In this video lesson I show how to get usable Latitude and Longitude from the Adafruit Ultimate GPS version 3 using the Raspberry Pi Pico W. We read the NMEA sentences from the GPS, we parse them into individual strings for each sentence, and then we create arrays of data from the strings. Then we begin to parse the arrays, and convert the confusing numbers into useful Decimal Degree values for Latitude and Longitude.

Controlling Brightness of Arduino LED Remotely Using PyQt and WiFi

June 25, 2025 admin

In this lesson we will use PyQt5, UDP and WiFi to control the brightness of an Arduino LED circuit remotely. The PyQt generates a constantly updating sin wave, which it plots on a PyQt graph, and then transfers the brightness in real time to the arduino project. This lesson teaches many important skills including UDP, WiFi, PyQt5, Python, Arduino and LEDs.

When using the breadvolt, or any battery power supply on a breadboard project, do not turn the power supply on while the Arduino is connected to USB, as you could generate voltage conflicts. It is an either or. If the USB is connected, the power supply should be OFF. The schematic for the arduino circuit is shown below:

Schematic of our Arduino Uno R4 Wifi connected to an RGB LED

In the video, we develop code for the server, on the arduino, and the client, running in Python on the desktop. We present the code below for your convenience.

This is the Server code for the Arduino:

#include <WiFiS3.h>
#include "secrets.h"
WiFiUDP udp;
int PORT = 12345;
String myString;
String stringArray[10];
String response = "ACK";
int redPin=9;
void setup() {
  Serial.begin(9600);
  pinMode(redPin,OUTPUT);
  Serial.print("Connecting to ");
  Serial.println(mySSID);
  WiFi.begin(mySSID, myPASS);
  while (WiFi.status() != WL_CONNECTED) {
    delay(100);
    Serial.print(".");
  }
  Serial.println("\nConnected to WiFi");
  Serial.println(WiFi.localIP());
  udp.begin(PORT);
  Serial.print("UDP Server started on port ");
  Serial.print(PORT);
  // put your setup code here, to run once:
}
void splitString() {
  int startIndex = 0;
  int indexCount = 0;
  int i;
  int j;
  myString = myString + ':';
  for (i = 0; i < myString.length(); i = i + 1) {
    if (myString[i] == ':') {
      stringArray[indexCount] = myString.substring(startIndex, i);
      indexCount = indexCount + 1;
      startIndex = i + 1;
    }
  }
}

void loop() {
  // put your main code here, to run repeatedly:
  if (udp.parsePacket()) {
    myString = udp.readStringUntil('\n');
    splitString();
    analogWrite(redPin,stringArray[0].toInt());
  }
}

#include <WiFiS3.h>

#include "secrets.h"

WiFiUDP udp;

int PORT = 12345;

String myString;

String stringArray[10];

String response = "ACK";

int redPin=9;

void setup() {

Serial.begin(9600);

pinMode(redPin,OUTPUT);

Serial.print("Connecting to ");

Serial.println(mySSID);

WiFi.begin(mySSID, myPASS);

while (WiFi.status() != WL_CONNECTED) {

delay(100);

Serial.print(".");

}

Serial.println("\nConnected to WiFi");

Serial.println(WiFi.localIP());

udp.begin(PORT);

Serial.print("UDP Server started on port ");

Serial.print(PORT);

// put your setup code here, to run once:

}

void splitString() {

int startIndex = 0;

int indexCount = 0;

int i;

int j;

myString = myString + ':';

for (i = 0; i < myString.length(); i = i + 1) {

if (myString[i] == ':') {

stringArray[indexCount] = myString.substring(startIndex, i);

indexCount = indexCount + 1;

startIndex = i + 1;

}

void loop() {

// put your main code here, to run repeatedly:

if (udp.parsePacket()) {

myString = udp.readStringUntil('\n');

splitString();

analogWrite(redPin,stringArray[0].toInt());

}

You will need to open a new tab, and save the following code as “secrets.h” with the program above.

#define mySSID "Your WiFi Name"
#define myPASS "Your WiFi Password"

1 2	#define mySSID "Your WiFi Name" #define myPASS "Your WiFi Password"

Connecting the Adafruit Ultimate GPS to the Raspberry Pi Pico W

June 9, 2025 admin

In this video lesson we will connect the Adafruit Ultimate GPS to the Raspberry Pi Pico W, and will write a simple program to capture the data being sent by the GPS. In this lesson, we simply want to read and print the NMEA sentences coming off the GPS, and then in future lessons we will begin to parse the data, and turn the data into usable numbers. This is the schematic for connecting the GPS to your Raspberry Pi Pico W.

Then this is the simple code we developed to allow reading the data coming from the GPS.

from machine import Pin,I2C,UART  #***************
import time

GPS = UART(1, baudrate=9600, tx=machine.Pin(8), rx=machine.Pin(9))
# The following line ensures that the GPS reports the GPVTG NMEA Sentence
GPS.write(b"$PMTK314,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0*28\r\n")
try:
    while True:
        if GPS.any():
            #myChar=GPS.read(1)
            myChar=GPS.read(1).decode('utf-8')
            print(myChar, end="") #Supress the line feed, so It continues to print across
except KeyboardInterrupt:
    print("\nStopping program... Cleaning up UART.")
    GPS.deinit()  # Properly release UART before exit
    time.sleep(1)  # Short pause to ensure clean shutdown
    print("Exited cleanly.")

from machine import Pin,I2C,UART #***************

import time

GPS = UART(1, baudrate=9600, tx=machine.Pin(8), rx=machine.Pin(9))

# The following line ensures that the GPS reports the GPVTG NMEA Sentence

GPS.write(b"$PMTK314,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0*28\r\n")

try:

while True:

if GPS.any():

#myChar=GPS.read(1)

myChar=GPS.read(1).decode('utf-8')

print(myChar, end="") #Supress the line feed, so It continues to print across

except KeyboardInterrupt:

print("\nStopping program... Cleaning up UART.")

GPS.deinit() # Properly release UART before exit

time.sleep(1) # Short pause to ensure clean shutdown

print("Exited cleanly.")
