Make

Turn a piece of cardboard into an milk carton robot!

Duration: ~45 minutes

Step 1: Cutting the lip

Step 2: Cutting the mouth

Step 3: Cutting the teeth

Step 4: Attaching the mouth

Step 5: Attaching the mouth wood sticks

Step 6: Mounting the servo

Step 7: Connecting the mouth to the servo

 

Well done! Let’s move to programming the micro:bit to move the mouth.

Code

Add code to make the Milk Carton Robot move.

Duration: ~15 minutes

Step 1: wire up the servo

Follow the instructions in servo 101 manual to connect the servo to the micro:bit.

Step 2: code light sensor

Code the lightsensor on the micro:bit to control the servo.

It works but your servo might be trying to move too much. Let’s calibrate it.

Step 3: calibrate the servo

Download the servo calibration program to determine to opening and closing angles of the servo for your robot.

   我們將使用pins.map將光照範圍0,255映射到角度範圍，[關閉，打開]。

Connect

Remote control your Milk Carton Robot with another micro:bit

Duration: ~30 minutes

您將需要2x micro:bit這部分。 通過使用收音機，我們可以使Milk Carton Monster由另一個微處理器控制： 將下面的代碼下載到“牛奶紙箱怪物”上的micro：bit，另一個“控制器”micro：bit。 如果按A，牛奶紙箱怪物會動一次。
