One of the limitations of the small 8 bit microcontrollers like ... e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a ...

These days, you could be forgiven for thinking driving an LCD from a microcontroller is ... Instead, [Ivan] decided to drive it directly from an Arduino Uno. This is easier said than done.

The only problem is that the pinout is too small ... the LCD’s input voltage is 3.3V, and these added parts make it possible to drive the device using 5V hardware like the Arduino Uno pictured ...

A typical Arduino microcontroller board is pretty small, about the size of a credit ... essentially divides the capabilities of an Arduino Uno into two boards, with one acting as the ...

It is a set of helper mathods to manage the LCD Alphanumeric display through the AlphaLCD library. This sketch should be intended as a modificable skeleton, where you should add your program; the ...
