Electronic components of the projectArduino Nano
The Arduino Nano is a small, complete, breadboard-compatible board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It only lacks a DC power connector and works with a Mini-B USB cable instead of a standard one.

Display oled sh1106
It is a 128x64 dot monochrome OLED display module with I2C interface. It has several advantages compared to LCD screens, and we can highlight its high brightness, very good contrast, a wider viewing angle, and low consumption. of energy. It is compatible with Arduino Rasberry Pi and PIC microcontrollers among others. It works with logic levels from 3.3V to 5V and has a viewing angle greater than 160 degrees. Screen Size is 1.3 inches. It is powered with a voltage of 3.3V to 5V. It can be used in applications such as smart watches, MP3s, thermometers, instruments, and various projects, etc.
