Avoid code crash and exit

i do have a code that measures temperature from two sensors : DHT22 and DS1820. Both work fine until something happens. Either it does not receive reading back or get's response in a wrong format and then code crashes and exists. I do then restart ESP32 via reset button and all works fine again unti...

Controlling PC fan speed

I would like to control PC fan speed using ESP32 adn Micropython. Fan will be cooling air in my mini greenhouse, once temperature reaches trigger level, measured by DHT22. It is 12V fan and I can run it on 100% speed by connecting two power cables. However, there is no need to run it on 100% of spee...

Re: IR transmitter/receiver

Saw your video, thanks. Can you please share your github adress with code? Also, did you manage to program transmitter as well?

Re: IR transmitter/receiver

Find many solutions for Arduino, build one receiver on Arduino UNO and it works. Maybe that particular IR signal is easier to handle (think it is called NEC) ? Is there any reason that it is more difficult to implement on ESP32 with Micropython? Is it HW or SW that makes this implementation difficult?

Re: NEC Infrared receiver class

Haven't tried, thanks for sending link, will test out! Do you know if this also sends IR signal out? Or is it just receiver?

Re: NEC Infrared receiver class

Is this possible to read signal from remote controls laying around at home using your code MattMatic? I would like to read signal from AV receiver remote control, then use it with IR transmitter connected to ESP32 to automate AV receiver, so that I can for example turn on AV receiver using voice com...

IR transmitter/receiver

Is it possible to read IR signal from remote (any commercial remote control unit) using ESP32 and IR receiver, then reproduce that code using ESP32 and IR transmitter? Find many examples using Arduino, but didn't come across Micropython example.
