16  Using Arduino / Programming Questions / Re: Uploading to Xively on: May 01, 2014, 06:16:46 am
Checkout how it was done here and here .
The Xively parts of the code can be modified to work with your sketch.

Seems like what you said earlier that the led array is the cause of the LEDs turning off slowly.
If using a resistor in place of the array gives a "perfect square wave", then some changes need to be made in the array circuitry for a quicker shut off.
Have a link to the LED array you are using?

Voltage divider at base of transistor keeps it at 10v.
How would it get to 0V? Try removing R8.

Try connecting the + and - leads from power supply to both ends of the strip.
Add a 220 to 470 ohm resistor on the data line, also placing a 1000uF cap on the + and - of the strip can help with power issues as stated in this article towards the page bottom.

Code?
Schematic?
21  Using Arduino / General Electronics / Re: Good quality cheap multimeter on: March 06, 2014, 09:10:12 am
I use the MS8268 for under $30
If you need inductance and temp. readings then:
MS8269 for under $40

You want it to print mm instead of cm in the console?
If so change the abbreviations in the sketch:
Code:
Serial.println("cm");
to
Code:
Serial.println("mm");
And do as  john21403 says to mathematically  convert cm to mm.

Very cool smiley-cool ... or hot  smiley-evil
My 85s should be here this week, great project to play around with.
The wrist band idea is neat, could be done with a few segments of an RGB strip.

cjdelphi, been back to your desktop lately?
Still hoping you'll post the sketch you used to achieve this.

Thanks that will be great.

cjdelphi,
On each color:
What's the max PWM value that you use for a 120mA limit?
What's the voltage drop across the color segment when 120mA is being drawn?

I tried this and to maintain a 200mA draw limit on the green segment I had to use 72 as a max PWM value.
27  Using Arduino / Project Guidance / Re: internet radio player possible with arduino? on: February 13, 2014, 01:24:38 pm
It does it's job, allowing everything to play nice together.
Also gives the ability to code in button control for station selection, maybe add an RTC and have a radio alarm.
Project + (Arduino + Imagination) = Endless possibilities.

 .sch is a file extension used by  EAGLE for schematics.
30  Using Arduino / Displays / Re: issue with tft lcd example code on: January 28, 2014, 07:24:33 am
That sketch is not for UNO.
Compiles fine for Arduino MEGA or MEGA 2560.
