Here's how this program works: 1. It imports the necessary libraries for Wi-Fi, MQTT, and GPIO control. 2. You need to set your Wi-Fi credentials (SSID and PASSWORD) and MQTT broker details (MQTT_BROKER, MQTT_PORT, and MQTT_TOPIC). 3. The `connect_wifi()` function connects the Pico W to your Wi-Fi network. 4. The `mqtt_callback()` function is called when a message is received. It prints the message and turns the LED on for one second. 5. In the `main()` function: - It connects to Wi-Fi and the MQTT broker. - It subscribes to the specified MQTT topic. - It enters a loop where it: - Blinks the LED briefly to show it's active. - Checks for MQTT messages using `client.check_msg()` (non-blocking). - Has a small delay to prevent tight looping. 6. If an error occurs, it will print the error message and disconnect from the MQTT broker. To use this program: 1. Replace `YourWiFiSSID` and `YourWiFiPassword` with your actual Wi-Fi credentials. 2. Set the MQTT_BROKER, MQTT_PORT, and MQTT_TOPIC as needed for your MQTT setup. 3. Save this script on your Raspberry Pi Pico W and run it. The onboard LED will blink rapidly to show the program is running and checking for messages. When a message is received on the subscribed topic, the LED will stay on for one second before resuming its blinking pattern.

The program runs the `main()` function when executed. To use this program: 1. Replace `"Your_WiFi_SSID"` and `"Your_WiFi_Password"` with your actual Wi-Fi credentials. 2. Replace `"broker.hivemq.com"` with your MQTT broker address if you're using a different broker. 3. Change `"your/topic"` to the MQTT topic you want to subscribe to. 4. Save this script on your Raspberry Pi Pico W Zero and run it. The onboard LED will blink rapidly to indicate that the program is running and checking for messages. When a message is received on the subscribed topic, the LED will stay on for 1 second before resuming its blinking pattern.

Before running this script, make sure to: 1. Replace `"Your_WiFi_SSID"` and `"Your_WiFi_Password"` with your actual Wi-Fi credentials. 2. Replace `"Your_MQTT_Broker_Address"` with the address of your MQTT broker. 3. Adjust the `MQTT_PORT` if your broker uses a different port. 4. Change `"your/topic"` to the MQTT topic you want to subscribe to. This script does the following: 1. Connects to your Wi-Fi network. 2. Connects to the MQTT broker and subscribes to the specified topic. 3. Enters a loop where it: - Toggles the LED state (blinking) - Checks for MQTT messages (non-blocking) - Waits for a short time (0.1 seconds) before the next iteration When an MQTT message is received, the callback function turns the LED on solid for one second, then turns it off. Make sure you have the `umqtt.simple` library installed on your Pico W. You can install it using Thonny or by copying the library files to your Pico W. This script provides a non-blocking way to check for MQTT messages while also giving you visual feedback through the LED that the script is running and receiving messages.

Before running this program, make sure to: 1. Replace `YOUR_WIFI_SSID` and `YOUR_WIFI_PASSWORD` with your actual Wi-Fi credentials. 2. Replace `YOUR_MQTT_BROKER_ADDRESS` with the address of your MQTT broker. 3. Replace `YOUR_MQTT_TOPIC` with the MQTT topic you want to subscribe to. 4. Install the `umqtt.simple` library on your Pico W if it's not already installed. This program does the following: 1. Connects to your Wi-Fi network. 2. Connects to the specified MQTT broker and subscribes to the specified topic. 3. Enters a loop where it: - Checks for MQTT messages without blocking (using `check_msg()`). - Blinks the onboard LED every 500ms to indicate it's running. - When an MQTT message is received, it prints the message and turns the LED on solid for 1 second. The LED will blink continuously to show that the program is running and checking for messages. When a message is received, the LED will stay on solid for 1 second before resuming its blinking pattern. Remember to handle any potential exceptions and reconnection logic for more robust operation in a real-world scenario.

This program does the following: 1. It imports necessary modules for Wi-Fi, MQTT, and GPIO control. 2. Sets up Wi-Fi and MQTT broker details (you need to replace these with your own). 3. Defines a function to connect to Wi-Fi. 4. Sets up an MQTT callback function that turns the LED on for a second when a message is received. 5. In the main loop: - Connects to Wi-Fi and MQTT broker. - Subscribes to the specified MQTT topic. - Continuously checks for MQTT messages without blocking. - Blinks the LED every 500ms to show it's polling. - When a message is received, the callback function is triggered, setting the LED solid for a second. To use this program: 1. Replace `"Your_WiFi_SSID"` and `"Your_WiFi_Password"` with your actual Wi-Fi credentials. 2. Update the `MQTT_BROKER` and `MQTT_TOPIC` if you're using a different broker or topic. 3. Make sure you have the `umqtt.simple` library installed on your Pico W. You can install it using Thonny or by copying the library files to your Pico W. 4. Save this script on your Raspberry Pi Pico W and run it. This script will continuously poll for MQTT messages while blinking the LED, and when a message is received, it will turn the LED on solid for a second before resuming the blinking pattern.
