Team Members & Responsibilities
- Uday Pratap Bais (20231267): Hardware Lead (Electrical), Design Lead.
- Yash Dadhwal (20231287): Software Lead (Algorithm), Testing, Software Integration.
- Yojit Kumar (20231289): Hardware Lead (Electronics), Documentation Lead.
Project Structure
- /docs: Contains all project documentation, including the report, component datasheets, and images.
- /hardware: Contains hardware design files (schematics, PCB layouts from KiCad).
- /src: Contains all Arduino source code, organized by testing phase.
- /dump: Put anything and everything we find before the finalizing of the project, It may later get sorted and moved to the relavant folders.
Getting Started
- Clone the repository:
git clone https://github.com/yojit-kumar/PH3144_ElectronicsProject - Install the required Arduino libraries:
EmonLibLiquidCrystal_I2CAdafruit_ADS1X15
- Use the calibiration codes in the
src/directory to calibirate the measurement components - Run the test codes from the same directory.

Questions
What parts does the AC Power Controller use?
20 parts, built around the BTA41-600BRG, ADS1115IDGS, MOC3023M and PC814. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AC Power Controller KiCad files?
From the yojit-kumar/PH3144_ElectronicsProject repository on GitHub, at the commit this page was made from: the board is hardware/AC_Power_Controller/AC_Power_Controller.kicad_pcb and its schematic hardware/AC_Power_Controller/AC_Power_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AC Power Controller design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
