+title: 'Arduino Lab for MicroPython (online)'
+description: 'The Arduino Lab for MicroPython is an online code editor for writing and loading MicroPython scripts.'  
+author: 'Karl Söderby'  
+---
+
+The [Arduino Lab for MicroPython]() is an online code editor that allows you to load MicroPython scripts to your Arduino board. This editor is part of the [Arduino Cloud](), and is free to use for everyone.
+
+In this tutorial, we will take a look at how we can access it, and test it out by writing a simple script.
+
+***Note that this tutorial does not go in depth on how the Arduino Lab for MicroPython works. For more details, you can visit the [guide to the Arduino Lab for MicroPython]().***
+
+## Requirements
+
+- **Google Chrome** - this is currently the only supported browser.
+- [Arduino Cloud account registered]()
+- [A MicroPython compatible board]()
+
+## Setting Up
+
+***To follow these steps, you will need to have MicroPython installed on your board. Haven't done this yet? Don't worry, check out the [Installing MicroPython]() guide.***
+
+Setting up the online environment is quick and easy. Follow the steps below to achieve it:
+
+1. Go to [Arduino Cloud](https://app.arduino.cc/) and log in / create an account.
+2. Navigate to [lab-micropython.arduino.cc](https://lab-micropython.arduino.cc/). This is accessible through the cloud interface, under **Resources > Online Lab for MicroPython**.

+3. Click on the **"Connect"** button, and select our board from the list.
+   ![Select your board](assets/connect-board.png)
+4. With the board connected, in the text area, copy and paste the following:
+   ```python
+   print("Hello World!")
+   ```
+
+We should now see `Hello World!` printed in the REPL.
+
+## Troubleshooting
+
+- If the "RUN" button is faded out, it means the board is not connected. Click the "Connect" button to get a list of available boards connected.
+- Make sure MicroPython is installed on your board.
+- If you have recently installed MicroPython on your board, try resetting the board by pressing the reset button (once), or disconnect & reconnect the USB cable.
