Arduino Menu Tutorial with a Rotary Encoder and a Nokia 5110 LCD display

In our last tutorial, we examined how to create a menu for your Arduino project on a Nokia 5110 LCD, with push buttons to navigate through it. In today’s tutorial will build a modified version of it as we will use a rotary encoder (in place of the push buttons) for menu navigation. A...

Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial

Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an Electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. By turning the shaft to...

Control accurate incremental voltage steps with a rotary encoder

by Anthony Smith @ edn.com: Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a...
