File Guide

android_app

• android app file (java)
• save data for json in app & visualization to graphs (pie / bar)
• save personal data (user input) to calculate kilocalories & recommended sugar

arduino

• hardware code (arduino / c / cpp)
• uploaded to ATTiny1614 Microcontroller (with jtag2updi by ElTangas + megaTinyCore by SpenceKonde)
• saves sensor output (RGB data + IR data + GyroSensor data) in binary buffer and send it by bluetooth connection (HC-06)

matlab

• matlab code (.m)
• it is generated for plotting binary RGB data to 3-axis scatter graph
• (used for data qualification & visualizing for presentation)

python

binwatchtest

• this file is the main file used for this project (PC Server)
• it watches certain folder for whether new file is generated (sent by android app) or not
• if new file detected, binkeras_load or binkeras function called

binkeras

• this file is called when new file's name is <beverage_name_here>.bin (ex: coke.bin)
• train all the data inside the folder (except temp.bin)
• if there's coke_1.bin and coke_2.bin, those data is both trained as label 'coke' (for multiple data in each beverage label)
• and save keras model data + weight in the folder (for further usage!)

binkeras_load

• this file is called when new file's name is temp.bin
• it classifies the beverage name by binary data in temp.bin (sensor output obtained by hardware, RGB + IR)
• saved model data + weight is loaded

binread & binwatch

• py files for test (prototype - not for actual usage)
