This DC Motor controller provides direction and speed control of brushed DC Motor using Rotary Encoder. This is Arduino compatible hardware that consists of LMD18201 DC motor driver chip, Atmega328 microcontroller, Rotary Encoder, L317 regulator, and other components.  Hardware offers...

A rotary encoder is a position sensor that converts the motion of a knob into an output signal that is used to determine the direction the knob is being rotated. Rotary encoders are usually attached to motors and are used to ensure that the motor stator and rotor positions are always...

The project described here is a compact stereo volume and balance control with rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on...

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...

I2C Encoder V2 is a tiny smart board for connecting multiple rotary encoders on the I2C bus and it's live on kickstarter. The I2C Encoder V2 supports various type of rotary encoder with one footprint: Standard mechanical encoder Illuminated RGB encoder Clickable rotary...

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...

SimonM83 has posted a new tutorial on how to implement an Arduino menu using a rotary encoder. The tutorial goes through the hardware setup and sample code is provided. Rotary encoders with centre-push buttons are cool input hardware for projects, especially if you want to be able to...

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...
