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 ...

This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

This project measures the input voltage using an Arduino Uno and displays it on a 16x2 I2C LCD screen. It uses a simple voltage divider circuit to safely read voltages up to 12V. The Arduino reads an ...

There are cheap LCDs available from China, and when plugged into an Arduino, these displays serve as useful interfaces or even shinier baubles for your latest project. [Michael] picked up a few of ...
