Schematic Diagram

The WS2812 LED strip is composed of a series of individual LEDs that can be programmed to display different colors and patterns. In this project, the strip is set up to display a running light that moves in a particular direction and changes direction when an obstacle is detected by the obstacle avoidance module.

• You can open the file 6.2_flowing_led.ino under the path of esp32-starter-kit-main\c\codes\6.2_flowing_led directly.

• Or copy this code into Arduino IDE.

This project extends the functionality of the 2.7 RGB LED Strip project by adding the ability to display random colors on the LED strip. Additionally, an obstacle avoidance module has been included to dynamically change the direction of the running light.
