16  Using Arduino / Microcontrollers / Re: timer1 on attiny85 on: December 03, 2013, 12:56:58 pm
The TimerOne/Timer1 library does not work but the Timer1 is on the ATtiny85, you just have to program it through other library(ies) or directly low level.  Google Nick Gammon ATtiny85 timer for some code.
17  Using Arduino / Project Guidance / Re: I am a newbie and confused on animatronics with Arduino- guidance appreciated on: November 27, 2013, 12:29:45 pm
I would state that you would want to try to use something like an Arduino Uno and not an ATtiny85 chip when "getting it going".
18  Using Arduino / Microcontrollers / Re: works with UNO, not Attiny85 on: November 27, 2013, 12:14:42 pm
That error often means you ran out of program space in flash.  Probably the font exclusion freed up enough to have it load clean.
19  Using Arduino / LEDs and Multiplexing / Re: RGB with two pins on ATtiny85 on: November 25, 2013, 12:18:53 pm
I think Adafruit Neopixels or similar would provide greater functionality with only one data pin used.
20  Using Arduino / Audio / Re: PCM audio with a Attiny85? on: November 25, 2013, 11:55:17 am
Where would the audio samples come from?  The ATTiny does not have much flash/eeprom/RAM to hold many samples.  Serial?

If you are looking at generating specific tones for different durations, the 'tiny is good at that.  At learn.adafruit.com, look under the Trinket tutorials.  The Trinket Animal uses various sounds for animals (bird, cat, dog).  The final code has two different functions to generate sound (one uses frequency in Hertz but uses more math).  The Trinket Theramin uses that function.

If you would like to attach an eeprom external, the Trinket Audio Player would play sampled sounds, but only 65 seconds worth and it uses all the pins (SPI).  I2C eeproms use less pins but do not come in large sizes.

You might look at the Adafruit FLORA also.
22  Using Arduino / Programming Questions / Re: Attiny85 Serial sketch error on: November 20, 2013, 12:42:48 pm
Or just try softwareserial library - it works great on the ATtiny85
23  Products / Arduino Yún / Re: Yun or Adafruit Neopixel LED library bug?? on: November 06, 2013, 09:17:26 pm
You might post on the Adafruit neopixel forum
24  Products / Arduino Esplora / Re: Using the Tinkerkit input and output points on: November 05, 2013, 06:54:34 pm
Yes, I have a blog post on using the inputs and another for the outputs.

I would look at Adafruit Neopixels.  You can connect as many as you want given Esplora's memory and you must supply enough power via an external source.  You could use one or both digital pins on the Tinkerkit outputs or digital pins on the "Display Header".  See http://learn.adafruit.com/adafruit-neopixel-uberguide and http://21stdigitalhome.blogspot.com/ (search for Esplora for documenting the pins you might use).
26  Products / Arduino Due / Re: Problem using multiple serial ports on due on: October 15, 2013, 11:41:47 am
Break it down into two problems.  Put a nano on the desk with serial and see what data it passes to your console.  Once that is correct, reconnect serial to the Due to see if the Due gets the same values you got with the nano alone.
27  Products / Arduino Due / Re: compile error: RTC_DS3234 library on Due on: October 14, 2013, 10:25:20 am
The _BV code is in the library and is coding low level on the AVR ("classic") Arduinos.   You should see if anyone has made a SAM/Due compatible library.  If not, you'll need to read up on AVR code and equivalent SAM code (yuck).

If you just need a RTC module, the Adafruit DS1307 breakout has a library that will work with AVR and Due.
28  Products / Arduino Esplora / Re: esplora and original lcd problem on: October 14, 2013, 10:16:54 am
Does your Esplora work with non-display demo sketches?  Try to run it through it's paces to see if it is Esplora itself and not the combo.  If the display works 100% on your Robot, that should eliminate the display being bad.
29  Products / Arduino Esplora / Re: Esplora not showing up in device manager; recommendation on solution? on: October 14, 2013, 10:14:40 am
Which display board did you try?  If it was one not 100% compatible, it could have confused or even harmed the Esplora.

Best to post in one of the general support forums, the staff do not respond here.
