arduino_running_code

The code uploaded to the arduino, to be in use the majority of the time

• Outputs the (custom) UUID to Serial as cards are scanned
• Double beep -> error

write_tags

A utility to write UUIDs (integer, 0-2^32) to RFID tags

• User enters an initial ID number (ie 42) and the arduino writes identifiers in single increments from that as tags are scanned (first tag -> 42, second -> 43, etc)
• Writing "saints" to a sector alongside those is a WIP

main.py [intended to be put on a raspi and ran on boot]

Reads ids from arduino as scanned and processes them

• Reads the hex UUIDs outputted by arduino_running_code.ino in Serial, and writes the scan time (and associated id) to a csv
• Contains logic for distinguishing sign-ins and sign-outs
• correlates UUIDs to names, student ids, emails, etc and puts that in a "final" csv, to be sent off to the requisite target(s)

time.py [intented to be put on a raspi and ran on boot]

Sends a request to a time API and sets the raspi local time

• Intended for a network which blocks port 123 (used for NTP)
• Sends a request to the World Time API to get the current time
• Sets raspi time to the current time so that sign in times can be accurate

upload.py [intente to be put on a raspi and ran perioically]

Sends an email with the attendance csv attached

• Sends it to a single secified recipient
• Automates sending of the csv

web_server.py and HTML files [meant to be put on a raspi and ran on boot]

Runs a local web server (using Flask) which can be used to input attendance if someone forgets their RFID tag

• Stores attendance in the same file as the scanner code
• Can be used interchangebly with the RFID scanner
• The days attendance is viewable through another port on the raspi
• http:// (raspi ip adress):8000
• /admin shows attendance for the day
• /form is where you log in

Probably out of scope ideas

• Automate sending of csvs (will be using google drive api)
• Purchase and use a small screen attached to the pi to veriy that the process worked
• Have the pi host a small web server so that people without RFID tags can still sign in
