1  Using Arduino / Audio / Re: Arduino library for WTV020-SD-16P audio module on: July 23, 2014, 04:22:46 pm
I guess I am confused about the reset which is defined in the sketch as pin 2 but in the schematic it is A3. And A3 in the sketch is defined in the sketch as the clock pin not the reset. Not clear to me at all.

I am trying to get this working and I have a question re: schematic and sketch.  In the schematic it is showing only three pins on the arduino used. Pin 1 of the WTV020-SD-16P going to A3 on the Arduino, Pin 7 of the WTV020-SD-16P going to pin A4 of the Arduino, and Pin 10 of the WTV020-SD-16P going to pin 5 of the Arduino.



But in the sketch there are four pins defined. I wired it up as in the schematic but nothing is working.... What am I missing?

Code:
int resetPin = 2;  // The pin number of the reset pin.
int clockPin = 3;  // The pin number of the clock pin.
int dataPin = 4;  // The pin number of the data pin.
int busyPin = 5;  // The pin number of the busy pin.

Thanks

Thanks I'll give that a shot.

What about the schematic? Does the module only need the three connections to the Arduino and the rest of the schematic  can be eliminated? Or do you need additional pins  on the Arduino. Thanks

Can this module be controlled totally by the arduino? If so what can be eliminated from the circuit? The project that I have in mind for it will require that it operate and change recordings via the arduino. Thanks!

Bump.... any help on this?

I just bought 10 for $5 on eBay over the weekend.  They have the female clamp for LED strips at one end and the 4 pin plug suitable for the typical LED power supply at the other end.  I plan to lop of the pin end

Also, aliexpress.com is the low-volume outlet for alibaba.com.  You will find 10, 20, 50 quantities more easily on the former than the latter.

Can you point me to an example? The ones I have seen are just a bit too narrow with the pin placement too tight together.

I have looked there and I have been looking around other places too, but I am not really sure what the correct connector works best. I am crappy at soldering so a snap on would be ideal for me. When measuring a LPD8806 strip it looks like it would take at least something advertised as a 14mm connector but all I have been able to find are 12 mm like these. http://goo.gl/H462g I would like to hear from someone that has actually had firsthand experience with the LPD8806 and connectors that work and where they got them. I have never dealt with Alibaba and was a little skeptical about the payment system. Thanks.

Is there a snap on connectors for LPD8806 LED strips that is available. Thanks.

10  Using Arduino / Programming Questions / Constants question on: December 11, 2012, 07:01:16 pm
Is it possible to define each color with its RGB equivalent as a constant. I have tried something like the code below but it returns 0 instead of 127,0,0 as I would like. I would like to do this to make my code more readable. Any guidance? Thanks

const char red= '127,0,0';         //Red

setSpoke(0,strip.Color(red));   //red
Serial.println(red);

Thanks,

I have seen that post before and the guy custom programs a chip not an Arduino in assembler and not c. Where I need some help is working with the arrays as I have never used them before and I want to learn using this project.

Hi,

New to the forum and arduino. I have a QuadCopter that I want to modify with a round matrix of LPD8806 RGB LED strips. I have a sample now that I am playing around with to see if my concept will even work. I am also new to C programing so I need a little advice. I want to arranged the LEDs in a radial pattern around the base of the quad, see attached pic. They will be wired in a serpentine manner with the data connections going totally through the entire array and with new power connections every meter of the LED strip. A small example of the array is below. With 0 being the first spoke in the array and 11,12 and 23 being the start of the next 3 spokes.

0   1   2   3   4   5
11   10   9   8   7   6
12   13   14   15   16   17
23   22   21   20   19   18

I want to be able to address each individual spoke and be able to send the entire spoke one color. In addition I would also like to address each, what I will call a ring in the same manner. The first ring being 0,11,12,23 and the second being 1,10,13,22

That being said and since the addresses of the strip can't easily (not sure about this) produced with a regular for loop, I am at a loss as to how to start to program for this array. Can anyone point in the correct direction.... Thanks in advice that you can give this poor lost soul.

Thanks Rob. Will update here at least I have a direction to work towards.

14  Using Arduino / LEDs and Multiplexing / Re: How do i light many LEDs and control them individually on: November 15, 2012, 12:36:52 pm
You might want to look at addressable RGB LEDs found here http://www.adafruit.com/products/306
 or if you search on LPD8806 you will find the same LEDs from different suppliers. There is also a library for programing them found here https://github.com/adafruit/LPD8806  With this setup the data wires are connected to the Arduino and the power is connected to a separate battery of the correct size. You can't power the LEDs from the Arduino as it draws too much amperage and it will cook your Arduino. This is another library that will drive the LEDs from the SPI bus. https://github.com/cjbaar/LPD8806. Good luck.

I think you said that this channel is controlled by a switch on the transmitter, how many positions on this switch? That will determine how many different "programs" you can run.

Right now the switch I want to use is a variable pot. But with the flight mode switch that I currently have, it was originally a variable pot but I modified the transmitter to have a 6 position switch with four trim pots to dial in the exact PMW with the high end of the switch being the high end of the PMW and the low end being the other end of the scale. So this might be a possible solution. Thanks for the feedback.
