LED Strip Example (SPI backend + WS2812)

This example demonstrates how to blink the WS2812 LED using the led_strip component.

How to Use Example

Hardware Required

• A development board with Espressif SoC
• A USB cable for Power supply and programming
• WS2812 LED strip

Configure the Example

Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>. Then assign the proper GPIO in the source file. If your led strip has multiple LEDs, don't forget update the number.

Build and Flash

Run idf.py -p PORT build flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
