Change the value of a variable
|

### Declare a variable
|
|
|
|
Use the assignment operator to set the value of a [variable](/microbit/reference/variables/var). Change the value of a variable from 0 to 1 using the change item block. Like this:
|
|
|
|
```blocks
|
|
let x = 0
|
|
x += 1
|
|
```
|
|
|
|
### Example
|
|
|
|
Use the assignment operator to set the value of a [variable](/microbit/reference/variables/var). Change the value of a variable from 0 to 1 using the change item block. Then display the new value of the variable on the LED screen. Like this:
|
|
|
|
```blocks
|
|
let x = 0;
|
|
x += 1;
|
|
basic.showNumber(x);
|
|
```
|
|
|
|
