This project is a simple people counting system that uses an ultrasonic sensor, an Arduino board, and an LCD display to count the number of people passing through a specific location. The system is ...

This project demonstrates an Arduino-based LCD button counter using the Arduino UNO R4 WiFi and an I²C LCD display. The sketch counts button presses, debounces the input, toggles an LED, and displays ...

[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 own ...

These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Load ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

10-32 - elektor october 1980 LCD frequency counter Tuning scale with LCD A few years ago, building a digital tuning scale required printed circuit boards riddled with ICs. Modern semi- conductor ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...
