🔒Secure LED brightness control using Arduino UNO, password auth, and potentiometer input.
A simple yet effective Arduino project that combines basic embedded security and analog control. Users must enter a correct password via the Serial Monitor to unlock access to an LED whose brightness is then controlled by a potentiometer.
Features:
Serial-based password authentication
LED brightness control using a potentiometer
Ideal for learning about embedded systems, input/output interfacing, and basic access control
Components Used:
Arduino Uno
1x LED
1x Potentiometer (100kΩ)
1x 220Ω resistor
Jumper wires and breadboard
