Inspiration
Finding good and reliable IoT solutions to everyday problems is occurs often, at any day, at any time. This IoT proof-of-concept project aims to eliminate paper sign-ins and attendance quizzes, will providing the course professor with a good snapshot of overall attendance behaviors.
What it does
An RFID chip is tapped to an RFID reader that determines if a student is enrolled in the course, marks them as "Checked-In". Tapped again, and seeing that the student is "Checked-In", they will then be marked as "Check-Out".
How I built it
Made use of an Arduino UNO, an LCD-1602, and the RC522 RFID module.
Challenges I ran into
Some confusion encountered on the interpretation of some the functions provided within the 'LiquidCrystal' library for the LCD-1602 LCD screen.
Accomplishments that I'm proud of
First project making use of the Arduino UNO development kit.
What I learned
The manipulation of read bytes from an RFID chip, and its functionality.
What's next for RFID Attendance IoT
Implementation of NodeMCU, which is an open-sourced firmware based on the ESP8266 WiFi SoC, aimed towards IoT prototyping and development.
