Tripwire Automatically Minimizes Your Tabs When Someone Walks By

Do you always slack off on your computer and worry about getting busted? Not anymore because today we are going to make a Tripwire which automatically minimizes your tabs when someone walks by.


Before we going to the project let me thanks for sponsoring this project.

ALLPCB is an ultrafast PCB super factory as well as an Internet-based manufacturing company. We are committed to building an electronic collaborative manufacturing service platform. We serve enterprises related to consumer electronics, communication equipment, industrial control, instruments and apparatus, intelligent hardware, “Internet of Things” and “Industry 4.0” solutions, etc. We offer professional one-stop service, including PCB manufacturing, PCB assembly and components sourcing.


This project mainly contains two modules RECEIVER (Rx) and a TRANSMITTER (Tx). The Rx module is the one which we connect to the computer’s USB port which will receive a signal to execute the pre-written script whenever there is a trigger happens in the Tx module.
