+### @description code to make the Milky Monster alive
+
+### ~avatar avatar
+
+Add code to make the Milky Monster move.
+
+### ~
+
+## Duration: ~30 minutes
+
+## Step 1: calibrate servo
+
+In order for the Milky Monster to move, the @boardname@ needs to command the servo to go between ``0`` and ``180`` degrees at a certain pace. In the code below:
+- the user pressed button ``A`` to switch the servo to 180 degrees (to close the mouth of Milky Monster). 
+- the user pressed button ``B`` to switch the servo to 0 degrees (to open the mouth of Milky Monster). 
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    pins.servoWritePin(AnalogPin.P0, 180)
+    basic.showNumber(180)
+})
+input.onButtonPressed(Button.B, () => {
+    pins.servoWritePin(AnalogPin.P0, 0)
+    basic.showNumber(0)
+})
+basic.showString("calibrate")
+
+```
+
+## Step 2: attach rotor
+
+The servo should be positioned on 180 degrees **before** attaching the rotor to it. This is to make sure the mouth of the Milky Monster will be closed once the servo reaches 180 degrees. 
+
+### ~ hint
+
+You may use a philips scew driver to attach the rotor to the servo.

+
+## Step 3: check calibration
+
+When the user pressed ``A`` the servo rotor should be in 'up' position.

+
+## Step 4: connect cord to rotor
+
+Connect the cord to the servo rotor while mouth of Milky Monster is **closed**.

+## Step 5: connect cables to @boardname@
+
+Connect cables from @boardname@ to the servo and place the battery.

+
+## Step 6: code light sensor
+
+Code the lightsensor on the @boardname@ to control the servo.
+
+```blocks
+basic.forever(() => {
+    pins.servoWritePin(AnalogPin.P0, input.lightLevel())
+    led.plotBarGraph(
+        input.lightLevel(),
+        0
+    )
+})
+```
+
+## Step 6: Ready!
+
+Your Milky Monster is ready!
