| # LED RGB | |
| ## Project Description | |
| This is a simple ESP32 project that turns on an RGB LED. | |
| ## Hardware Components | |
| - ESP32 DevKit v1 | |
| - RGB LED | |
| - 220Ω resistor * 3 | |
| ## Circuit Description | |
| The R, G, B pin of the RGB LED is connected to the pin5, pin4, pin2 pin of the ESP32 through a 220Ω current-limiting resistor. The common pin of the RGB LED is connected to 3V3. | |
| ## Expected Behavior | |
| When the ESP32 powers up, it should: | |
| 1. Set pin5, pin4, pin2 pin mode to OUTPUT | |
| 2. Considering that the LED's common pin is connected to 3V3, turn on only the blue segment at full brightness. | |
| ## Success Criteria | |
| The test is successful when: | |
| 1. Only the blue light of the RGB LED is fully on. | |
| ## Notes for Implementation | |
| - Use Arduino.h library for arduino core. | |
| - The LED should turn on immediately during setup and stay on | |
| - No actions are required in the loop function | |
| - The pin number used should match the circuit diagram | |
| ## Variants | |
| This project may have different variants with the RGB LED connected to different pins. | |
| ## Attributes | |
| - To use 220Ω resistor, set the property name "value" to "220 ohm". |
