In this paper, we describe the m-learning platform ControlDroid, which allows the students to design and implement SISO control systems with their smartphones or tablets. The platform is composed by an application in Android and a development board to connect sensors and actuators for the control system. Regarding the application, the digital classic controllers (P, PI, PID) are built using the Google visual Tool Btockly that simplifies their implementation, focusing the attention of the students in the aspects of plant identification, simulation and design, instead of the algorithms needed in the implementation of a controller. To test the platform, we perform an experiment to control the velocity ω of the DC motor (EMG30) and we expose the respective results in the manuscript. The concept of the platform represents a curricular transformation in the area of control systems, taking the advantage of the mobile devices and offering the possibility to the students learn control systems in their homes without an expensive infrastructure, aspect that takes more relevance given the current challenges of the education in the COVID-19 pandemic.
