This tutorial shows a way to control the backlight and contrast level in a 16×2 LCD via software with an Arduino, controlling the backlight ... you can add lcd backlight/contrast level control codes ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

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 ...

Instead, [Ivan] decided to drive it directly from an Arduino Uno ... RAM and flash. The code is available on Github. If you need inspiration for your own controllerless LCD driver.

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these ... Give our PCB fab tutorial a try.

The next stage was to create the Arduino code which I created by modifying code already available from the website to record mph rather than m/s and added extra code to support the 16×2 LCD display.

It will also provide experience with advanced usage of the 16x2 LCD screen and its scrolling capabilities. Finally, it incorporates using the joystick with the Arduino. The presentation material and ...
