# Activity and  Motion

We are going to use a variables to create a jump counter. The  variables are created by the programmer and will store the number of times the system  senses a jump using the  accelerometer

```
When A Button is pressed 
    score = 0

//create the new variable score
```

The accelerometer is an electro-magnetic device that can sense motion or vibrations - everytime it senses motion we want to increase the score by 1. So the input is the `shake of the accelerometer` 

```
On Shake
   set score = score + 1
   
```

#### Now add some customization:

* [ ] When B Button is pressed display the score
* [ ] Create a `high score variable` 
  * [ ] Forever if score > high  score 
    * [ ] set `high score = score`
    * [ ] Display new high score on LED Grid
