Summary： In this project, we’ll create a status indicator PCB shield for the ESP32 featuring two rows of addressable RGB neopixel LEDs, a BME280 sensor, and a pushbutton. We’ll program the board to display a web server with the BME280 sensor readings and show the temperature and humidity range on the LEDs (like two progress bars). We’ll also set up a Wi-Fi Manager—the LEDs indicate whether it is already connected to a Wi-Fi network or if it is set in access point mode.
