led stop blinking after disconnecting the programming cable

Hii!!

  I'am using Atmels ATtiny2313 microcontroller. Few days ago I was able to blink led after disconnecting the proframming cable. but now after disconnecting the programming the led stops blinking!!!!!!why???

Anyone Please help me why this happen????

Plzz help me!

can i still add a laser, speaker, led?

in my robot SC-QR-1 i have allready used all 8 servo-ports.

but can i still ad a laser(to see where it looks), a speaker(for it to call hor help or showing some sound-emotions..   etc.) and some leds(like a red to show power, white/bright to help my "primary-back-mounted-not-night-vision-spy-camera") 

and if yes would the servos disturb the lasers, speaker and leds?

and i was also thinking, stuff like the sharp ir sensors have ir leds in them, could i attach an led or laser to those pins??

 

please reply!! :D

I can't manage to run my arduino on Vista.

I Just got my arduino form the mail, plugged it in my computer followd the instruction given on Aruino.cc, i'm saldy "a Pc living with vista" to quote the apple Ad, and I cannot install driver manually, I plugged my arduino in my pc, a "new hardware found"popped, it searched the drivers automatically, "succesfully" installed them, then, nothing. I can't do anything.

Btw, yes the arduino program is installed.

Also, I have Ubuntu in dual boot but I'm pretty much new to it.

No response from SRF05!

Hello, I am trying to connect a SRF05 to my 28x1 PICAXE starterkit.

 Using the "start here" guide and the How to connect SRF05 to Picaxe 28 pin Project board
I am able to make the SRF05 LED flash like the guide says it should, however I am not able to receive any input in debug.

I have connected every wire like in the picture and I am only using the program provided.

Using Arduino and L298N to control Tamiya Twin Motor Gearbox

I've connected the L298N to one of the motors of the Tamiya Twin Gearbox as per the circuit diagram in the L298N data sheet. But when I set pin 10 and pin 12 to go forward or reverse, nothing happens. The voltage at pin 13 and pin 14 seems to be equal to each other regardless of what I set for pin 10 and pin 12 (with the enable pin on high). This is the Arduino code I have. The diodes I am using are IN4007. I've also tried it with the other H-Bridge and I get the same result.

Quick question

Hello, I'm a noobie at this. Is there a beginners forum? All the best

Robust Autonomous Robot Localization Using Interval Analysis

hi


i'm gonna do my project on autonomous robot.... and i got a ieee abstract.....

here goes....

Abstract :

FIRST Robotics competition

I hope this is the right catergory for this post.

 

So basically our school started a new team this year and we entered into the NY FRC challange which begins january 9th. Now i personally dont know too much about the competition regarding the specs of the parts and build requirements but we can worry about that later. I was just wondering if anyone here has done this at there school or knows more about it and would be able to give a first year team some pointers.

Futaba Controller Servo issues Picaxe

I am trying to use my Futaba Radio Controller, intercept the pulse and then pass it through a servo.
I guess that I could use a relay but I would like to process the signal.

Here is a basic bit of code:

do
   pulsin 1,1,b0
   debug b0
   pulsout 2, b0
   pause 20
loop

this would seem to me that it would basicaly pass the signal from ch1 to ch2 but the servo is rather jumpy(servo moves back and forth).

I read similar post but resistors did not seem to help. it might be the controler.
