Circuit Design Explanation

Power Supply

• The USB Type-C module provides a steady 5V supply.

• The AMS1117 voltage regulator steps down the 5V to 3.3V, ensuring the LEDs operate within safe limits.

• Capacitors (10μF and 0.1uF) are placed at the input and output of the voltage regulator to stabilize the current and voltage.

LED Circuit

• Six LEDs are connected in parallel to the 3.3V output of the regulator.

• Each LED is paired with a current-limiting resistor (330Ω or 470Ω)to prevent damage and ensure uniform brightness.

• You can add more LEDs by following the same setup for a brighter display!
