 # On Start
 An event that runs when the program starts.
 The ``on start`` is a special event that runs when the program starts, before any other event. 
 Use this event to initialize your program.
 ## Example
 In this example, ``on start`` sets a dimmer brightness on the screen and the button handler shows a string.
 ```blocks
 input.onButtonPressed(Button.A, () => {
    basic.showString("Hello!")
 })
 led.setBrightness(50)
 ```
 ## What about JavaScript?
 ``on-start`` only exists in the block editor. In JavaScript, all code executes sequentially from the first line.

 # 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!

 # 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/servotrim.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.

 which can be received and acted upon by anyone in range with a suitable device and software, typically a smartphone and application.
 There are various beacon message formats, which define the way Bluetooth advertising packets are used as containers for beacon data. 
 iBeacon is Apple's beacon message format. Eddystone comes from Google.

 ```sig
 bluetooth.advertiseUidBuffer(pins.createBuffer(16), 7, true);
 ```
 ### Parameters
 * ``buffer`` - a 16 bytes buffer containing the namespace (first 10 bytes) and instance (last 6 bytes).
 * ``power`` - a [number](/reference/types/number) representing the power level between 0 (short) and 7 (maximum range).
 * ``connectable`` - a [boolean](/blocks/logic/boolean) indicating whether or not the micro:bit should accept connections.

 ### Eddystone
 Bluetooth beacons are used to indicate proximity to a place or object of interest. 
 Beacons use Bluetooth advertising to broadcast a small amount of data, 
 which can be received and acted upon by anyone in range with a suitable device and software, typically a smartphone and application.

 ## ~
 ```sig
 bluetooth.advertiseUid(42, 1, 7, true);
 ```
 ### Parameters
 * ``namespace`` last 4 bytes of the namespace uid (6 to 9)
 * ``instance`` last 4 bytes of the instance (2 to 5)
 * ``power`` - a [number](/reference/types/number) representing the power level between 0 (short) and 7 (maximum range).
 * ``connectable`` - a [boolean](/blocks/logic/boolean) indicating whether or not the micro:bit should accept connections. 
 ## Encoding
 The bytes of ``namespace`` and ``instance`` are encoded to generate the 10 bytes UID namespace and 6 bytes UID instance.
 ```
 UID namespace: [0, ..., namespace]
 UID instance: [0, ..., instance]
 ```

 # Getting started
 ### Step 1
 Place blocks in the workspace to scroll text on the screen.
 ```blocks
 basic.showString("Hi!")
 ```
 ### Step 2
 Transfer your code in your @boardname@! Click the **Download** button
 and follow the instructions.
 ANIMATEDGIF
 ### Step 3
 Great, the text scrolled! But then it stopped.
 Let's make it scroll when button **A** is pressed.
 ```block
 input.onButtonPressed(Button.A, () => {
    basic.showString("Hi!")
 });
 ```
 ### Step 4
 Transfer your code in your @boardname@ and try pressing **A**.
 ANIMATEDGIF
 ### Step 5
 Place more blocks to display a smiley when button **B** is pressed.
 Download your code and try it!
 ```block
 input.onButtonPressed(Button.B, () => {
    basic.showLeds(`
    # # . # #
    # # . # #
    . . . . .
    # . . . #
    . # # # .
    `)
 })
 ```
 ### Step 6
 Drag more blocks to display a frownie when @boardname@ is shaken.
 Download your code and try it!
 ```block
 input.onGesture(Gesture.Shake, () => {
    basic.showLeds(`
    # # . # #
    # # . # #
    . . . . .
    . # # # .
    # . . . #
    `)
 })
