Numerical Method and Laboratory Experiment of RC Circuit using Raspberry Pi Microprocessor and Python Interface

摘要

RC circuit is the basic physics experiment show the charging and discharging on capacitor electronic component. In this paper, we have investigated the numerical simulation from the mathematical model of charging and discharging of capacitor, also we developed experimentally RC circuit using Raspberry Pi single board microprocessor and make interfaces using Python software. The benefit of this system that all of them was open Source and can help the physics experiment easily at the laboratory. To get data acquisition from RC circuit we used IC MCP3008 which have converted an analog to digital data. The experimental result showed the best agreement with the numerical simulation result.
