefficient.
