# Adafruit AS5600 Magnetic Angle Sensor
## Overview
Add rotational sensing - without a mechanical connection - with the **Adafruit AS5600 Magnetic Angle Sensor**. Featuring the classic [ams AS5600](https://ams-osram.com/products/sensor-solutions/position-sensors/ams-as5600-position-sensor), this board can sense a rotating N/S magnetic field up to 3mm away from the chip body. These sensors are often used to create 'frictionless' rotary encoders or potentiometers, without the risk of mechanical failure or noise. Magnetic angle sensors get the best of 'both worlds': like rotary encoders they can rotate freely 360 degrees around, and like potentiometers, they have absolute location detection.
All you need is a microcontroller or microcomputer with I2C - we have Arduino, Python and CircuitPython driver support. Then, identify the north and south of a magnet: we recommend a rare earth magnet. Note that many round magnets have the N/S on alternate 'coin face' sides, so you'll need to rotate it on the edge. Place the magnet near the middle of the chip and rotate it in place. The firmware will detect the magnetic field and report the angle from 0 to 359 with 0.1° precision and 0.4° accuracy.
To make usage plug-and-play, we added [SparkFun qwiic](https://www.sparkfun.com/qwiic)-compatible **[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt)** connectors for the I2C bus, **so you don't even need to solder the I2C and power lines.** Simply wire up to your favorite micro using a [STEMMA QT adapter cable.](https://www.adafruit.com/?q=stemma%20qt%20cable) The Stemma QT connectors also mean the AS5600 can be used with our [various associated accessories](https://www.adafruit.com/?q=JST%20SH%204). [QT Cable is not included, but we have a variety in the shop](https://www.adafruit.com/?q=stemma+qt+cable&sort=BestMatch).
Comes as a fully assembled breakout board a small bit of header. Some light soldering is required to attach the header for use on a breadboard.

## Pinouts
The I2C address is **0x36**.
## Power Pins
- **VIN** - this is the power pin. It can be powered by 3V or 5V. Give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V.
- **3Vo** - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like.
- **GND** - common ground for power and logic.
## I2C Logic Pins
- **SCL** - I2C clock pin, connect to your microcontroller's I2C clock line. This pin can use 3-5V logic, and there's a **10K pullup** on this pin.
- **SDA** - I2C data pin, connect to your microcontroller's I2C data line. This pin can use 3-5V logic, and there's a **10K pullup** on this pin.
- **[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt) -** These connectors allow you to connect to development boards with **STEMMA QT** (Qwiic) connectors or to other things with [various associated accessories](https://www.adafruit.com/?q=JST%20SH%204).
## PWM Output
- **OUT** - This is the analog/PWM output pin. In addition to reading data over I2C, you can read an analog or PWM output via this pin. In analog output mode, 0V corresponds to 0 degrees and VDD corresponds to 360 degrees. In PWM output mode, 0% duty cycle corresponds to 0 degrees and 100% duty cycle corresponds to 360 degrees.
## Direction Jumper
- **DIR** - On the back of the board is the direction jumper, labeled **DIR** on the board silk. This pin determines the direction of the magnetic rotation measurement. By default, the jumper is tied to ground, which sets the direction to clockwise. You can cut this jumper to pull it high to set the direction to counter-clockwise.
## Power LED and Jumper
- **Power LED -** In the upper left corner, above the STEMMA connector, on the front of the board, is the power LED, labeled **on**. It is a green LED.
- **LED jumper ** - This jumper is located on the back of the board and is labeled **LED** on the board silk. Cut the trace on this jumper to cut power to the " **on**" LED.
## PGO Pad
- **PGO** - On the back of the board, is a circular pad labeled **PGO** on the board silk. This is the program option pin and is used to calibrate and program the sensor. It is for **advanced use only** , since it changes the programming on the AS5600. More information on this pin and programming modes can be found in the datasheet, starting on page 22.

## CircuitPython and Python
It's easy to use the **AS5600 breakout** with Python or CircuitPython, and the [Adafruit\_CircuitPython\_AS5600](https://github.com/adafruit/Adafruit_CircuitPython_AS5600) module. This module allows you to easily write Python code to read data from the AS5600 with a magnet.
You can use this driver with any CircuitPython microcontroller board or with a computer that has GPIO and Python [thanks to Adafruit\_Blinka, our CircuitPython-for-Python compatibility library](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux).

- **Pi SCL** to **breakout** **SCL (yellow wire)**
- **Pi SDA** to **breakout** **SDA (blue wire)**
## Python Installation of AS5600 Library
You'll need to install the **Adafruit\_Blinka** library that provides the CircuitPython support in Python. This may also require enabling I2C on your platform and verifying you are running Python 3. [Since each platform is a little different, and Linux changes often, please visit the CircuitPython on Linux guide to get your computer ready](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux)!
Once that's done, from your command line run the following command:
- `pip3 install adafruit-circuitpython-as5600`
If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported!
## CircuitPython Usage
To use with CircuitPython, you need to first install the **Adafruit\_CircuitPython\_AS5600** library, and its dependencies, into the **lib** folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script.
Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, and copy the **entire** **lib** **folder** and the **code.py** file to your **CIRCUITPY** drive.
Your **CIRCUITPY/lib** folder should contain the following folders and file:
- **adafruit\_bus\_device/**
- **adafruit\_register/**
- **adafruit\_as5600.mpy**
## Python Usage
Once you have the library `pip3` installed on your computer, copy or download the following example to your computer, and run the following, replacing **code.py** with whatever you named the file:
`python3 code.py`
## Example Code
**If running CircuitPython:** Once everything is saved to the **CIRCUITPY** drive, [connect to the serial console](https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console) to see the data printed out!
**If running Python:** The console output will appear wherever you are running Python.
https://github.com/adafruit/Adafruit_CircuitPython_AS5600/blob/main/examples/as5600_simpletest.py
First, the AS5600 sensor is recognized over I2C. Then, in the loop, it waits to sense a magnet. Take your magnet and rotate it over the sensor. Once it detects the magnet, you'll see the 12-bit raw angle, 12-bit scaled angle and magnitude readings printed out to the serial console.

- **Board SDA** to **breakout** **SDA (blue wire)**
## Library Installation
You can install the **Adafruit\_AS5600** library for Arduino using the Library Manager in the Arduino IDE.
Click the **Manage Libraries ...** menu item, search for **Adafruit\_AS5600** , and select the **Adafruit AS5600** library:
If asked about dependencies, click "Install all".
If the "Dependencies" window does not come up, then you already have the dependencies installed.
Warning: If the dependencies are already installed, you must make sure you update them through the Arduino Library Manager before loading the example!
## Example Code
https://github.com/adafruit/Adafruit_AS5600/blob/main/examples/AS5600_basic/AS5600_basic.ino
Upload the sketch to your board and open up the Serial Monitor ( **Tools -\> Serial Monitor** ) at 115200 baud. You'll see the AS5600 recognized over I2C. Then, take a magnet and rotate it above the sensor. You'll see the raw angle and scaled angle printed out to the Serial Monitor, which are 12-bit values. If the magnet is too close or too far from the sensor, you'll see a warning printed to the Serial Monitor.

## WipperSnapper
## What is WipperSnapper
WipperSnapper is a firmware designed to turn any WiFi-capable board into an Internet-of-Things device without programming a single line of code. WipperSnapper connects to [Adafruit IO](https://io.adafruit.com/), a web platform designed ([by Adafruit!](https://www.adafruit.com/about)) to _display_, _respond_, and _interact_ with your project's data.
Simply load the WipperSnapper firmware onto your board, add credentials, and plug it into power. Your board will automatically register itself with your Adafruit IO account.
From there, you can add _components_ to your board such as buttons, switches, potentiometers, sensors, and more! Components are _dynamically _added to hardware, so you can immediately start interacting, logging, and streaming the data your projects produce without writing code.
If you've never used WipperSnapper, click below to read through the quick start guide before continuing.
[Quickstart: Adafruit IO WipperSnapper](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper)
## Wiring
First, wire up a AS5600 to your board exactly as follows. Here is an example of the AS5600 wired to an [Adafruit ESP32 Feather V2](https://www.adafruit.com/product/5400) using I2C [with a STEMMA QT cable (no soldering required)](https://www.adafruit.com/product/4210)
- **Board 3V** to **sensor VIN (red wire on STEMMA QT)**
- **Board GND** to **sensor GND (black wire on STEMMA QT)**
- **Board SCL** to **sensor SCL (yellow wire on STEMMA QT)**
- **Board SDA** to **sensor SDA (blue wire on STEMMA QT)**
## Usage
Connect your board to Adafruit IO Wippersnapper and **[navigate to the WipperSnapper board list](https://io.adafruit.com/wippersnapper).**
On this page, **select the WipperSnapper board you're using** to be brought to the board's interface page.
If you do not see your board listed here - you need [to connect your board to Adafruit IO](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper) first.
On the device page, quickly **check that you're running the latest version of the WipperSnapper firmware**.
The device tile on the left indicates the version number of the firmware running on the connected board.
- **If the firmware version is green with a checkmark -** continue with this guide.
- **If the firmware version is red with an exclamation mark "!" -** [update to the latest WipperSnapper firmware](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper) on your board before continuing.
Next, make sure the sensor is plugged into your board and click the ** I2C Scan ** button.
You should see the AS5600's default I2C address of `0x36` pop-up in the I2C scan list.
### I don't see the sensor's I2C address listed!
First, double-check the connection and/or wiring between the sensor and the board.
Then, reset the board and let it re-connect to Adafruit IO WipperSnapper.
With the sensor detected in an I2C scan, you're ready to add the sensor to your board.
**Click the New Component button or the + button** to bring up the component picker.
Adafruit IO supports a large amount of components. To quickly find your sensor, type `AS6500` into the search bar, then select the **AS6500** component.
On the component configuration page, the AS5600's sensor address should be listed along with the sensor's settings.
The **Send Every** option is specific to each sensor's measurements. This option will tell the Feather how often it should read from the AS5600 sensor and send the data to Adafruit IO. Measurements can range from every second to every 24 hours.
For this example, set the **Send Every ** interval to every 5 seconds. You can update it later using the settings cog at the end of the component row on the device page.
Your device interface should now show the sensor components you created. After the interval you configured elapses, WipperSnapper will automatically read values from the sensor(s) and send them to Adafruit IO.
Warning: A diametrically magnetized magnet must be positioned above the AS5600 sensor, centered over the chip with an air gap of 0.5-3mm.
If your sensor only shows a value of **null** , then try looking at the serial monitor for your device (it writes debugging log information to a serial port), or using another magnet.
To view the data that has been logged from the sensor, click on the graph next to the sensor name.
Here you can see the feed history and edit things about the feed such as the name, privacy, webhooks associated with the feed and more.
