Thanks but we'd like to use analog RGB strip. We have allready ordered them. Reason is that they are cheaper.
Im trying to get some tips and tricks or maybe some code parts how we should get started.
RGB strip as in not individually controllable LEDs, all LEDs in the strip are the same color based on PWM control of the R, G, and B pins, with 12V applied to the common pin?How many groups of 3 LED segments are you planning to power? Each group needs about 20mA/color.A N-channel MOSFET like AOI-510 or AOI-514 per pin may be all you need with a 180 ohm resistor between the Arduino PWM pin (3,5,6,9,10,or 11) and the MOSFET gate, and a 10K resistor from the gate to Gnd to hold the MOSFET off when the Arduino resets. Connect the power supply Gnd to the Arduino Gnd so there is a common reference point.http://www.digikey.com/product-search/en?keywords=aoi514Here's a video of 8 fading some single color strips up & down on a board I offer.http://youtu.be/hAVf1D1L-7c
That dosn't sit very well with your previous statement.They are cheaper because, as CrossRoads said, the whole strip has to be the same colour. This limits the display you can get.
Yes you need two chips if you have two audio channels.I would advise you to just start with one first and get the feel of it.
First off most Instructables are crap and contain errors. My advice is never to try and learn anything from them. We seen to be an Instructables support unit at times and it is very annoying.Yes you need two chips if you have two audio channels.I would advise you to just start with one first and get the feel of it.
I agree, except he goes for the spectrum shield which has 2 MSGEQ7s already.I´m playing with it at the moment: OLED audio visualisationLED audio visualisation
