AZDelivery KY-040 Rotary Encoder Module compatible with Arduino including E-Book!

AZ-Delivery has extensive instructions on how to wire up and program the KY-040 rotary encoder with Arduino and Raspberry computers. There's also a very helpful e-guide to getting started, which includes a useful Python script that needs adapting to match the GPIO pins on whatever Pi you're using. The e-guide can be downloaded from the AZ-Delivery site.

Husband is happy with it

Nice compact units - work well and are good value for the price.

Very cheap and nasty, about what I would expect.

Good encoder, quick to connect and easy to write code for.

Great product

Produces 2 pulses for every 'notch' - it is supposed to be 20 pulses per rotation but it produces 20x2 = 40 pulses. So if you want to increment by 1 you cannot.

First off, AZDelivery are fantastic, free ebooks on each product to get you started and an email with details, saving on printed material.Rotary encoder, plug in wire up and works a treat, bought these for a project I am doing on a Pico Pi. Been looking for something at a reasonable price, and with the supplied details it makes it very easy to understand how to wire up get it working. Rotary encoders are good for step control of functions within a code or for stepper motors where you require a smooth step transition for say menu selection.Each item is individually packed, with pre soldered pins which are suitable for a breadboard application or to plug a wiring harness into for those projects.
