DIY Arduino Digital Clock Project with DS3231 and LCD Display Constructing a digital clock with the DS3231 RTC Module and 16x2 LCD shows how to practically use the real time clock.

If you ever wanted to adjust a circuit using a digital version of a potentiometer (variable resistor) controlled by an Arduino then this is the easy way to do it - and at a price that won't break the ...

In this tutorial we will learn how to interface a Nokia 5110 Graphical LCD with Arduino and get it working.

The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

Normally driving an LCD requires seven connections to pins on the display, but by using a shift register, [Phillip Warner] at Arduino Playground was able to drive an LCD using only 3 wires. The met… ...

This paper presents a new design scheme that an electronic protractor includes two swing arms and one variable resistor located on the top of swing arms for measuring angles. The variable resistor ...
