3 Neopixels (WS2811) for the background lights. 2 for the rotary encoder 1 for the LCD screen (uses a lightguide and it makes a pretty homogeneous backlight)
The first 2 pixels are used for the encoder (one per side) the third one is for the backlight of the screen (and you’d better use it). The color order is Green, Red, Blue.

The encoder seems to make 4 pulses per direction and is a 90 degrees phase encoded on its two pins. All the inputs are put to GND in the encoder, so you have to use pull ups.
Human Machine Interface (HMI) specialist EAO has introduced an innovative Touch Encoder that integrates a touch-screen LCD display with a multi-function rotary switch and pushbuttons in a single product. The new innovation from Grayhill Inc streamlines Human Machine Interfaces (HMIs) used in medical electronics, audio/visual and specialist vehicle control applications. Instead of tweaking multiple knobs the new device enables users to fine-tune their equipment control while keeping their hands in a single position.
The multiple configuration options provided by the new Touch Encoder are configured using an intuitive iPad development kit app that provides access to tap, swipe, and rotation gestures and makes it easy to support custom layouts and multiple language options. Rugged, sealed and impact resistant, the new device will also be welcomed by engineers developing emerging control applications where intuitive control is paramount.
According to Robert Davies, Marketing Manager with EAO UK, replacing multiple buttons saves on unit price and tooling costs, while the simplified interface makes user training easier: “Grayhill’s intuitive tablet development app enables the user to personalise multi-touch gestures, generate images, customise the display, and even trigger the logic on the Touch Encoder – all without the help of a software engineer,” Davies said.
Grayhill, Inc. designs and manufacturers intuitive human interface components and solutions including optical encoders, rotary switches, keypads, joysticks and rugged touch screen displays. Visit www.grayhill.com to learn more about Grayhill’s products and capabilities

In our last tutorial, we examined how to create a menu for your Arduino project on a Nokia 5110 LCD, with push buttons to navigate through it. In today’s tutorial, we will build a modified version of it which will make use a rotary encoder (in place of the push buttons) for menu navigation.
A menu is one of the easiest ways through which users can interact with devices with diverse features. From Smartphones to PCs and even TVs, it is used in almost every electronic device with a screen and navigating through it is done usually by pressing certain buttons to move up/down, right/left and make selections. However, in some recent smart devices, either for aesthetics or for an improved form factor, a knob-like approach is employed for navigation. For today’s tutorial, we will explain how to create a menu with the same Knob style control, using a rotary encoder.
Rotary Encoders are used in several systems where precision and feedback in terms of rotational motion or angular position are required. By turning the shaft to the right or left, we either get an increase or decrease in value (depending on the configuration). One of the major advantages of rotary encoders is the fact that their rotation is limitless. If the maximum position, (which is 20 for the particular rotary encoder used in this tutorial) is reached, the device starts the position counting all over again while the value attached to the position continues to increase/decrease with every turn of the knob in the same direction. Another good feature which will be handy for this tutorial is that they come with buttons attached, so it can be clicked by pressing the knob and is recognized by the Arduino just as any other button or switch.
The schematics for today’s project is almost similar to the one of the last tutorial. We will take out the three push-buttons and add a rotary encoder. Connect the components as shown in the schematics below.
To simplify/reduce the amount of work we need to do, we will use four libraries. Two of the libraries; the Adafruit GFX library and the Nokia 5110 LCD library, will be used to interact with the display while the other two; the Encoder Library and the TimerOne library, will reduce the amount of code we write to interact with the rotary encoder. Each of the libraries can be downloaded via the links attached to them or installed via the Arduino Library Manager.
Next, we write the void setup() function. We start by declaring the pin to which the LCD’s backlight is connected (D7) as output and then proceed to create an encoder object before initializing the display and the rotary encoder, setting it to start at zero. We also create an interrupt routine which will be used to detect button press within any of the menu pages.
Up next is the void loop() function. This function is the most complex part of the whole code. The function basically creates the menu and uses the variables created initially to keep track of the previous, current and next state so when the rotary encoder is turned, it knows the right menu to display. The menu selection part of the code is also handled by a routine within the void loop() function.
Next, Data from the encoder is fed into a series of if-else statements which checks if the encoder was clicked or turned in a particular direction and which of the screens is currently being displayed to determine what action is to be done next. For instance, the first if statement checks if the menu is currently on page 1 and if the encoder is turned to the right (indicates up). If this is the case, it then checks the position of the menu cursor and adjusts it accordingly.
Verify your connections, by comparing with the schematics above, to ascertain that everything is as it should be. With that done, connect your board to the computer and upload the sketch to it. You should see the screen come on with the menu displayed. Try to turn the knob in different directions to navigate the menu and use the click feature of the knob to select an option.
