# B -Servo Motor

### Servo Motor Activity

In this activity we are using the Servo Motor we will be able to visualize different scenarios for different time periods of projected mean annual precipitation.

* Recent past(2000-2020).
* Immediate future ( 2030-2050).
* Near future(2060-2080).

### **Functionality**

#### **micro:bit A Button**

* Cycle through the three different **time** **periods** programmed.
* Each time the period is represented by a lit LED on the micro:bit.

#### micro:bit B Button

* Cycle through the three different **years** within the time period.
* Each year is represented by a lit LED on the micro:bit.

#### **micro:bit A+B Buttons**

* Toggle between low and high-carbon **scenarios** for the Immediate Future and the Near Future scenarios.

#### Servo Motor

* Display different precipitation levels on the pre-printed cardboard cutout.
