#15795 Netduino - WiFi

Posted by monewwq1 on 22 July 2011 - 07:14 PM in Project Showcase

Yes, no problem. I will post the code in a few hours this weekend. I'll provide some details on how to connect it as well.



#15767 Netduino - WiFi

Posted by monewwq1 on 22 July 2011 - 12:49 AM in Project Showcase

I bought a Netduino Plus but decided I really need to go wireless, so I picked up a Gainspan WiFi breakout board from Sparkfun (http://www.sparkfun.com/products/10505) and after some fiddling with the AT commands, I was able to get a WiFi connection going.



#15559 RGB LED color control via web page with Netduino Plus

Posted by monewwq1 on 16 July 2011 - 10:27 PM in Project Showcase

Hi all, I've been playing around with controlling RGB LEDs with my new Netduino Plus. I set up a server on the Netduino that listens for requests on Port 80. Then I built a web page with a color picker control that sends commands to the Netduino. The web page runs on a separate web server on my laptop. The Netduino parses the commands into individual R,G, and B values for the LED. I am using a common anode RGB LED from Radio Shack, connected to three PWM inputs on the Netduino. Here's a demo: I am trying to get a better algorithm for the color generation. Right now I am using SetDutyCycle, but I think the SetPulse method would provide even better color generation. If anyone wants to look at the C# project and maybe help me with the color generation code, just let me know and I will post it.



#15308 PWM inputs and RGB LEDs

Posted by monewwq1 on 11 July 2011 - 12:34 AM in Netduino 2 (and Netduino 1)

I am trying to determine how to get accurate color representation of RGB values with a Netduino's PWM inputs. Specifically, I had worked with an Arduino and the range of the PWM inputs was 0 to 255. On the Netduino, the range is 0 to 100. I want to be able to generate colors based on a scale of 0 to 255 for red, green, and blue. I was able to do this easily with the Arduino. You can see my video of RGB LED color generation with an Arduino. I am unsure how to do this with Netduino. I know that there is a SetPulse and SetDutyCycle function, but I can't seem to figure out how to get a range of 0 to 255 so that I can represent monitor RGB LED values. Any help is greatly appreciated.
