Here's a description of the wiring in the circuit diagram: Power Connections: The VCC pin of the DFPlayer Mini is connected to the 5V pin of the Arduino.; The GND pin of the DFPlayer Mini is connected to the GND pin of the Arduino.; Communication Connections: The RX pin of the DFPlayer Mini is connected to Arduino's D11 pin via a 1kΩ resistor (to protect the module from higher logic levels). The ESP32 controls two LEDs (green and red) and reads an analog value from a potentiometer.
