Yes that's the one. You'll also need a relay that will suit whatever voltage your controller channels output unless you want to use the USB function (And have it connected within 5m of your PC) of the Arduino.dougd said:

Ordered my Arduino today. How is this project coming along? I cannot wait to put 200 strobes in my display.
I was planning on running 6 strings of 33 strobes or 8 strings of 25. Is this going to be possible with this project? Is the sting going to have to be one continuous string of 200 pixels?

From what Justin has said, he is going to look at multiple strings next. That being said, I can't see how you'd be able to control each of the strings individually from the arduino, unless you go for the USB control method. My guess is that if he gets the multiple strings working, all strings will go on at the same time.. Benefit of this is that if you get a faulty pixel, there's less effect.

Just out of curiosity, why do you want to drive 6 strings of 33 instead of 1 string of 200? Do you want to control them individually or do you just want some sort of redundancy? I've tested 300 strobes in a single string and it works fine, but if there's a need to run multiple strings I can look at adding in multiple strings.dougd said:
My initial mention regarding multiple strings was just in case the strings couldn't handle long strings.

I envisioned the controller in the center and my strobes were going to go out in 6 different directions from the controller. One string of 200 pixels will work. I will just have to get creative in how I lay them out in the yard. No problems at all, cant wait to give this a try. Thanks.

Updated revision to support up to 9 strings and relay inputs. Hope that helps.dougd said:

I've ordered some C9 faceted covers from Ray, so when they arrive I'll report on how they work.
The new versions are marginally too tight to fit over the strobes, so he recommended against those. The old versions are a bit loose, but he thinks can be used with glue, so that is what I've ordered.

For my twins was the excuse I started with.
The new versions are indeed to tight to fit I discovered after ordering 1000 
I am going to try and drill out the hole slightly to see if I can make them fit.

Thanks will give this a go when the covers arrive next week. Hopefully it's not too painful a job!Skunberg said:
Anyone know if the chip is on the input or output side of the pcb on these strobes?

Answering my own question - chip is on the output side of the PCB.Kane said:

After hooking these up, I agree with other comments - they're not too bright, which is a little disappointing. Wondering whether to even use them, but I might wait until the C9 covers arrive and see how they look with those.
