Instructions: 1. First, open the Arduino IDE and write the pins you will use in the variables called PINES (Lines 80-110) in the program. 2. Calibrate the Servomotors by setting the angle that corresponds to a straight position using the variables VCA, VCB, VCD, and VCE. Adjust the values to be around 90 degrees (Lines 130-135) in the program. 3. Select your LED type: Negative or Positive common (Line 139) in the program. If Negative, choose 1 or 2; if Positive, select accordingly. 4. Install the drivers for the Chinese Arduino Nano if necessary. 5. Choose the board (Arduino Nano), processor (ATmega328), and port from the Tools menu. If you're unsure, open Device Manager in Control Panel and search for the Arduino to find the correct COM port number, such as COM3. 6. Once ready, upload the program by connecting the board and clicking Upload or pressing Ctrl+U. Building Materials: * 3D Printed Pieces * Arduino Nano ($3) - available online * Expansion Board ($1) - buy online * 4 SG90 Servos ($6) - purchase from an internet retailer * HC-06 Bluetooth Module ($3) - buy online * HC-SR04 ($1) - available on the internet * Buzzer ($1) - you will need to buy five, as they are typically sold in sets * RGB LED ($1) - purchase ten, as individual LEDs are not widely available
