Summary

This circuit is designed to control multiple Brushless DC (BLDC) motors using Electronic Speed Controllers (ESCs), interfaced with an Arduino Nano microcontroller. The circuit includes a 12V battery as the power source, sensors like the MPU6050 accelerometer/gyroscope and HC-SR04 ultrasonic sensor for input, and a Neo 6M GPS module and Bluetooth HC-06 for communication. The Arduino Nano serves as the central processing unit, reading sensor data, controlling the ESCs, and communicating with external devices.
