I want to have built for me a simple circuit that allows me to use a netduino plus 2 [url removed, login to view] to drive several chains of LEDS such as http://www.amazon.com/gp/product/B002QQ1YOM/ref=ox_sc_act_title_7?ie=UTF8&smid=A325274ZEF9XYZ with a power supply like http://www.amazon.com/gp/product/B004IKJU7C/ref=ox_sc_act_title_6?ie=UTF8&smid=A325274ZEF9XYZ.
basic details microcontroller has 4 PWM pins each can only work with 25mA one strip of LEDs draws 15.3 watts.
I would like a board as well as the details of its component parts that will allow me to hook up the power supply listed to the board and have the 4 PWM pins able to control 4 "channels" on the board that allows (i would imagine through a transistor) the low current signal from the microcontroller to trigger the high current from the other power supply at a high speed so that I can manage the PWM duty cycle with the microcontroller. Each channel I would like to be able to drive at least 2 of those LED strips with some safety margin to not damage any of the core components.
[url removed, login to view] seems to have a good example of how to do this.
I will pay 100$ for the development of the prototype and the details of the components in addition to covering the cost of the components. I may also ask to have additional (probably no more than 10) made at 50$ each
