Hello friends, I hope you all are doing well. In today's tutorial, we are going to design a Home Security System using Arduino UNO in Proteus software. It's the most commonly designed engineering project, especially in electrical, electronics and mechatronics engineering. Normally engineering students design it as a semester project during their engineering course. So, today we will design a home security system from scratch in Proteus software. I have given the complete project below to download but I would suggest you to design it on your own so that you could understand it better. So, let's get started: Libraries Libraries used in this project Arduino Library for Proteus: V2.0 (2021, used in this project) · latest version: V4.0 (October 2026) Flame Sensor Library for Proteus: V1.0 (2016 ...
