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?

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...

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.

I tried your code for micropython but getting following error:
File "main.py", line 12, in RCtime
TypeError: can't convert str to int

Line 12 is as follows:
data = Pin(RCpin, mode=Pin.IN, pull=Pin.PULL_DOWN)

Not sure what happens here, any advice?

I would like to motorize door opening in greenhouse, based on inside temperature. Googled for similar project, but can not find one. Has anyone done some door opener? Was thinking of printing some angled rack and pinion that could be turned by stepper motor, which would be controlled by ESP32. The c...

Thank you valuable response. I intend to use ESP32 with sensors and relay switch conected to it. Micropyhon as SW. Node Red to check temp every 10min and, if below threshold, Node Red sends mqtt to switch on heater for 5 min. Intend to test prior bringing plants, as I do have monitoring of temp alre...

I intend to use KY-019 5V One 1 Channel Relay Module to switch on and off 2KW air heater. This is supposed to run during night, when sensors in my greenhouse would indicated that temp is below set threshold. It says it can handle up to 250V 10A, so seem to be not exceeding capabilities, but rather c...

Good point, but I have too many available inputs on ESP32, so thought will be easier to control and code it

I have made drawing for intended new PCB that will hold several sensors to monitor temperature at various locations of greenhouse and one switch that will control heater (when temperature drops below set during the night). I would appreciate your comments, suggestions on Additional elements like cap...

Thanks, I do have basic understanding from school, just like you described: (Like what is a resistor, what is a capacitor? Basic laws, like U = R * I and stuff like that?). I did also soldered several projects, but only following predefined set of components and layout. I have read about Fritzing an...
