Algorithm 4. Sending GPS values to Laser Pointer from drone:

GPS Algorithm: Transmits the drone’s GPS coordinates to the laser pointer, ensuring precise aiming and optimal communication path.

Input: Movements of the drone

Output: GPS values sent to the Raspberry Pi

1: define setup() function

2: begin Serial communication at 115200 baud rate

3: initialize GPS using gpsSerial.begin function with GPSBaud, SERIAL_8N1, pins 12 and 15

4: start Wi-Fi connection with WiFi.begin function using ssid and password

5: while Wi-Fi is not connected do

6: delay for 1000 ms

7: print “Connecting to Wi-Fi...” to the serial monitor

8: end while

9: print “Connected to Wi-Fi” to the serial monitor

10: end function

11: define loop() function

12: while gpsSerial has available data do

13: encode gpsSerial data using gps.encode function

14: if gps location is updated then do

15: create a WiFiClient object named client

16: if client is connected to the server at server_ip and server_port then do

17: define data as the string representation of gps location’s latitude and longitude, separated by a comma

18: send data to the server using client.println function
