Once your masterpiece is complete, you can compile your script and run it on your micro:bit.
## Requirements
You need the following things to transfer and run a script on your micro:bit:
* A-Male to Micro USB cable to connect your computer to your micro:bit. This is the same cable that is commonly used to connect a smart phone to a computer.
* a PC running Windows 7 of later, or a Mac running OS X 10.6 or later
* access to the Internet
## Step 1: Connect your micro:bit to your computer
First, connect the micro:bit:
1. Connect the small end of the USB cable to the micro USB port on your micro:bit.
2. Connect the other end of the USB cable to a USB port on your computer.
Your computer should recognise your micro:bit as a new drive. On computers running Windows, MICROBIT appears as a drive under Devices and drives. On a Mac it appears as a new drive under Devices.
4. When prompted, choose to save the compiled file on your computer (or anywhere other than the micro:bit). Depending on which browser you are using, the download will adopt the download behaviour of that particular browser.
2. If you're using Windows, you can use **Send to** as described below.
3. The LED on the back of your micro:bit flashes during the transfer (which should only take a few seconds).
4. Once transferred, the code will run automatically on your micro:bit. To rerun your program, press the reset button on the back of your micro:bit. The reset button automatically runs the newest file on the micro:bit.
**Send to**: If you're using Windows you use *Send to* in File Explorer:
- In File Explorer, right-click on the hex file (created in Step 2 above), choose **Send to**, and then **MICROBIT**.
By copying the script onto the 'MICROBIT' drive, you have programmed it into the flash memory on the micro:bit, which means even after you unplug the micro:bit, your script will still run if the micro:bit is powered by battery.
## Troubleshooting
You can’t drag and drop more than one hex file at once onto your micro:bit. If you try to drag and drop a second hex file onto your micro:bit before the first file has finished downloading, then the second file may fail in different ways.
When the first program has been written to the micro:bit, the drive will disengage. If you drag and drop a second file at this point it may not find the drive and the second write will fail.
The errors may look like this:
**Windows**
**Mac**
Or it may appear that there are two hex files on your micro:bit so the micro:bit won’t be able to run multiple files. To rectify this, unplug your micro:bit and plug it in again. Make sure that your micro:bit appears as MICROBIT and not MAINTENANCE.
