ESP32 LED Chaser
The ESP32 LED Chaser project demonstrates how to create a sequence of LEDs that light up and turn off in a chasing pattern using an ESP32 microcontroller. LED chasers are visually appealing and can be used for decorative purposes or as indicators in various applications.
Components Needed
- ESP32 Microcontroller
- LEDs (number depends on your design)
- Resistors (if necessary)
- Jumper Wires
- Breadboard (optional)
Circuit Setup
Connecting LEDs to ESP32:
Connect each LED's anode (longer leg) to individual GPIO pins on the ESP32 (e.g., GPIO 2, GPIO 3, GPIO 4, GPIO 5, GPIO 6).
Connect each LED's cathode (shorter leg) to ground through a current-limiting resistor (if necessary).
Instructions
setup:
Define the number of LEDs (
Initialize each GPIO pin in the

After turning on each LED, introduce a delay (
Turn off each LED immediately after turning it on to create the chasing effect.
Repeat the sequence in reverse order to make the LEDs appear as though they are chasing each other.
considerations:
LED Configuration: Ensure correct polarity (anode to GPIO, cathode to ground).
Current Limiting: Use resistors if required to limit current through the LEDs.
Power Supply: Ensure the ESP32 has adequate power supply to drive multiple LEDs simultaneously.
