Hey im trying to read the temperature and humidity from the AHT10 and im just stuck. I hook up the SCL an SDA with software ic2 and then i try to read on 0x38 and 0x39, 6 bytes.
The response is
[25,0,0,0,0,0]
And
[255,255,255,255,255,255]These vales doesn't change when i change the temperature. Whats the next thing i could try ?

I would love some code snippets ;)
They dont seem to provide the schematic directly but i bought this one
What i mean with the normal 3.3v pin is the pin that always just supplies 3.3v, i dont know how to target that pin through code. I will upload some videos of the application.

Thanks for your replies ! I did some investigation based on your answers and then it hit me.. I was driving the 3.3v side of the logic level shifter from Pin D25 with pinMode as 'input_pullup'.. bad idea. Moved it to normal 3.3 v pin. Now everything works smooth, first led works, dual strips.
Do you know why that was not working ? -
Hey so i got it to work thanks to the logic level shifter. But 2 other problem arose. I can't write to 2 different pins, which drives 2 different neopixel strips. Both are 9 leds long. Also cant seem to get the first LED lit up on either of the strips.
So once i write to 2 the API freezes and i need to reset the board before i can write to any again.
Im using pin D16 and D18

Alright, great stuff. Will go with a dedicated logic level shift circuit.
Well thank you all for your comments, you all made me realize it was doable hehe..
Here you go

Maybe i can improve some stuff, like could probaly make the user send in the i2c instance so it can be used with other devices on the same pins ?
