This breakout makes the ANO rotary encoder wheel much easier to use in a breadboard or wired prototype. The encoder is a distinctive navigation control, with a clicky scroll-wheel feel reminiscent of early iPod interfaces.
The board converts the encoder’s unusual pin set into a straightforward header strip, and this version comes with the encoder already soldered in place.
There are no pull-up or pull-down resistors on the PCB, so use your microcontroller’s button and rotary encoder library or hardware support to interface with the pins. You’ll need 7 GPIO total: 5 button inputs and 2 rotary encoder pins.
Two COMmon pins are also provided and can be set to ground or VCC. They are usually tied to ground so you can use your microcontroller’s internal pull-ups; Adafruit’s example code uses GPIO for the COM pins and sets them as outputs for simpler wiring, but they can also be wired directly.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
