Can't Control LED Strip over Pins (Solved) - Raspberry Pi Forums

hi,

followed tutorial: http://popoklopsi.github.io/raspberrypi-ledstrip/

when starting raspberry pi strips attached leds blue. after while dimmer , go out.
don't understand why, when touch lan or usb port go on again little while.

installed pigpio this:

wget abyz.co.uk/rpi/pigpio/pigpio.zip
unzip pigpio.zip
cd pigpio
make
sudo make install

when trying control leds nothing happens. commands using ones out of tutorial:

sudo pigpiod //for starting
pigs p 17 255
pigs p 22 128
pigs p 24 128

don't error or ouput, doesn't change anything.

don't know if can seen in pictures, tried. although i'm quiet sure wired correctly after checking multiple times:





know it's not easy assist this, maybe knows common mistakes or has tip check.

thank you!
best regards,

i don't see ground connection between of pi's ground pins, , source of fet's.
without not driving gates of fet's.
indeed common mistake, again @ example, , pin 6 of pi, black ground wire.
