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 ...

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 ...

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his ...

[Usmar A. Padow] put together an Arduino Uno, SD card, four line character LCD, and PS/2 keyboard. but he’s also included alternative options to go without an LCD screen by using a computer ...

Powered by an Arduino ... on a Nextion LCD touchscreen and then the machine takes care of the rest. It rotates the gear by the calculated pitch, then moves the gear into the circular cutting ...

The components required for this project are minimal: an Arduino, a 1.28″ round GC9A01-driven TFT LCD, a handful of jumper wires, and a few buttons. The buttons chosen for this project are two ...

Now joining the Arduino MKR series of boards – aimed at IoT projects – is the MKR IoT Carrier, a new carrier board with a colour display and embedded sensors. Small and circular, it can read ...
