The rotary encoder works by using an encoder disk that has 90 slots cut out around the edge of the disk. These slots block and unblock IR light from passing through the disk when it is rotated. 2 IR ...

I will not go into greater detail of the code behind the rotary encoder + arduino experiment, as featured articles and great tutorials are available all over the web. Lab Note: RT & Arduino experiment ...

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: "I looked at all the available rotary encoder sketches ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A measuring wheel is a construction measuring tool. The wheel rotates and, using basic rotational kinematics (s=rθ), you can determine the distance between two points. The video below shows a reduced ...

The device is powered by an Arduino Nano and uses a 1602 serial LCD and KY040 rotary encoder to provide the user interface.

The device consists of 3 3D printed pieces, 8 electronic components and 9 nuts/blots. 3D printed parts: Emitter block Encoder disk Detector block Components: 4x IR LEDs 2x 220 ohm resistors 2x 3M ohm ...
