In summer of 2018, getting selected for GSoC internship and that too for FOSSASIA organization was a great oppurtunity for me. During this period I worked on Android app of Open Source Hardware platform Pocket Science Lab which enables school students, teachers, undergraduate to perform various experiments and study a wide range of phenomena.
FOSSASIA's Pocket Science Lab Android helps the user to exploit various functionalities like Oscilloscope, Waveform Generator, Programmable Voltage and Current Source, Sensor Data Logger, Multimeter etc of Pocket Science Lab hardware via Android Smartphone. It can also access the smartphone's in-built sensors to provide numerous sensor instrument like Lux meter, Accelerometer, Barometer etc. and can log data and export it to text file format like CSV from these sensor instruments using the Sensor Data Logger.

During the first month, I was given priority of developing the Wave Generator instrument from existing control advanced module, for which I developed the complete module from scratch having User Interface very similar to the physical wave generators present in the market for making it easier for the user to operate and implemented it's functionality to work with the PSLab device to produce different types of waveforms by connecting it to the communication module. I have also created the Device Screen activity for showing the PSLab device connection status and resolved some major bugs in the existing codebase.
In the second month, I have made some significant changes in the app to improve the User Interface of the overall app and I replaced the dialog box containing instrument guides by introducing Instruction Guides using Bottom Sheet for all the instruments which remain hidden at the bottom and can be viewed by swipe gestures. I also created Settings Activity to enable the user to modify the general settings or settings of specific instrument within the app.
In the third month, I worked extensively to revamp the Sensor Data Logging module by integrating the Realm Database with PSLab Android App for the storage of the recorded sensor data within the app and also implemented the GPS Logger for logging the location of the user along with the recorded sensor data. I created activities to visualize the stored sensor data in the form of graphs with logged location being shown on maps and created the functionality to export the recorded data in CSV format with some extra information like datetime, location and device information.

As the outcome, we were able to deliver a release quality Android app with revamped existing instruments, newly added sensor instruments, proper instruction guide for instruments, advanced sensor data logger along with major improvement in the UI/UX of the app.
