31  Using Arduino / Project Guidance / Re: GPS (S1315RL) interfacing with arduino Mega on: March 29, 2014, 12:34:29 pm
Please help me by posting a link to the GPS unit, a link to its datasheet, and your code so far.
please help
32  Using Arduino / Project Guidance / Re: Does anybody use freerouting.net software for PCB building? on: March 28, 2014, 11:01:42 am
Surely asking on the freerouting.net forum would make more sense?
33  Products / Arduino Due / Re: Programming Arduino Due on: March 28, 2014, 08:54:01 am
Yes, the package type makes no difference.
34  Using Arduino / Microcontrollers / Re: Avrdude intermittent problem (Mega2560) on: March 28, 2014, 05:13:01 am
Strange, that's the command line used by the Arduino IDE
35  Using Arduino / Microcontrollers / Re: Avrdude intermittent problem (Mega2560) on: March 27, 2014, 11:03:19 am
try
avrdude -c wiring -P com12 -p atmega2560 -b115200 -U flash:w:plus1.hex:i
36  Using Arduino / Programming Questions / Re: Clear LCD once in loop on: March 26, 2014, 12:00:46 pm
if(number > 10) {
    //clear lcd once and keep printing the rest of the numbers
    lcd.clear();
  }


try

if(number = 11) {
    //clear lcd once and keep printing the rest of the numbers
    lcd.clear();
  }
37  Using Arduino / Programming Questions / Re: Getting a random led to blink, help needed for a newbie! on: March 26, 2014, 11:14:50 am
You flash the LED so fast in setup that you cannot see it, also it should be random(9,12) to generate a number 9,10 or 11

I think you may have loop() and setup() mixed up
38  Using Arduino / Microcontrollers / Re: PC2102 Driver on: March 26, 2014, 10:33:26 am
Here you go
39  Using Arduino / General Electronics / Re: how to use a relay with 5 pins on: March 26, 2014, 06:51:02 am
It MAY be like this :

COIL +ve                                            Normally Open

                                                            COMMON

COIL -ve                                             Normally Closed
40  Using Arduino / Microcontrollers / Re: arduino nano clone is not working on: March 26, 2014, 06:16:08 am
Please post a full schematic, as well as a gerber/manufacturer image of both sides of your board, and possibly a close up in-focus photo of your boards (again both sides).
41  Using Arduino / Microcontrollers / Re: What do most compaines use for their commerical microcontrollers? on: March 25, 2014, 04:41:32 pm
I've designed and distributed a display controller to an advertising agency, they have over 3000 units with an atmega328 running at 8Mhz TQFP, as well as dozens of other installations based around  the same MCu, and have seen 'commercial' products with laser etched chips that are clearly Atmel or PIC chips.
42  Using Arduino / Installation & Troubleshooting / Re: not in sync-problem on: March 25, 2014, 02:28:57 pm
Start with basics - what type of arduino have you got? Where did you get it? (is it an official one or a clone/copy) what COM port does your computer show, what drivers did you install, do you have anything plugged into your arduino, have you tried another USB lead, USB port & computer?
43  Using Arduino / Programming Questions / Re: Change Frequency arduino mega to 10kHz and 1khz on: March 25, 2014, 02:22:54 pm
Please look at the data sheet for the 2560 chip and you will find the answer why you can't do this.
44  Using Arduino / Programming Questions / Re: What does - digitalWrite(OutPin, correct ? HIGH : LOW); Mean/do ? on: March 25, 2014, 10:43:04 am
Cheers peeps.
and it saved 4 bytes of flash.
45  Using Arduino / Programming Questions / What does - digitalWrite(OutPin, correct ? HIGH : LOW); Mean/do ? on: March 25, 2014, 10:18:54 am
Hi all, I've seen this type of structure used in sketches but don't understand what it actually does!
I'm looking for a command that will write HIGH or LOW if a statement is TRUE/FALSE , Is that what this does?
