General Discussion / Audio Shield driving a speaker advice.

« on: September 10, 2014, 09:51:31 PM »

Hello,

I plan to create a speaking plush doll, but would like to double check the range of speakers that this shield can drive and get some input. Datasheet  Is the data sheet I have found, it gives 80ma and upto 32 ohm. What kind of sound quality can I expect from a speaker in this range or what kind of volume? Is this all dependent on the speaker I end up choosing? This is my first adventure into playing sound other then using a piezo.

Thanks for any input!

TinyDuino Processors & TinyShields / Servos question.

« on: September 24, 2013, 10:58:03 AM »

Hello,

I have a new project that needs to use two servos to automate a puppets head. I have never used servos before so I have been looking at examples online and using a Arduino R3 to prototype. I know the servos are 3v-6v, but is it safe to power two off the a tinyDuino or should I take the approach of using a different power supply?

This is the servo I am using:
