We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine ...

line called for by the LCD protocol. This means you don’t lose any extra pins. Another way to uses the displays with Arduino is to use a smart controller for TFT screens.

To link a standard 16×2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you ...

For years, there has been a clear distinction between the Arduino ... pins. Then there are the pins that double as communication pins. On the Nano, you can access one UART (pins D0 and D1 as RX ...

Then, an Arduino board might be ... module since they connect to different pins (the Wi-Fi shield to the SPI bus, and the Bluetooth module to the TX and RX pins). Another difference between ...

[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...
