Im knew to eletronics and arduino programing, and I have a complex first project:
My idea is to control the brightness of about 26 ,1Watt Led's with arduino using mosfets. The LED's will react to sound feed coming from MAX MSP.
I have a couple of questions:
.What is the best way of powering up the LED's (these have a working voltage of 3.2 to 3.4 volts and a forward current of 700mah).What power suply should i buy and whats the best way to conect them;
. Also there is a limit of how much mosfets can be powered by an arduino, firstly due to its limited PWM ports, but also due to power. How can i solve this since i have 26 leds to control individuali (when the brightness of one LED is at max the following LED in the row lights up, reacting to the Max Msp sound amplitude feed);
Thank you,
DiogoM.
