 1 Using Arduino / Project Guidance / Re: Help!! I need more decimal places in float. on: April 05, 2013, 02:46:31 pm @HazardMind, thanks alot for that answer.Guys, you would not believe what i found.when you use the calculator in Windows, and divide 22 by 722/7=3.1428571428571428When you use python and do the same, 22.0/7.0=3.142857142857143When you do 22.0/7.0 on an Arduino mega:22.0/7.0=3.142857074737548On a Due,22.0/7.0=3.142857074737549On a Stellaris Launchpad,22.0/7.0=3.142857074737548Why are these values different than what the calculator and Python3 calculates? why these errors? Why are the Boards giving values so different?Regards
 2 Using Arduino / Project Guidance / Help!! I need more decimal places in float. on: April 05, 2013, 12:55:22 pm Ok,So i have been wondering about this for a long time now.Whenever i want to divide a floating number with another, for example float a=1024.0/3.0or float a=1024.00/3.00a is at most only 2 decimal places. What if i want larger numbers, as in more decimal places in the answer? what do i have to do for that? PS: i have tried it on the Dues as well as Uno, they both behave the same.Regards
 3 Products / Arduino Due / Re: Phase shift PWM signals on: March 26, 2013, 05:32:14 pm I had thought about this a few days ago, in some context that might sound very idiotic, But i think, if we have 2 separate microcontrollers, or arduinos, communicating through serial or through some other interface like I2C,we can have a phase shift between the PWM signals.I havent actually tried doing this, and i just *think* this might work. It might also sound idiotic, but i am kinda new here.Regards
 4 Development / Other Software Development / Re: [MOD] Arduino Enhanced Release 1.0.4 for Windows (installer, drivers, etc) +SRC on: March 23, 2013, 06:14:22 pm @eried,Thanks a lot...! Problem Solved.Uninstalled, Rebooted, reinstalled and it worked like a charm.Regards
 5 Development / Other Software Development / Re: [MOD] Arduino Enhanced Release 1.0.4 for Windows (installer, drivers, etc) +SRC on: March 22, 2013, 11:29:47 am Hey eried,By mistake i installed both the non-java version and Recommended version of your Enhanced Arduino 1.0.4 Package.After a restart, one of the versions lost the Arduino icon, and shows up with "Unknown File" icon instead.I have removed both and installed each one again, but i cant seem to get my Icon Back...What to Do??RegardsThe Icon is like this, and it is the same way in Program Files (x86)/Arduino folder.EDIT: I am on Windows 7 x64. Please Help.
 6 Using Arduino / Project Guidance / Re: Coaxial Heli Control Board Replacement--Help Please!! on: March 02, 2013, 07:37:08 pm @retroleftyI dont know if this would give you an idea, but it is bigger than those Micro Helicopters.Link below shows a heli identical to the one i use.http://www.ebay.in/itm/BIGGEST-RC-HELICOPTER-WITH-GYROSCOPE-Volitation-3-5-CH-Double-Horse-/200891823488?pt=IN_Toys&hash=item2ec615f580&_uhb=1#ht_1022wt_1139I have not worked on many projects that involve moving objects like RC Cars and specially not Helicopters. Though have built a Finger Print Attendance logger, a few screen displays, and am currently also working on Tetris on Arduino. A few LCD based stuff too, but nothing original. Wanna learn here...@mauried, i too was thinking of this. I assume that to find the CG or how and where the weight should be distributed, i would tie a thread on the Main shaft and see how the helicopter is positioned. That would give me a fair idea of where the CG lies i guess. Regards
 7 Using Arduino / Project Guidance / Re: Coaxial Heli Control Board Replacement--Help Please!! on: March 02, 2013, 04:28:40 pm And what if i use two accelerometers? one for Horizontal and one for Vertical? would that do??Regards
 8 Using Arduino / Project Guidance / Coaxial Heli Control Board Replacement--Help Please!! on: March 02, 2013, 06:57:43 am EDIT: Dont know where my mind was while posting this in the wrong forum, Moderators, please Move it to the Correct One!!Hey guys,I have  a Coaxial Helicopter, essentially a cheap one, with 2 Brushed motors on it for the blades and another brushed motor for the Rotor Blade.I brought it to convert it to an Arduino controlled Helicopter. Money was an Issue a few days ago, but scince its my b'day, i can ask for stuff from my Mom and Dad now SO please help me with what i need to do and get...3 Brushed Motors, 3.7V and i dont know what current Rating they have. It would need 2 Brushed ESCs, like the Turingy 20A Brushed ESC.Tell me if i am correct.For Stabalisation, do i need both a Gyro and an Accelerometer? A 3 axis accelrometer like MMA7361, would it work?? Why do i essentially need a Gyro sensor??Also i can control the Heli with either Infre Red or the the NRF24L01 RF Transcievers.Is all this OK? what else should i be needing?Regards
 9 Using Arduino / Project Guidance / Re: Proper Tetris on HD44780 based 20x4 LCD ? Possible? on: February 22, 2013, 11:36:16 am @retroplayer,I was thinking of using a characted lcd because i did not have a Graphics LCD on hand at the time....I am just gonna buy one and go for it anyways....Regards
 10 Using Arduino / Project Guidance / Re: Proper Tetris on HD44780 based 20x4 LCD ? Possible? on: February 20, 2013, 12:57:03 pm @Retroplayer, i am pretty sure KS0108 controllers are not used in Character displays, in the above posts, i was referring to KS0108 based graphical LCDs only. Sorry if it caused confusion....also, What does writing to the CGRAM on the fly mean??Regards
 11 Using Arduino / Project Guidance / Re: Proper Tetris on HD44780 based 20x4 LCD ? Possible? on: February 20, 2013, 10:35:44 am Sorry for replying so late, had my exams to write,But i was thinking, a 20x4 HD44780 display, can be thought of as 2 16x2 HD44780s put together right? so wont here be double the memory available for pre defined characters?Also, is it possible to have control over each and every pixel of a HD44780 based display??Regards
 12 Products / Arduino Due / Re: Xbox360 wired controller + DUE as Host, possible? on: February 08, 2013, 02:46:19 pm Bump...
 13 Using Arduino / Project Guidance / Re: Proper Tetris on HD44780 based 20x4 LCD ? Possible? on: February 07, 2013, 05:12:14 pm Thanks for the replies guys,the Custom Characters possible on the HD44780 display make it a problem to be able to define all the Tetris pieces and their orientations.Would a KS0108 display support full fledged Tetris to be played on an Arduino??Regards
 14 Products / Arduino Due / Re: Arduino Due libraries (official and 3rd party) on: February 05, 2013, 07:12:14 pm the LCDBitmap Library runs flawlessly on the DUELocated athttp://code.google.com/p/arduino-lcd-bitmap/
 15 Products / Arduino Due / Xbox360 wired controller + DUE as Host, possible? on: February 05, 2013, 07:05:59 pm Hey guys,I wanna modify an RC Car using an Arduino, so that it can be controlled using ab XBOX 360 wired controller.The DUE can act as a Host device for Mice and Keyboards, but is it possible to use the DUE as a host for the XBOX 360 controller?? if so, HOW?Regards
