Well, I think the PCBs are on the way...I got an email today from SeedStudios that said the order is now "traceable," which I suppose means they are en-route.

Yeah, I need something...I realized over the last few weeks, that when my RGBW(WARM)+W(Cool) LED strips come back on after being off at night, they don't stay on the color that was on when the lights went off the night before. And, they come back on at a lower intensity than they were set at the night before as well. So, something like the LED Controller you linked to would be pretty cool, and probably be much more consistent. I'm curious to see what the PAR is of these LED strips, and then I'll do something about a controller, assuming PAR is sufficient. If not, then I have to go back to the drawing board, which may require a completely different driver/controller or series of drivers/controllers.

PWM/ LCD/ RTC all included..
Yes it is more expensive..

I visited the link, and I can see that the Shields expand the various options, making it a nice neat little package.
So, the shield at the following link includes the screen, and plugs directly into the Uno, correct?
So, do you purchase the pinned header to adapt the shields to the Uno separately, or does the Uno already have the male header pins in the pacakage, and all you have to do is purchase the shield itself for whichever of the shield functions you desire?
Do you know if the Nano version acommodates the shields also?
|04-02-2015 12:16 AM|
A shield is any board that fits directly over an arduino usually via male header pins. Something like these https://www.sparkfun.com/categories/240?page=all
So you can mount the lcd and all other components ( not as much as on the cep) on the shield; a small foot print.
A nano should work. It's a 5v logic like the uno.

Yeah, that's true...actually, I hope to have O2Surplus solder one of the PCBs up too, maybe all five of them. He has the parts to complete five of them. So, if I do that, then the CEP will have a smaller footprint, etc...
I have access to a Nano, which means I should end up with two of them in the end, some from the PCB design, and one via a Nano.
What's the difference between the Nano and the Uno. Should I get an Uno if I get a Nano? What limitations are placed on me by only having the Nano...don't want to miss out on any of the potential other projects I might be able to mess with, and I really wouldn't be opposed to also getting an Uno if it has a lot more capability.
Sorry, but what's an Uno "Shield?"

|mistergreen||Well, you can save money and build it from scratch with an Uno. It won't look as nice but it'll be cheaper, maybe build yourself an Uno shield using wires instead of a PCB.|

SeeedStudio doesn't have all of the parts in their inventory to complete the project. So, they declined to quote the PCBs with the parts soldered-up.
If anyone on the forum wants one of my extra PCBs to solder-up themselves, then send me a private message.
|04-01-2015 02:58 AM|
Yes, very good point Mistergreen...In fact, I am in contact via PM with O2Surplus about that very subject. So, I am hoping there's an Uno in my future pretty soon.

|mattinmd||Pro lets you do a few things like have private instructables that are only visible to those you send a link to. Useful for draft/review (later made public) or club materials (not made public), etc.|

|mistergreen||Hey so I got an email from instructable wanting my projects I listed on Youtube on their site and they'd set me up with a free pro account. I had no idea they had a pro account. Why do people want to pay them to post?|

That's the cable. That plugs into your computer and the FTDI part plugs into the header on the CEP board. You can upload your Arduino sketch with this just like a normal Arduino. Make sure the black wire goes to ground.
Or you can pop out the Atmega chip like I mentioned earlier. $20 for a cable is steep while you can buy an Uno.
|03-31-2015 05:21 PM|
Just to clarify,
Do you have a link that depicts the USB/FTDI adapter? You are referring to just the cord that plugs into the board for access to the chip via the Arduino, but different than the pin header for same, correct?
Looks like this?
The part that we want soldered to the board is the receptical for the USB/FTDI cord, FTDI1 1X06 .1" pin header, soldered in the area where the PCB is labeled FTDI1, right?
|03-31-2015 04:52 PM|
Thanks very much O2 and Mistergreen!
I'll send SeeedStudios the links for both the chip and the holder, O2, so they'll know what I'm referring to with respect to the one already with the bootloader, as well as the pin socket, and they can add them to the Bill of Materials to quote some of these to be soldered.
I don't know how much of the bill of materials they'll have in stock, but they have an abundance of parts available in that part of the world, so I assume the parts would be easy to obtain, if they're so inclined. Just depends if they want to do it with parts they don't already have.
With respect to the parts you have 02, I am going to send a couple of the PCBs your way, unsoldered, and we can use up some of your parts. Just as soon as I receive the boards, I'll PM you for a mailing address. That way, we can use up some of the spare parts you have in the process so you aren't stuck with them.
SeedStudios had already apparently finished my PCBs (unsoldered) before they were able to stop the process. I was kind of hoping they would delay the order so that some of my (5) pc. PCB order could be soldered. But, at least this way, if we know what the total cost of the boards will be, soldered, then other forum members can order some if they want to build a PAR meter using the PCBs instead of the Arduino. And, I haven't given up on the Arduino yet either. I am eager to learn...

Here's a link to the chip if you need it-http://www.digikey.com/product-searc...ader=search_go
They're also available for sale on FleaBay. Many with the bootloader already installed. I've got ten of them if you need some. I burned the optiboot bootloader to them myself, so they're ready for use.
