I know it would be really obvious if it was voltage measured but it's constant serial data, I'm just unsure that why when I observe my data, there is a significant period of time where the signal is...

Hi I have confirmed I am getting the right data from my oscilloscope(a query I had in a previous question), I just never realised until I wrote down the 1's and zeros and though about it, the...

I have a gps module, its data sheet is:
http://datasheet.octopart.com/28146-Parallax-datasheet-13529329.pdf



I would like to enter GPS commands into the arduino's serial monitor(at least i...

thanks. i'll give it a try and get back to you, i wont be able to try it just yet so but i will let you know

@ megafiddle There is surerly a pattern to my wavform in /raw but i went through "singe" 20 times yesterday, and wrote all the 0's amd 1's and no pastern was found

Could you explain your code. and when (if when) it will get the data from the module. My main objective is to request the data.
So somehow i will do something to make my arduino manually extract the...

why when I connect the declared tx pin 3 to the declared rx pin 50 together, serial transition stops? I read somewhere they have to be connected for smart mode on modules with RX and TX sharing the...

code used n raw mode


#define RXPIN 50
#define TXPIN 3
#define GPSBAUD 4800
TinyGPS gps;
SoftwareSerial uart_gps(RXPIN, TXPIN);

what will the c command be then. Serial.read/write? Serial.print would just print on the terminal..
or do I use "BYTE" and char?
and yes my oscilloscope does have a single trigger button, however...

to reiterate my previous thread to make it a little easier on what I want to achieve. I have this GPS module and this is its datasheet.
...

Hi, I am having trouble sending commands to my GPS module using arduino, my module works fine in /raw but when i remove /raw to obtain data manually it doesn't seem to work properly. the problem is...

Hey that does work thanks, however my version probably worked anyway, my program still doesn't work with millis or interrupts, after having a google I found that whilst using the software serial...

Hi
I'm using Software Serial library to constantly receive data, however I want the data to received to be displayed(and update in real time) for a certain length of time. I tried using millis but...

unsigned long currentMillisA= millis();
unsigned long currentMillisB = millis();
unsigned long currentMillisC = millis();


if(x==0 && y==1 && z==1)
{
...

couple of reasons, while has its limitations.
It is bad practice to have the condition to break out of the while loop the same as the condition to enter my second if statement.

And i have...

I have a issue: essentially I want a function(s) to run for a certain time but without a delay and to constantly update for that interval.

First I have 2 if statements, 1 with an idle condition if...

hi, is the following what is intended:

if I enter "9.8.44"
when I multiply by two it prints""error-19.6"
another example:
"-3.8-5"
prints "Error 7.60"

Something like this?
if something is wrong is just displays "0.00..."
is that correct?
on another note, do you know why by default without the 5 for decimal places, it is by default 2 decimal...

Hi, thanks for the advice, I'll give it a go, could you please explain why the function "atof" appears to work fine, I had a look around and the only disadvantage I could find was to do with strange...

if (customKey == 'B')
{
int x;
float y;
lcd.clear();
lcd.print("nmbrs prsd were:");
lcd.setCursor(0,1);
sscanf(lonarray, "%d", &x);
y=(2*x);
lcd.print(y);

Thanks, I knew it was something simple, is there an easier more sound way of turning an array into an integer without using the "atoi" function? I would like it perform some sort of mathematics with...

Hi, I need some urgent help with arrays please, the purpose of the program is to check for a key pressed and store it into an empty array. And then print the entered sequence on the LCD after 'A' is...

Hi
I have a small problem. I am trying to display characters on my 16x2 LCD shield with a 4x4 keypad connected to an arduino uno. When I press the keypad buttons, the corresponding character prints...

Vart, replacing the b with a 4 worked thanks ^^
Just 3). to clear up now, I'm sure the solution will be pretty simple, and involve a similar process to when I used the enter key to confirm rather...

Thanks, i'll give that a try, and the reason for that is, say for example if I want to control the system remotely where the system is in another building a 5 minute drive away. if I enter the wrong...
