Simple-fan.py doesn't work

[ktb92677]

Hi! I can't for the life of me get the simple-fan.py to work...

I have the black pin connected to pin number 26 per this diagram: https://www.google.com/search?q=raspberry+pi+3+b%2B+gpio+pinout&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiihcqXzrfjAhXVHM0KHeyEBhwQ_AUIECgB&biw=2560&bih=979#imgrc=D2ujNT7TNKinJM:.

And I have the red pin connected to pin number 25.

The fan does not turn on when the temperature gets high. But not only that it seems that a call to "GPIO.output(GPIOfan, True)" in general does not turn on the fan. Any help would be greatly appreciated!

Thank you for catching this. I apologize for wasting your time. I made a mistake. Red Fan pin goes to GPIO 3.3v. <<< My mistake (I wrote ground. It should be either pins 01 or 17) Black Fan pin goes to GPIO GPIO_PIN defined in the script, which is 26. So, this is correct. This steps below should allow you to see it turn on: $ sudo python

…
