Incremental Optical Rotary Encoder for Arduino 360P/R Wide Voltage Power Supply DC 5-24V 6mm Shaft Quadrature

Using this an encoder for older games that support this type of controls. Seems to work fine when used in conjunction with an "Pro Micro" board.

Yellow = A phase, Blue = B phase, Red =Vcc power +, Black = V0There is no yellow wire should change the connection description.

This is a very nice rotary encoder. I purchased this, along with a beautiful machined aluminum knob, for a hobby project. For quick breadboard projects it is not as convenient as a cheap rotary encoder you can plug into a breadboard, but the feel of this encoder makes it well worth the slight inconvenience. I have used it for Arduino and FPGA projects and will always use this rotary encoder over the cheap ones.If I could suggest one improvement it would be to add pin headers to the power and IO pins. It was easy enough to add these myself. Attaching pin headers makes it easy to use with a breadboard or Arduino header.

Using the code in other reviews, made a tool to measure smooth concrete beams 150ft long. Very repeatable, very pleased. Purchased with rubber wheel and encoder bracket and both fit well.

This thing has no business being this good at this price. Smooth operation - 1440 pules per rev in standard quadrature configuration (2 phase). M3-.5 screws fit the mounting flange. I'm feeding this thing 5 volts straight from USB, two encoders and a Teensy board drawing just .3 watts - whats to complain about.

The media could not be loaded. I am using this with an arduino DIY preamp as a volume control (of all things).there is nothing else like this on the market; its really good and now, its affordable.you need 4.7k pullups on the A and B lines. give the unit 5v and its normal quadrature after that.see my photo and video for a demo of what it can be like if you integrate this part into your system.

Learned this the hard way - Not always reliable on 5V. We use a lot of these, and we always do 12V nowadays. The nice part though, is that the output is (well...can't actually promise this) is open collector, so you can use a pull-up resistor to your controller's voltage, which might be 5V, and run your inputs like that while still powering it by 12V. Check your individual encoder though, because only god knows how the PCB inside is configured, or you..if you open it or measure the outputs on a meter.

It works great for my purpose, bench testing.
