In this project , we control seven segment display counter through 3 ways : hardware ( push buttons and IR sensors ) ,mobile application and web application . The project based on ESP32 with micro python firmware and code is written with python . Web application is connected with program using socket module . Push buttons and IR sensors are connected to pins with interrupt listener so we can control with buttons although socket blocking . We use IR sensors to control through hardware without touching . Mobile application is made using MIT inventor and control counter through accessing the web application in a hidden web browser included . Web application and mobile application can synchronize with each other and hardware by clicking refresh button on web and mobile app .
