Documented Code

No code has been provided for the microcontrollers in the circuit. To fully utilize the ESP32 DEVKIT V1 and the DHT11 sensor, embedded code is required to initialize the microcontroller, read sensor data, control the LEDs, and manage power from the Lipo Battery. The code would typically be written in C or C++ using the ESP-IDF or Arduino framework and would include setup routines, main loops, interrupt service routines, and possibly power management functions.
