Dimming 230v ac

Hi,

Im trying to dim 230v AC lights with the arduino, so fare i have googled at i cant use a velleman K8064 dimmer kit http://www.apogeekits.com/light_dimmer.htm

It uses 0-10v DC to dim litght from 0 - 98%

the question is how to make the 0-5v pwm arduino output. To 0-10v DC i did finde a site with som info on http://www.nano-reef.com/forums/index.php?showtopic=230743

Can i use this?

Thank you for your reply.

I did find the datasheet i was in the bottom of the page.

I fund out that you can set the volted from 0-12v. so im going to set it at 0-5v i did reed some plase that you neede to make a low pass filter to make the arduino pwm to analog.

Analog in is the 0-12v input.

Datasheet http://www.apogeekits.com/PDF_Files/Light_Dimmer_Manual.pdf

I did find som info in the old forum http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1266079091

that you neede to make a low pass filter to make the arduino pwm to analog.

There is a "build in" low pass filter already in the dimmer kit. So, the good news you don't have to do anything, just connect arduino (don't worry to much about polarity, there is also protection "build in", just try one or another way). The only things I can suggest, if adjustment with kit's RV1 and RV2 would not be sufficient to cover 0-98% range, change resistor R16 (4.7 k) to smaller value 1.0 k.

Thank you :smiley:

im gonna buy it to day end try it out:)
