Hello Netduino Folks !
I want to control a 12VDC fan speed using my NetDuino board plus. And I don't want use PWM. So I need a D/A convert
to control the speed of fun. I'm a beginner in electric hardware. Could you help me and give me soam advice in term
of D/A shield choice.
Thanks!
help with fan control

Hello Zendy and welcome to the community.
May I ask you why don't you want to use the PWM?
However, there are several ways to drive a fan without PWM, but the circuit is getting more complex.
In this case, the simplest solution coming to my mind, is using a LM317 (adjustable regulator), feeding into it a supply of *at least* 16-18V. Do you have it?
Other very important questions are:
how much current does the fan requires?
what kind of motor is (brushed)?
Cheers
Biggest fault of Netduino? It runs by electricity.
