It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. This Arduino NANO Pinout diagram reference is a handy guide for using this board: Arduino NANO Pinout Description The Arduino NANO pins, similar to the UNO, is divided into digital pins, analog pins and power pins. More interesting Leonardo is jam-packed with features that help users in building amazing projects.Īrduino board consist of the Atmega32u4 which comes with a built-in bootloader, making it convenient to flash the Arduino board with any code. The 8-bit board with 54 digital pins, 16 analog inputs, and 4 serial ports. The Arduino NANO is a smaller, breadboard-friendlier version of the Arduino UNO. The LCDs have a parallel interface, meaning that the microcontroller has to manipulate several interface. ![]() There are many of them out there, and you can usually tell them by the 16-pin interface. Its mean that your Arduino board can directly be used as a keyboard and mouse for your computer. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. The Arduino Leonardo can communicate with your PC diectly via USB. Actually, LCD I2C is composed of a normal LCD, an I2C module and a potentiometer. Therefore, LCD I2C has been created to simplify the wiring. So, there is a no need for a second processor. However, wiring between Arduino and the normal LCD is complicated. Leonardo board arduino is a unique product that differs from all the preceding ones and comes with a built-in USB communication. ![]() It is an ATmega32U4 microcontroller board. A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega8 microcontroller. Arduino Leonardo board Pinout: Arduino Leonardo board Released in the year 2012 on July 23. Before wiring the LCD screen to your Arduino board we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen, as you can see in the image further up.
