Use a multiple dimmer? like 8 Channel AC Light Dimmer

[04greg1980]

Hello I would like to know if it's possible to use a "8 Channel AC Light Dimmer Module Arduino"
to control and dimmering led spot.

Do you have some ideas about the code I need use to use it?

Thanks a lot

Not sure what protocol this board uses.

Seems you need to detect interrupts on each channel and do pin on/off. This is not possible with Z-Uno. In future Z-Uno will be able to track one interrupt.

Hello,
Thanks for your answer. I have found an example of sketch to use this 8 channel AC light Dimmer with arduino. Do you have an idea if the compatibility with your z-uno ?
See you soon

Hello,
I have tried to compile the code into arduino interface.
Only to thinks don't run correctly:
One library: "TimerOne"
One Function: attachInterrupt()
Have you the possibility to add it to the next C++ compiler?
Thanks a lot
Greg

[PoltoS]

attachInterrupt is not yet implemented. Interrupts are very tricki not to kill Z-Wave radio! Timers (also internally use interrupts) are also not easy... This is subject to 2.0.7 (next after next)

[04greg1980]

Thanks a lot for all your job.
Good luck.
I have just received my z-uno and I will try some test very soon.
See you soon
Greg
