Sorry for my bad English. Is there a shield or some easy way to convert the 0-5 V PWM to 0-10v.

Simply use a transistor. Small amplifying transistors will give you what you need.

like so:

From a software standpoint, I am fully absorbing the concept of utilizing the Netduino PWM pins,amplifying the signal and subsequently controlling a low voltage 0-10v DC dimmer (like that on certain BuckPucks) but being more of a software developer than an electrical engineer, I am not following the circuitry.

Can someone list the exact components and diagram how to achieve this on a breadboard with either a transistor,opAMP or other circuit?

Essentially I want to use the Netduino to control dimming on a Luxdrive Buck Puck

Any assistance would be greatly appreciated.

Time ago I wrote this article: http://tinyclr.it/se...-power-led.aspx
It's a very basic way to dim an high-power led, but it should help.


It's in Italian, so please use any translator.

Thanks, that is indeed useful but I am really in need of circuit and specific components necessary to emulate the output of a 0-10v low voltage dimmer. Since the arduino PWM is done at 0-3.3v, I need a sketch on how to convert the netduino's 0-3.3v signalling to 0-10v which will be used to dim the following LED driver LuxDrive A009 BuckBlock

for me the circuit shown above using the "small amplifying transistor" is a start but I am not much of an electrical guru to know which specific pieces make up that circuit.
