Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

So, what happens when we send a set of data to the LCD Device? Our resulting sketch will be almost simple. The most inspiring source to make this project comes from a blog post by Chris Parish ...

First off, he’s included level converter chips to managed the 3.3V/5V issues. Second, he uses latch chips to translate eight pins on the Arduino Mega to sixteen pins on the display.

[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 ow… ...
