I am using the Piromoni/blinkt/examples python files for a12v led strip light on my raspberry pi3. The leds are powered by a 12v power supply , and the pi3 is also powered by it’s correct power supply
When I run one of the files, say, solid_colours.py, it seems to run, but the leds don’t change colours or do anything else. With another file, rainbow.py I get this error message:
^CTraceback (most recent call last):
File “rainbow.py”, line 22, in
File “/usr/lib/python2.7/dist-packages/blinkt.py”, line 75, in show
File “/usr/lib/python2.7/dist-packages/blinkt.py”, line 41, in _write_byte
GPIO.output(DAT, byte & 0b10000000)
Then I looked in the blinkt.py it says:
DAT = 23
CLK = 24
What is that referring to, and does DAT mean data pin 23.
My 12v leds are connected to GPIO pins 17, 22 and 24, so do I edit the blinkt.py file and add the led pin numbers.
