I have a tested library that i designed. with examples
about 11 months ago
Just an FYI i bought some digital pots for audio. if your like me and want push button functionality you want a scale to go with this. using the wiper resistance i found dbGainMin to be~ -40db. now I get why digital audio seems to use a 40 digit scale, 1 per -db. the important thing is i cranked out the equation for software audio using db to voltage gain eq., voltage divider.This is assuming optimal settings for a 10K.(at low volumes the steps size of 1 is larger than the accuracy of an 8 bit version, not sure which this is. i get a percent precision around .39%)
hope this helps others. Please check my math. I haven’t made near enough mistakes to be an expert.
I chose to use a count from 0-40 so i included a - in the eq.
Something doesn’t add up. Either it is the comment or the action.
Line 25: “SPI.transfer(0x60); //60= disable Oscillator and Battery SQ wave @1hz, temp compensation, Alarms disabled”
Why are we disabling all these things. Is that permanent.
also is there any using them?
Just got this with the audio jack. Plan to use this just after the RN52 breakout(bluetooth audio) to add an aux port. Any comments as to if this is a bad idea?

can we get an example with the xbee style wifly(RN171)?
ur rx and tx are both 5v on the board im guessing and the wifly needs 3.3 commsignals etc.
I am wanting to control the KIT-09612 with my arduino and do some cool stuff. Would it be possible to use this as the interface?

I am the Director of the Fort Hays State University Makerspace. We are almost done doing a dancing light show with 14 mini Christmas trees, one for each band. I would say the code to run this is a 4 or 5 out of 10 for simplicity. The only complications are the arrays and the digital controlled chip. This is a great backbone for our holiday light show and works great. Now to add an MP3 shield.I would suggest this project for others!

the voltage is stamped on the sheathing as 300V
about 2 years ago
I am unsure of the specifics of this setup. I see 20-30 mA as the current and 5 V as the voltage. Can anybody give me any information as per the voltage and current so that i can properly use it
