a software simulation to design a 7 segment display system using LED lights

this is one of the basic simulation based systems for project designers who are interested to know about Arduino micro-controller based control systems along with learning to know how user-friendly it is before making any hardware projects. You can set your own conditions in the visual designer by means of flowchart and redesign your system easily . In this simulation, a 7 segment display is used to display 15 alphabets sequencially . Timer functions are also included along count sequence. Software simulations can be helpful to build basic knowledge about different systems and utilizing the gained knowledge for future projects. you can use your own customized conditions as decision criteria for playing with your own project too-which is fun at times ! specially in pandemic situation, as going out for buying hardware components may mean violating safety measurements in some of countries - so students can utilize their time by learning simulations and yet complete their projects using proteus software and their flowchart ideas.
