Development of atmel microcontroller based automatic sliding door

Abstract

This research was designed for one door-room installation, primarily to level up the automation design capacity of TUP in developing quality, and significantly affordable automatic sliding doors. It was made of the latest technology in embedded applications such as the Atmel Atmega 328 AVR mini microcontroller, C++ programming language with Arduino 1.5.7 IDE, Passive Infrared (PIR) Sensors, manual override pushbutton switches, limit switches, geared DC motor, high current power supply and its backup, sprocket-pulley system, and manual lock system. It utilized locally available materials, and had gone through extensive testing procedures. The unit was designed for approximately 2 semesters by using the Input-Process-Output (IPO) model, stress tested for at least 50 hours, and evaluated by 20 respondents, 2 faculty members, 3 industry experts, and 15 students. Based on the 5-point criteria evaluation system, the study concluded that the project was very functional ( = 4.50); highly aesthetic (=4.53); highly workable ( = 4.63); very durable ( = 4.50); highly economical ( =4.60); highly safe ( = 4.60), and overall rated as highly acceptable ( = 4.56).
