This is the answer key for the [blink quiz](/microbit/lessons/blink/quiz).
|
|
|
|
## 1. Describe what `plot` does?
|
|
|
|
Answers will vary. In general, plot refers to the code that turns on a specific LED. We specify the LED using x, y coordinates.
|
|
|
|
## 2. Draw which LED is ON after running this code
|
|
|
|
```blocks
|
|
led.plot(2, 2)
|
|
|
|
```
|
|
|
|
|
|
|
|
By default, the position of an LED on *Blink Tutorial* is set to the centre of the screen. This code turns on the centre LED
|
|
|
|
## 3. Draw which LED is ON after running this code
|
|
|
|
```blocks
|
|
led.plot(0, 0)
|
|
|
|
```
|
|
|
|
|
|
|
|
This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using x, y coordinates.
|
|
|
|
* ``x`` - the x coordinate or horizontal position (0)
|
|
* ``y`` - the y coordinate or vertical position (0)
|
|
|
|
## 4. Draw which LED is ON after running this code
|
|
|
|
```blocks
|
|
led.plot(4, 4)
|
|
|
|
```
|
|
|
|
|
|
|
|
This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using ``x``, ``y`` coordinates.
|
|
|
|
* ``x`` - the x coordinate or horizontal position (4)
|
|
* ``y`` - the y coordinate or vertical position (4)
