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)
|
|
})
|
|
```
|
|
|
|
```package
|
|
radio
|
