Tiny2040 is there an internal tempsensor like in PICO?

Which PIN ? Syntax similar as in PICO ?

Yes, use the same code:

import machine
import utime

sensor_temp = machine.ADC(4)
conversion_factor = 3.3 / (65535)
 
while True:
    reading = sensor_temp.read_u16() * conversion_factor
  
    temperature = 27 - (reading - 0.706)/0.001721
    print(temperature)
    utime.sleep(2)

It works but I’m not too sure about how accurate it is.

Thanks, yes it works. Shows temp around 29, Some LEDs are on ? why? I am new to Tiny so apparently I have tried something stupid. How can I turn LEDs off, all of them?

That is easy:

A little piece I wrote earlier. Just set r, g and b values as required.
