ประโยชน์ของโปรแกรม
…สามารถนำไปเป็นต้นแบบของลิฟท์ที่ใช้ภายในครัวเรือนขนาดเล็กโดยทั่วไป ข้อดีคือรูปแบบที่ใช้งานง่ายและระบบไม่มีความซับซ้อนมากอุปกรณ์ที่ใช้มีราคาถูก อีกทั้งยังสามารถนำไปติดตังกับลิฟท์ของอาคารทั่วไปหรืออาคารสำนักงานขนาดเล็กได้
อุปกรณ์ที่ใช้
1.ไมโครคอนโทรลเลอร์ PIC16F1939
2.มอเตอร์
3.เซเว่นเซกเมนต์ คอมมอนแคโทด
4.ทรานซีตเตอร์
5.แอลซีดีขนาด 16x2
6.ตัวต้านทาน 1000 โอห์ม
หลักการทำงานของโปรแกรม
…หลักการทำงานโดยทั่วไปคือผู้ใช้จะเป็นคนเลือกว่าผู้ใช้อยู่ที่ชั้นใดผู้ใช้ก็จะต้องกดฉันนั้น จากนั้นประตูลิฟท์ก็จะเปิดออกรอให้ผู้ใช้เข้าไปประตูลิฟท์ก็จะปิด หลังจากนั้นลิฟท์จะรอคำสั่งว่าผู้ใช้จะไปที่ชั้นใด สมมติว่าผู้ใช้อยู่ชั้นหนึ่งและต้องการจะขึ้นไปชั้นสองก็จะกดที่ชั้นสอง โปรแกรมก็จะสั่งให้มอเตอร์ของลิฟท์นั้นทำงานและขึ้นไปยังชั้นสองขณะที่ลิฟท์กำลังขั้นมอเตอร์กำลังหมุนก็จะมีเซเว่นเซกเมนต์บอกตำแหน่งว่า ลิฟท์ขณะนั้นด้วย
