Description Reads the value from the specified analog pin. the Arduino board contains a 6 channel (8 channels on the mini and nano, 16 on the mega), 10-bit analog to digital converter. this means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. this yields a resolution between readings of: 5 V/1024 units or ,. 0049 Volts (4.9 mV) per unit. the

The Linux USB input subsystem is a single, harmonized way to manage all input devices. this is a relatively new approach for Linux, with the system being partly inconfigurated in kernel version 2.4 and fully integrated in the 2.5 development series.
