**Challenge 0**

Welcome! This [guided tutorial](/pxjkww) introduces the basic show string method on the micro:bit.

Let's show the string 'Hello' on the LED screen. The string will scroll one character at a time from left to right.

```
basic.showString("Hello ", 150)
```

**Challenge 1**

Now, let's show the string 'World' on the LED screen.

```
basic.showString("Hello ", 150)
basic.showString("World", 150) // ***
```

**Challenge 2**

Let's display another string to introduce yourself!

After 'Hello World' we want to display the string 'My name is '.

```
basic.showString("Hello World", 150)
basic.showString("Good Night World ", 150) // ***
```

**Challenge 3**

Add Micro's response to Good Night World!
