Here's a diagram of the pin layout of the Arduino Mini: You can't remove the ATmega168, so if you kill it, you need a new Mini.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.
Two of these unconnected pins are also used by the Wire library ( I2C), meaning that its use will require soldering as well.Īlso, the Arduino Mini is more fragile and easy to break than a regular Arduino board. 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. There are two extra analog inputs on the Mini (8 total).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: 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.You need to select Arduino Mini from the Tools | Board menu of the Arduino environment.Connecting the Arduino Mini is a bit more complicated than a regular Arduino board ( see below for instructions and photos).

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:
