Write a python program that I can use to run on my raspberry pi pico w zero that will check for mqtt messages. Don't block, and blink the LED on every loop iteration so I know it's polling. When it gets a message then set the LED solid for a second.

Sure, I can help you with that. Here's a simple Python script that uses the `umqtt.simple` library for MQTT communication and `machine` library to control the onboard LED on a Raspberry Pi Pico W. Please note that you'll need to replace `'your_wifi_ssid'` and `'your_wifi_password'` with your actual WiFi credentials, and `'your_mqtt_broker'` with the address of your MQTT broker.

import time
import machine
import network
import umqtt.simple as mqtt

# Set up the onboard LED
led = machine.Pin(25, machine.Pin.OUT)

# Set up WiFi
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('your_wifi_ssid', 'your_wifi_password')
while not wlan.isconnected():
    time.sleep(1)

# Set up MQTT
mqtt_broker = 'your_mqtt_broker'
client_id = 'pico_w_zero'
topic = 'pico/message'

def on_message(topic, msg):
    print((topic, msg))
    led.value(1)  # Turn the LED on
    time.sleep(1)  # Wait for a second
    led.value(0)  # Turn the LED off

last_check = time.ticks_ms()
delta_check = 5000  # Check every 5 seconds

while True:
    try:
        mqtt.check_msg()
        if (time.ticks_ms() - last_check) > delta_check:
            last_check = time.ticks_ms()
            m = mqtt.MQTTClient(client_id, mqtt_broker, user="", password="")
            m.set_callback(on_message)
            m.connect()
            m.subscribe(topic)
            led.toggle()  # Blink the LED
    except OSError as e:
        print('Failed to connect to MQTT broker. Reason: ' + str(e))
        time.sleep(1)

This script will blink the LED on every loop iteration to indicate that it's polling for MQTT messages. When it receives a message on the subscribed topic, it will turn the LED on for a second.

Here's a simple Python program that you can use to check for MQTT messages on your Raspberry Pi Pico W Zero. This program uses the `umqtt.simple` library for MQTT and the `machine` library to control the onboard LED. Please note that you'll need to install the `umqtt.simple` library on your Raspberry Pi Pico W Zero before running this program.

import machine
import time
import umqtt.simple as mqtt

# Set up the onboard LED
led = machine.Pin(25, machine.Pin.OUT)

# MQTT broker settings
MQTT_Broker = "your_mqtt_broker"
MQTT_Port = 1883
MQTT_Topic = "your_mqtt_topic"

def blink_led():
    led.value(not led.value())

def on_message(topic, msg):
    print((topic, msg))
    led.value(1)  # Turn on the LED
    time.sleep(1)  # Wait for 1 second
    led.value(0)  # Turn off the LED

while True:
    try:
        mqtt.MQTTClient(MQTT_Broker, MQTT_Port, keepalive=3600).connect()
        print("Connected to MQTT Broker")
        mqtt.MQTTClient(MQTT_Broker, MQTT_Port).subscribe(MQTT_Topic)
        print("Subscribed to topic: ", MQTT_Topic)

        while True:
            blink_led()  # Blink the LED on every loop iteration
            time.sleep(0.1)  # Wait for 0.1 second
            mqtt.MQTTClient(MQTT_Broker, MQTT_Port).wait_msg()
            if mqtt.MQTTClient(MQTT_Broker, MQTT_Port).check_msg():
                on_message(mqtt.MQTTClient(MQTT_Broker, MQTT_Port).get_attr("topic"), mqtt.MQTTClient(MQTT_Broker, MQTT_Port).get_attr("data"))

    except Exception as e:
        print("Failed to connect to MQTT Broker. Error: ", e)
        time.sleep(5)  # Wait for 5 seconds before retrying

Please replace `"your_mqtt_broker"` with the address of your MQTT broker, and `"your_mqtt_topic"` with the MQTT topic that you want to subscribe to. This program will connect to the MQTT broker and subscribe to the specified topic. It will then blink the onboard LED on every loop iteration to indicate that it's polling for messages. When it receives a message, it will turn on the LED for 1 second before turning it off again.

Sure, here's a simple Python script using the `umqtt.simple` library for MQTT, which is a lightweight MQTT library suitable for microcontrollers like the Raspberry Pi Pico. For the LED blinking, I'm assuming you have an LED connected to GPIO pin 25. Please note that you'll need to replace `<MQTT_BROKER>`, `<SUBSCRIPTION_TOPIC>`, `<CLIENT_ID>`, `<USERNAME>`, and `<PASSWORD>` with your actual MQTT broker address, subscription topic, client ID, username, and password respectively.

import machine
import time
import umqtt.simple as mqtt

# LED setup
led = machine.Pin(25, machine.Pin.OUT)

# MQTT setup
MQTT_BROKER = "<MQTT_BROKER>"
SUBSCRIPTION_TOPIC = "<SUBSCRIPTION_TOPIC>"
CLIENT_ID = "<CLIENT_ID>"
USERNAME = "<USERNAME>"
PASSWORD = "<PASSWORD>"

def on_message(topic, msg):
    print((topic, msg))
    led.value(1)  # Turn the LED on
    time.sleep(1)  # Wait for a second
    led.value(0)  # Turn the LED off

mqtt.subscribe(SUBSCRIPTION_TOPIC, on_message)

while True:
    mqtt.check_msg()  # Non-blocking check for MQTT messages
    led.value(not led.value())  # Toggle the LED state
    time.sleep(0.1)  # Wait for a short period before the next loop iteration

This script will subscribe to the specified MQTT topic and blink the LED on every loop iteration. When a message is received, it will turn the LED on for a second. Please note that you'll need to have the `umqtt.simple` library installed on your Raspberry Pi Pico. If it's not, you can install it using the Thonny IDE or by manually copying the library to the Pico's file system. Also, this script uses a simple, unsecured MQTT connection. If you need to use MQTT over TLS/SSL, you'll need to use a different library, as `umqtt.simple` does not support it.

        print('MQTT error:', e)
        led.off()  # Turn the LED off on error
        time.sleep(1)  # Wait for a bit before the next iteration

This script will connect to your WiFi, then to your MQTT broker. It will subscribe to the specified topic and call the `on_message` function whenever a message is received. The onboard LED will blink on each loop iteration and will turn on for a second when a message is received.
