 1 Using Arduino / Motors, Mechanics, and Power / 0-15 V DC motor on: February 22, 2011, 07:50:53 pm Is there a good way to get the ArduinoMega2560 to output 0-15 volts?  Our motor needs at least 10 Volts to spin at the speed we need and a smaller motor wont work due to the load we are trying to spin.  We have tried a MOSFET and it keeps blowing the IC.  The only answer we have come up with is to put a 7.5 volt battery in series with the 5 volt output from the arduino board.  Any ideas?

 3 Using Arduino / Programming Questions / Re: simple C question on: February 01, 2011, 05:19:45 pm well basically what I am trying to do is light 2 different pins of the same RGB LED to 2 different intensities.  When I try and make yellow (green + red) there is too much red.  So what I want is green at 100% and red at 75%.  It needs to be done in the same time frame which is why I want a multi variable loop.  I will definately try these suggestions out.  Thanks

 5 Using Arduino / Project Guidance / modbus on: February 01, 2011, 04:04:46 pm has anyone tried to communicate with an arduino using ModBus or TCP/IP?  Are there protocols for this already?
 6 Using Arduino / Programming Questions / simple C question on: February 01, 2011, 04:00:17 pm What I want to do is control a loop with 2 independent variables (x and y for instance).  Something like this.   for (int x=0,int y=0; x<=100 && y<=255; x++, y++){          analogWrite(PWMpin13, x);     analogWrite(PWMpin12, y);     delay(10);     analogWrite(PWMpin13, 0);     analogWrite(PWMpin12, 0);   }I want one write sequence to max out at 100 (x) and a seperate write sequence to max out at 255 (y).  I know there is a way to do this, but everything I try either errors or doesn't work correctly.  It's probably some silly syntax mistake.  I appreciate any help you can offer.
 7 Using Arduino / Interfacing w/ Software on the Computer / Re: download lost program on: January 31, 2011, 12:08:45 am Well that's thoroughly crap! It wasn't too bad. I salvaged a piece of the code from another file but I still have to rewrite the rest. I appreciate the help and the quick response. Thanks guys.
