This is my first Arduino project, so appreciate your patience.
I am trying to build a functional Sunrise clock with a significant amount of light (about 200W of incandescent light or equivalent) the plan is to have the Arduino Uno set an alarm to a time when it will gradually increase a light level over ~30min and possibly also sound a buzzer when the light is at full intensity.
nice to have: support both 110V/60Hz and 220V/50Hz as I know I plan to move out of the U.S. in about a year.
I am trying to decide between driving standard AC lights and using high power LEDs
[u]AC light options:[/u] 1. Velleman K8064 dimmer kit costs about $40 including shipping and requires complicated assembly and soldering, supports both 110/220V Link to Amazon: http://www.amazon.com/VELLEMAN-K8064-CONTROLLED-DIMMER-KIT/dp/B008NR8608 power capacity seems OK.
2. Power switch Tails use one ZeroCross tail and one PowerSSR at total cost of $50 with shipping cons: no 220V support, size pro: easy and very safe - all AC power is contained in a closed product. http://www.powerswitchtail.com/Pages/ZeroCrossTail.aspx
[u]LED Light option[/u] 3. use a few high power LEDs with an external DC power supply, I think I will have to drive about 10 x 3W LEDs to reach the 200W incandescent light level pros: easy to find a similar 220V DC power supply when I move cons: need to build a heatsink for the LEDs vs. using a retail level AC light fixture
I am looking for the easier solution, I rather shell the extra bucks and not try to design an equivalent of the K8064 on a breadboard. my electrical skills are limited to a few courses in electrical circuits that I took in my bachelor degree a while back - I have been practicing software since...
appreciate any comments, did I get my options right ? did I miss any easier option short of buying a full product ? (I still want to make this a DIY project, only limit the scope)
