+# Chassis
+### @description Building the cardboard inchworm
+
+### ~avatar avatar
+
+Turn a piece of cardboard into an inchworm!
+
+### ~
+
+## Duration: ~45 minutes
+
+## Materials
+  * Cardboard
+  * Scissors or cutters
+  * glue gun or tape
+  * 1 paper clip
+
+## Step 1: cardboard
+
+Cutout a cardboard rectangle. You can use the @boardname@ as a ruler to figure out the size.
+
+![](/static/mb/projects/inchworm/chassis1.jpg)
+
+## Step 2: center fold
+
+Fold the cardboard in half over the short edge.
+
+![](/static/mb/projects/inchworm/chassis2.jpg)
+
+## Step 3: legs
+
+Fold each end so they rest flat on the ground.
+
+![](/static/mb/projects/inchworm/chassis3.jpg)
+
+## Step 4: front teeth
+
+Fold each corners on one end of the cardbard. This will be the front of the inchworm which is supposed to grip the ground.
+
+![](/static/mb/projects/inchworm/chassis4.jpg)
+
+## Step 5: back teeth
+
+Using a scissor or a cutter (watch the fingers!), cut out various strips in the other edge. Fold one after the other.
+
+![](/static/mb/projects/inchworm/chassis5.jpg)
+
+## Step 6: mounting the board
+
+Using tape or a glue gun, mount the @boardname@ on one side and the microservo on the cardobard.
+
+![](/static/mb/projects/inchworm/chassis6.jpg)
+
+## Step 7: mounting the servo
+
+Attach the servo on the **edge** of the other cardboard side.
+
+![](/static/mb/projects/inchworm/chassis7.jpg)
+
+## Step 8: Cable clean up (optional)
+
+Use tape to route the cables nicely on the inchworm.
+
+![](/static/mb/projects/inchworm/chassis8.jpg)
+
+## Step 9: attaching paper clip to servo
+
+Unfold a paper clip and attach it to the servo arm.
+
+![](/static/mb/projects/inchworm/clip2.jpg)
+
+## Step 10: attaching paper clip to cardboard
+
+Slide the folder paper clip into the cardboard, and use tape to secure it. 
+You might need to toy around with the size of the clip so that the servo rotation opens the inchworm sufficiently.
+
+![](/static/mb/projects/inchworm/clip3.jpg)
+
+
+## Step 11: it's ready!
+
+Your inchworm is ready!

+# Code
+### @description code to make the inchworm alive
+
+### ~avatar avatar
+
+Add code to make the inchworm move.
+
+### ~
+
+## Duration: ~30 minutes
+
+## Step 1: walk forever
+
+In order for the inchworm 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 launch the inchworm.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    pins.servoWritePin(AnalogPin.P0, 0)
+    basic.pause(500)
+    pins.servoWritePin(AnalogPin.P0, 180)
+    basic.pause(500)
+});
+```
+
+### ~ hint
+
+You may have noticed that the inchworm can be rather slow or simply won't move. Try to improve the design of your legs, teeth
+so that the inchworm goes as fast as possible. Trying it on carpet also great helps avoiding skidding.
+
+### ~
+
+## Step 2: radio controlled inchworm
+
+You will need 2 @boardname@ for this part. By using the radio, we can make the inchworm controlled by another @boardname@.
+Download the code below to the @boardname@ on the inchworm and another "controller" @boardname@. Whenere A is pressed, the inchworm will move once.
+
+```blocks
+radio.onDataPacketReceived(({receivedNumber}) => {
+    pins.servoWritePin(AnalogPin.P0, 0)
+    basic.pause(500)
+    pins.servoWritePin(AnalogPin.P0, 180)
+    basic.pause(500)
+})
+input.onButtonPressed(Button.A, () => {
+    radio.sendNumber(0)
+})
+```

+# Preparing the servo
+### @description Connecting the servo to crocodile clips
+
+### ~avatar avatar
+
+Equip the microservo with crocodile clips.
+
+### ~
+
+## Duration: ~30 minutes
+
+## Materials
+  * Cutting pliers or wire cutter
+  * Tape (masking, duct tape, and/or packing tape)
+  * 3 crocodile clips, yellow, red and black.
+  * 1 micro servo 9g (SG90)
+
+## Using a microservo with the @boardname@
+
+The @boardname@ provides just enough current to operate the SG90 microservo. 
+The servo requires 3 connections: GND, 3V and a logic pin. 
+In this tutorial, we will equip the servo with crocodile clips to make it easier to use. 
+However, you could also use a shield or female to crocodile clips to acheive the same effect.
+
+If you are running a class or activity, you should consider preparing all servos before hand.
+
+### ~ hint
+
+Kitronik wrote an excellent in-depth guide about using servos with the @boardname@. 
+Check it out at https://www.kitronik.co.uk/blog/using-bbc-microbit-control-servo/ .
+
+### ~
+
+## Step 1: cutout the connector
+
+Using the cutting pliers, cut out the dark plastic connector.
+
+![](/static/mb/projects/inchworm/servo1.jpg)
+
+## Step 2: strip out cables
+
+Using the plier or a wire stripper, strip the plastic from the cables.
+
+![](/static/mb/projects/inchworm/servo2.jpg)
+
+## Step 3: threading the servo cablers
+
+Thread the servo cables.
+
+![](/static/mb/projects/inchworm/servo3.jpg)
+
+## Step 4: crocobile clip claps
+
+Cut a crocodile cable in two and strip out the casing. 
+If possible try to use the same cable colors as the servo!
+
+![](/static/mb/projects/inchworm/servo4.jpg)
+
+## Step 5: thread cables together
+
+Place the cables next to each other
+
+![](/static/mb/projects/inchworm/servo5.jpg)
+
+... and thread them together.
+
+![](/static/mb/projects/inchworm/servo6.jpg)
+
+### ~ hint
+
+It is very **important** to ensure that there is a good connection between the 2 cables.
+If the connection is weak, the microservo will not receive enough current and it will not work.
+If you have access to a soldering iron, we strongly recommend to solver this connection.
+
+### ~
+
+## Step 4: protect the connection
+
+Protect the connection with electrical or duct tape.
+
+![](/static/mb/projects/inchworm/servo7.jpg)
+
+## Step 5: repeat for all cables
+
+Repeat the same process until all cables are connected.
+
+![](/static/mb/projects/inchworm/servo8.jpg)
+
+## Step 6: testing!
+
+It's time to test that your connection are all proper and that the servo will function **when the @boardname@ is powered by battery**.
+
+* Connect the microservo to the @boardname@. Black cable on ``GND``, red cable on ``3V`` and remaining cable on ``P0``.
+
+![](/static/mb/projects/inchworm/circuit1.jpg)
+
+### ~ hint
+
+When attaching the crocodile clips to the pins, don't hesitate to grab the side of the board with the jaws.
+
+![](/static/mb/projects/inchworm/circuit2.jpg)
+
+### ~
+
+* Download the following code to your @boardname@
+
+```blocks
+let a = 0
+basic.forever(() => {
+    a = input.acceleration(Dimension.X)
+    pins.servoWritePin(AnalogPin.P0, pins.map(
+        a,
+        -512,
+        512,
+        0,
+        180
+    ))
+})
+```
+
+* When powered by USB, make sure that the servo moves when you tilt the board.
+* When powered by batteries **only**, make sure that the servo moves when you tilt the board.
+
+If your servo seems to sutter and stay stuck at a particular position, it means that it is not receiving enough power.
+This is probably due to a weak connection or low battery level. Check each connection and check your batteries.
