I have not needed to use it and therefore in no position to advise you. I have read through Peter's tutorial in preparation for the day that I might need to use it. I think it would be fairly easy to do a simple application like yours. I would expect a simple example like yours in a tutorial. Stand...

I see I mis-understood your original posting. I thought that you could not get the LED to blink at all, but could get temp and humidity readings.

Sorry, for creating more confusion.

Its okay! No problem at all. Could you please let me assist how to use uasyncio to code for this? Thanking you.

Your code says to turn the LED on for 0.5 seconds and off for 3.5 seconds

Okay! Go it.

I have modify the code: from machine import Pin from time import sleep led = Pin(2, Pin.OUT) sensor = dht.DHT22(Pin(14)) while True: led.on() print('LED on') time.sleep(0.5) led.off() print('LED off') time.sleep(0.5) sensor.measure() print('Temperature = %.2f' % sensor.temperature()) print('Humidity...

OK about the IDE. I just use the command line so didn't recognise what was happening. So, back to my earlier comment about removing the DTH22 stuff and just focusing on getting the LED to work. from machine import Pin from time import sleep led = Pin(2, Pin.OUT) while True: led.on() print('LED on')...

Firstly, sorry I see you do call sensor.temperature() and sensor.humidity() It looks you have another file called main.py. Better post that as I don't understand: Ready to download this file,please wait! ... download ok exec(open('./main.py').read(),globals()) I understand that you want both of the...

I suggest to first try to understand why your simple bit of coding doesn't work. Does anything get printed out in repl when you use rshell? Does the LED blink? Comment out the lines: sensor.measure() print('Temperature = %.2f' % sensor.temperature()) print('Humidity = %.2f' % sensor.humidity()) sle...

The best way to achieve concurrency is to use uasyncio. In addition to the official docs I have written a tutorial which you may find helpful. There is a significant learning curve, but it's well worthwhile. Thank you for keep assisting. Gone through your provided "uasyncio" tutorial and found to b...

Using the code tags post the code you have. Are you trying to use uasyncio? Thank you for keep supporting. The code i am using: from machine import Pin from dht import DHT22 from time import sleep led = Pin(2, Pin.OUT) sensor = dht.DHT22(Pin(14)) while True: sensor.measure() print('Temperature = %....

I am learning Micropython codes on ESP32. I have learnt to code ESP32 how to blink an LED and measure Temperature and Humidity with DHT22 sensor with simple Micropython codes. Now i would like to combine these separate codes to blink an LED and measure sensor data at the same time within a code. I h...
