Programming
The Arduino Mini can be programmed with the Arduino software ( download). For details, see the
tutorials.
To program the Arduino Mini, you will need a
adapter. See the page on
The ATmega168 on the Arduino Mini comes preburned with a
it without the use of an in-system-programmer. The bootloader communicates using the original STK500
protocol (reference,
You can also bypass the bootloader and program the ATmega168 with ICSP (In-Circuit Serial Programming); see
the page on
for instructions on using a programmer to upload a sketch.
Input and Output
Each of the 14 digital pins on the Mini can be used as an input or output. They operate at 5 volts. Each pin can
provide or receive a maximum of 40 mA and has an internal pull -up resistor (disconnected by default) of 20-50
kOhms. Pins 3, 5, 6,
9, 10, and 11 can provide PWM output; for details see the
USB (or other) adapter is connected to pins 0 and 1, it will interfere with the USB communication, preventing new
code from being uploaded or other communication with the computer.
The Mini has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). Inputs 0 to 3
are broken out onto pins; input 4 to 7 require soldering into the provided holes. By default the analog inputs
measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin
and some low-level code.
