Guide to the Arduino Mini

To get started with the Arduino Mini, follow the directions for the regular Arduino on your operating system (Windows, Mac OS X, Linux), with the following modifications:

  • Connecting the Arduino Mini is a bit more complicated than a regular Arduino board (see below for instructions and photos).

  • You need to select Arduino Mini from the Tools | Board menu of the Arduino environment.

  • To upload a new sketch to the Arduino Mini, you need to press the reset button on the board immediately before pressing the upload button in the Arduino environment.

Information about the Arduino Mini

The microcontroller (an ATmega168) on the Arduino Mini is a physically smaller version of the chip on the USB Arduino boards, with the following small difference:

  • There are two extra analog inputs on the Mini (8 total). Four of these, however, are not connected to the legs that come on the Arduino Mini, requiring you to solder wires to their holes to use them. Two of these unconnected pins are also used by the Wire library (I2C), meaning that its use will require soldering as well.

Also, the Arduino Mini is more fragile and easy to break than a regular Arduino board.

  • Don't connect more than 9 volts to the +9V pin or reverse the power and ground pins of your power supply, or you might kill the ATmega168 on the Arduino Mini.

  • You can't remove the ATmega168, so if you kill it, you need a new Mini.

Guía de Arduino Mini

Para empezar a utilizar Arduino Mini, sigue las indicaciones para el Arduino convencional de tu sistema operativo (Windows, Mac OS X, Linux), con las siguientes modificaciones:

  • La conexión de Arduino Mini es un poco más complicada que la de una placa Arduino convencional (ver más abajo para obtener instrucciones y fotos).

  • Tienes que seleccionar Arduino Mini desde el menu Tools | Board del entorno de desarrollo de Arduino.

  • Para cargar un nuevo "scketch" en la Arduino Mini, necesitas pulsar el botón de reset en la placa inmediatamente antes de pulsar el botón de "upload" en el entorno Arduino.

Información sobre Arduino Mini

El microcontrolador (un ATmega168) en el Arduino Mini es una versión físicamente más pequeña del chip en los placas Arduino USB, con la siguiente pequeña diferencia:

  • Hay dos entradas analógicas adicionales en el Mini (8 en total). Cuatro de ellas sin embargo, no están unidos a las patillas que vienen en el Mini Arduino, lo que exige soldar cables a sus agujeros para usarlos. Dos de estos pines inconexos también son utilizados por la biblioteca Wire (I2C), lo que significa para su uso será necesario soldar también.

Además, Arduino Mini es mas frágil y fácil de romper que una Arduino convencional.

  • No conectes más de 9 voltios al pin +9V ni inviertas la alimentación de tu fuente de alimentación, o podrías estropear el ATmega168 en el Arduino Mini.

  • No puedes cambiar el ATmega168, así que si lo rompes necesitarás un nuevo Arduino Mini.

Changed lines 44-61 from:

To use the Arduino Mini, you need to connect:

  • Power. This can be a regulated +5V power source (e.g. from the +5V pin of the Mini USB Adapter or an Arduino NG) connected to the +5V pin of the Arduino Mini. Or, a +9V power source (e.g. a 9 volt battery) connected to the +9V pin of the Arduino Mini.

  • Ground. One of the ground pins on the Arduino Mini must be connected to ground of the power source.

  • TX/RX. These pins are used both for uploading new sketches to the board and communicating with a computer or other device.

  • Reset. Whenever this pin is connected to ground, the Arduino Mini resets. You can wire it to a pushbutton, or connect it to +5V to prevent the Arduino Mini from resetting (except when it loses power). If you leave the reset pin unconnected, the Arduino Mini will reset randomly.

  • An LED. While not technically necessary, connecting an LED to the Arduino Mini makes it easier to check if it's working. Pin 13 has a 1 KB resistor on it, so you can connect an LED to it directly between it and ground. When using another pin, you will need an external resistor.

You have a few options for connecting the board: the Mini USB Adapter, a regular Arduino board, or your own power supply and USB/Serial adapter.

Connecting the Arduino Mini and Mini USB Adapter

Here is a photo showing the Arduino Mini connected to the Mini USB adapter. Notice that the reset pin is connected directly to +5V (the orange wire), without a pushbutton. Thus, to reset the Arduino Mini, you will need to unplug and reconnect the USB cable to the Mini USB Adapter, or manually move the orange wire connected to the reset pin from +5V to ground and back.

to:

Para usar el Arduino Mini tienes que conectar:

  • Power. Esto puede ser una fuente de alimentación regulada de +5 V (por ejemplo, desde el pin de +5 V del adaptador Mini USB o un Arduino NG) conectado al pin de +5 V de la Arduino Mini. O bien, una fuente de 9V de potencia (por ejemplo, una pila de 9 voltios) conectada a la clavija de 9 V del Arduino Mini.

  • Ground. Uno de los pines de masa en el Arduino Mini debe estar conectado a masa de la fuente de alimentación.

  • TX/RX. These pins are used both for uploading new sketches to the board and communicating with a computer or other device. Estos pines se utilizan tanto para subir nuevos programas a la placa como para comunicarse con un ordenador u otro dispositivo.

  • Reset. Cuando este pin se conecta a masa, se reinicia el Arduino Mini. Puedes cablearlo a un botón, o conectarlo a +5 V para evitar el Arduino Mini se reinicie (excepto cuando se pierde la alimentación). Si dejas el pin Reset desconectado, el Arduino Mini se reiniciará de forma aleatoria.

  • An LED. Aunque técnicamente no es necesario, conectar un LED al Arduino Mini hace más fácil comprobar si está funcionando. El pin 13 tiene una resistencia de 1K incorporada, así que puedes conectar un LED directamente entre él y la masa (Ground). Cuando se utiliza otro pin para conectar el led tendrá una resistencia externa.

Tienes varias opciones para la conexión de la placa: el adaptador Mini USB, un placa Arduino convencional, tu propia fuente de alimentación y también el adaptador de serie a USB.

Conectando Arduino Mini y el Adaptador Mini USB

Aquí hay una foto que muestra el Arduino Mini conectado al adaptador Mini USB. Observa que el pin de reset se conecta directamente a +5 V (cable naranja), sin un pulsador. Por lo tanto, para reiniciar el Arduino Mini, tendrás que desconectar y volver a conectar el cable USB al adaptador Mini USB, o mover manualmente el cable naranja conectado al pin de reset de +5 V a tierra y volverlo a su posición normal.

Connecting the Arduino Mini and a regular Arduino

Here's a photo of the Arduino Mini connected to an Arduino NG. The NG has its ATmega8 removed and is being used for its USB connection, power source, and reset button. Thus, you can reset the Arduino Mini just by pressing the button on the NG.
