One of the first things anyone does when they start working with the Arduino is to connect it to a potentiometer and control the brightness of and LED or move a servo. Well, a rotary encoder may look like a potentiometer, but other than also having a knob, it is basically the complete opposite. A

We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated

I am not sure, but it was in year 1999, a non-stop (360 degree rotation) potentiometer found in a stereo music system confused me a lot. At that time, I failed to keyed out the strange potentiometer manufactured by ALPS. Later, I learned that it’s a Rotary Encoder (thanks to internet), and bought one such

An old rotary phone can be used for a number of purposes in your Arduino projects – use it as a novel input device, or use the Arduino to interface a rotary phone to your computer. This is a very basic guide describing how to interface the dial to an Arduino, and get the number
