Think i capped it, did notice a few times the leds seem to flicker just to say visible but very fast, plugged the arduino on battery power noticed they stopped flickering then pluged it back in to the psu that also drive the white leds flickering again, so got a 12v 5 amp psu linked neutrals dc-dc converter to 7v and touch wood all seems fine, another thing i did notice i removed the ground wire from the heatsinks and the leds lit up ever so slightly only went back off when i re-attached the neutral again

Had the arduino run though the day night cycle around 30 times and all seems fine so far so good

For some reason the 36v 11 amp psu that runs the whites also runs the arduino via dc-dc converter, the leds flicker when been ramped up or down by the arduino, i shoved another arduino set up on using battery no flickering so fault had to with that psu or dc-dc converter, i just put the arduino on its own psu and linked the neutrals no flickering.

Cost me another 3 drivers today sorting that lot out glad there sending me some free ones lol

If it's just the two channels giving you problems, maybe you could benefit from using the ICL7667 dual mosfet, the same that is used in Krusduino in between the Arduino and the drivers. Just a suggestion since you may already have one on hand. Easy hookup with the pwm pins passing through, 5V, and GND.

Hello, I just got the "PWM Fan" and not as plugging. Red and black would understand that positive and negative, but as I connect the yellow and blue wires? Best Regards

You only have to connect the blue one, is the PWM wire. Just cut the yellow or not connect it.

Yep, yellow is the tachometer. Leave it disconnected.

After spending 5hrs attaching pins, I can confirm that the earlier mentioned screen extension (screen and shield extended together) is working at a length of 700mm away!
Tomorrow i'll fit it to my aquarium controller.

Well Done! I can sense your relief.  Good luck mounting it in its final position tomorrow.  Mine is still behaving perfectly after adopting this approach.

Thanks for sharing in the first place!
It would seem that the voltage must be higher pre-shield compared to that between the shield and screen so less losses in the cable.

After much trial and error (on my part) I finally have a working version of the Jarduino!  :whoo: I'm not sure if this was already covered... but is there any way to edit the colors in the sketch? I was trying to modify the sketch, but I don't think I'm editing the right lines or maybe enough of the right lines.
Thanks,  Michael

There's currently no easy way to change them, but I plan on adding the ability to pick up to six customisable colors.
