Arduino uno or nano : what to choose

A common question which crops up is should I choose an Arduino uno or nano for my projects First of all lets look at the classic Arduino Uno The Arduino Uno The Arduino UNO is the most famous of all of the Arduino boards.The Arduino UNO has 6 analog inputs and 14 digital I/O where 6 of them are PWM outputs. It uses a ATmega328 processor with 32kB flash memory. The clock speed of the Arduino UNO is 16Mhz and its size is 68.6mm x 53.3mm. One of the big positives with the Arduino Uno is that there are masses of shields that…
