Arduino? Answered

I want to learn about arduino. All I know about them is that they are open source micro-controllers on  which you can write programs. I want to learn all about them how to program them, how to use the analog and digital pins, whats the difference between different types of arduino etc. Any eBook, website or youtube channel?

Hi, I want to get into microcontrollers and stuff. Doo you think that an Arduino is the best way to get into this stuff. I live in the UK and I've been looking at this. I need something that interfaces via USB or serial ( via a usb to serial adater) and this looks ideal. What do you think about these? Are they any good?BTW: Does anyone know a place (other than ebay to get these in the UK?)-josh

Can you help me I have a problem, this program :/*Blink *The basic Arduino example. Turns on an LED on for one second,then off for one second, and so on... We use pin 13 because,depending on your Arduino board, it has either a built-in LEDor a built-in resistor so that you need only an LED. * */int ledPin = 13; // LED connected to digital pin 13void setup() // run once, when the sketch starts{ pinMode(ledPin, OUTPUT); // sets the digital pin as output}void loop() // run over and over again{ digitalWrite(ledPin, HIGH); // sets the LED on delay(1000); // waits for a second digitalWrite(ledPin, LOW); // sets the LED off delay(1000); // waits for a second}it says that the input pin is 13, ok, but I don't see the output pin, WHERE IS THE OUT PUT PIN???Lets say, I connect the positive(longer ) wire of the LED to pin 13(the input pin), and the negative (shorter) wire to what pin, what output pin???Thanks!

Burn Arduino Bootloader to Arduino, from Arduino

I want to burn the Arduino bootloader to an Arduino from an Arduino. I have an Arduino Duemilanove, and I want to take the chip(ATMega328) off, and use it in a circuit, without having to connect the whole Arduino to the circuit. However, I then have an Arduino with no chip. So, Can I just put a regular ATMega328(I know I can just buy one with the bootloader already on it, but I would rather do itmyself.) into the Arduino, connect it to the computer, and use the Arduino IDE(I'm using 0021- the most up to date one) to burn the bootloader to it? If so, how? If I cant, is there any way to easily do it with only another Arduino with the bootloader on it?

Arduino to arduino via bluetooth?

I want to link three arduino's via bluetooth.  One will listen for the other two.  If it receives signal it will set a pin high.  If it doesn't it will set the pin low. Two of the arduino's will be powered off most of the time.  If they power up I need it to link to the other one. So the two will need to power up, link to the one, and start sending signal. The one is just going to power up a light and maybe later also report to the web. The two are just signal generators to let the one know to turn the light on. If I can't link three, I will buy 4 and just make two pairs. Thanks for any answers.

Silly question.

Arduino Relay?

I'm working on a UPS of sorts for an arduino project of mine. Basically if the pwoer goes out I want the arduino to switch to a 9v battery backup. I was wondering what sort of relay I should use and if a transformer would be needed. Ideally I'd like to use a simple power supply with a transformer built in and then have that feed into the relay, but I'm not sure if the 7-12v from a normal arduino power supply would then be enough to switch the relay (normally closed).

Is Arduino the tool for this?

     Hello, I have a question. I'm currently working on a project where data is transferred via radio at a frequency of 916.5 MHz. I need to receive this data, and then send a new signal containing the data out via Bluetooth. I have programming experience, and know C++ fairly well, but have never used Arduino or other microcontrollers. I have looked around, and could not find an answer anywhere else. Can Arduino do this? If so, could you point me in the direction of the radio receiver that can pick up that frequency and Bluetooth transmitter modules (is this the correct word?) that would work for me, as well as what type of Arduino board you would recommend? Thank you! -S
