• Place the ESP32-CAM module on a breadboard for easy wiring.
• Connect its power pins to the battery pack or voltage regulator if required.

Prepare for Serial Communication:

• Connect GPIO 3 (TX) of the ESP32-CAM to GPIO 16 (RX) of the second ESP32.
• Connect both modules to a common ground.

Program the ESP32-CAM:

• Use a USB-to-serial adapter to upload the web server firmware to the ESP32-CAM.
• Test the video stream and web interface.

• Connect the motor driver input pins to four GPIO pins on the second ESP32.
• Connect the motor output terminals to the DC motors.
• Ensure the motor driver shares the same ground with the ESP32.

Connect the Servo Motor:

• Attach the servo motor to GPIO 12 of the second ESP32.
• Mount the servo motor to the panda box lid, ensuring smooth opening and closing.

Connect the Push Button:

• Wire the button to GPIO 13 and ground.
• Test the button functionality to trigger the panda box.

• Connect the battery pack to the motor driver and both ESP32 modules.
• Verify voltage levels to ensure compatibility with all components.

Common Ground:

• Ensure all components share a common ground for stable operation.

• Program the second ESP32 to interpret commands received via UART.
• Map commands (e.g., "Forward", "Left") to the motor driver and servo motor.
• Use non-blocking code (millis() instead of delay()) to maintain smooth operation.

Test Serial Communication:

• Verify that the second ESP32 receives and processes commands from the ESP32-CAM.

• Use screws, standoffs, or hot glue to fix all components securely to the chassis.

Organize Wiring:

• Use zip ties or heat shrink tubing to manage and protect wires.

Perform a Full System Test:

• Test motor movements, video streaming, and the panda box functionality.
