How to build an Arduino-based biometric voting machine
In this project, we’ll develop a biometric voting machine based on a person’s fingerprint. We’ll build the device using Arduino Mega, with a 3.5-inch TFT touchscreen and R307 fingerprint module. The touchscreen will be the user interface for the “voter” to cast their ballot.
