What is Rotary Encoder and How to Use It with Arduino

A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of menu and Increasing/decreasing the value of a ...

Codename RGB

Remotely control your RGB LED strip from your pc. Story You want to control your LED strip remotely. To do so you need an Arduino with internet capabilities. In this project we will use a Arduino MKR1000. To do so we will need to follow this steps: Build the voltage booster (not necessary if your Arduino can output as much power as your strip needs, usually 12v, but the MKR1000 outputs only 3.3v). Configure ...

Interfacing Stepper Motor to Arduino

In this article, we are publishing a project which explains different aspects of interfacing a Stepper Motor with Arduino. Stepper motor is a specially designed DC motor which comes with advantages of both a servo motor and a normal dc motor. Compared to a normal Dc motor, the maximum rpm a stepper motor can produce is very low. But they have the advantage that they can be positioned accurately. Unlike serv ...

DC Motor Speed Control Using Arduino & PWM

Speed control of DC motor with PC Interface is an easy DIY project. In this project DC motor’s speed is controlled by sending the command through PC. Arduino is directly connected to PC through the USB cable and command is given to Arduino on serial monitor of the Arduino IDE. Motor is connected to a transistor, and the base of transistor is connected to PWM pin of Arduino and motors speed is varied accordi ...

DIY: Measuring Wheel/Surveyor’s Wheel Using Arduino & Rotary Encoder

DIY: Measuring Wheel/Surveyor’s Wheel Using Arduino & Rotary Encoder A surveyor’s wheel may also be known by other names like: clickwheel, hodometer, waywiser, trundle wheel, measuring wheel or a perambulator. All these devices serve a single purpose, which is, measuring distance. The origin of surveyor’s Wheel is from an odometer. Odometer simply counts the number of rotations of the wheel. The distanc ...

Fluke/Philips PM66xx Frequency Counter OCXO Upgrade

In this post I will document an OCXO upgrade board I designed for the Fluke/Philips PM66xx line of frequency counters. Introduction A few months ago I purchased a Philips PM6674 frequency counter on eBay. It's an older 9 digit counter with two channels that has a maximum input frequency of 550MHz. The design feels dated compared to more modern counters, such as my Agilent 53131A. However, it is still a full ...
