Hi, does anyone know if you can control the arduino chip from a program on your computer ?

like for example I would like to build a program that tells me the room temperature and have the arduino chip running the temperature sensor and sending the data to the program on my Mac... is this possible using programming skills in both arduino and software ?

if so can someone tell me a couple of tutorials for IOKit in mac os x, as I think this is the way to start smiley-razz

Never tried zTerm, nice idea on applescript thing post a link when you finish it. I have stopped developing USBConnect, however, if someone wants further releases with certain features just post, I basically wrote it for personal use smiley-razz
Lately I been busy developing a kernel for the intel 32 and 64 bit series... When I had to get input I can't say how much I wished I was coding an OS for a PDA or something using arduino rather than Intel, 2 weeks trying to figure out how to get input and make an IRQ table and you will love microcontrollers, Much love to the micros!.

I also been working on a simple program for arduino that whatever data you send it gets saved into bytes 0 - 512  so memory locations 0 - 13  if  0 has the byte 0 it sets the power for that port to LOW if its 1 then it sets it to HIGH, so as long as you power up your arduino ur program runs off the EEPROM.

Hi, today I was bored so I played around with the serial API's in mac os x and came up with this app http://next-tech.net/usbconnect.zip. The GUI is pretty nice, so far it lets you specify the baud rate, the device path, and the information to send (ASCII only so far). I have tested this app to run a couple motors from my mac and manage them all from the computer. smiley-razz

ye I am but still it should work smiley-razz   the LED works with 2 and 3V when i use my double a batteries to power them    Im using a red LED not that this is much help... I had it around so  I don't really know.

Hi, when I connect a LED to any port it works... except on port 13 anyone knows why this is ?

EDIT: I read that it isn't supposed to work, but I just thought I saw it work last week when I tested the chip maybe I just thought wrong.... did I ?   LED blink works fine with the light  built into the board.

lol ye I fixed it smiley-grin  I didn't read that you had to reset before trying to load software
thnx anyways fellow geeks.

I burned one of my LEDs... which goes back to the point of reading before doing smiley-razz
I didn't know I needed a resistor and it was a 3V LED

Hi I just bought one of your boards it won't let me burn the bootloader nor upload software to it tho. The Arduino 05 IDE detect the board and lists the following ports
/dev/tty.usbserial-A3000XMa
/dev/cu.usbserial-A3000XMa
/dev/tty.Bluetooth-PDA-Sync
/dev/cu.Bluetooth-PDA-Sync
/dev/ty.Bluetooth-Moden
/dev/cu.Bluetooth-Moden

I have selected the second one or /dev/cu.usbserial-A3000XMa
I have the speeds at 9600
And I have the ATMega8 selected
And when I click burn bootloader I get the Programmer is not responding  error
I went to bluetooth preferences and disabled it but it still being listed there (since I heard the PDA sync might  be the problem)

Please help me
thanx in advance

Hi, im thinking of making my own board like arduino, I looked at the schematics but the ones on the main page do not include USB, can anyone post a link to adding a USB to the ATMega8 ? I really want to make my own board so I can know how everything works.  If you post a link it doesn't necessarily have to be to arduino, since arduino is so complex I just basically want to learn how to interface the ATMega8 with USB so I can make my own board, the size I want it to be.

Do you have the arduino on a surface such as a cushion ? if so that might be why it reacts to your body's motion else it might be poor wiring.

well it was working and I've tried it on both sides and all to try to make it work again but it doesn't. My other theory for why it messed up was I had it laying on top of the arduino board so I suspect that maybe one of the metals touched a part in arduino with really high voltage.... just a thought tho I really don't know where I messed up it was working I left for a while when I came back 5 minutes later... it was busted and wouldn't light up.

naw neither the characters nor the backlight is lighting up... they were, i had the LCD resting on on top of the arduino while i  went to get more wires when i came back i saw it was off i thought one of the cables had moved so re wired them all up and it still didn't work, B4 I left to get more cables the squares were turning on

Hi, I bought an LCD from sparkfun electronics I got it to work just fine but 2 minutes into this the LCD burned out or something, all I know is it  isn't lighting up anymore when I connect ground and 5V cable. The datsheets are here http://www.sparkfun.com/datasheets/LCD/GDM1602K.pdf   I connected 5V cable to pin 2 and ground to pin 1 in the LCD.

14  Forum 2005-2010 (read only) / Interfacing / interfacing a 3 pin temperature sensor (HELP!!) on: November 22, 2006, 07:06:21 pm
hi I tried wiring up a temperature sensor I found on sparkfun but it doesn't seem to be working.
http://pdfserv.maxim-ic.com/en/ds/DS1820-DS1820S.pdf those are the data sheets I keep seeing that on the drawings ground keeps changing place and so does input :|

Im a newbie to hardware... please help with both wiring and code. My current code goes as follows:
Code:

int inPin = 11;   // choose the input pin
int val = 0;     // variable for reading the pin status

void setup() {
  Serial.begin(9600);

  pinMode(inPin, INPUT);    
}

void loop(){
    
  val = digitalRead(inPin);  // read input value
  if (val) {         // check if the input is HIGH
  Serial.println(val);
  }
}
and my wiring connects the first pin to ground the middle pin to port 11 in arduiino which in my code I specified as input pin and my 3rd pin is connect to the 5 V power supply

Thanks in advance
