makecode上的python
使LED隨著板子移動而變動
old_x = 0
old_y = 0
def on_forever():
basic.pause(20)
x = input.acceleration(Dimension.X)
y = input.acceleration(Dimension.Y)
global old_x
global old_y
led_x = Math.map(x, -1000, 800, 0, 4)
led_y = Math.map(y, -1000, 800, 0, 4)
if led_x == 5:
led_x = 4
if led_y == 5:
led_y = 4
if old_x != led_x or old_y != led_y:
led.unplot(old_x, old_y)
led.plot(led_x, led_y)
old_x = led_x
old_y = led_y
basic.forever(on_forever)
使用Thonny的micropython
from microbit import *
import microbit
old_x = 0
old_y = 0
while True:
sleep(20)
x = accelerometer.get_x()
y = accelerometer.get_y()
led_x = (x - (-1024) ) /410
led_x = int(led_x)
led_y = (y - (-1000) ) /410
led_y = int(led_y)
if led_x == 5:
led_x = 4
if led_y == 5:
led_y = 4
if old_x != led_x or old_y != led_y:
microbit.display.set_pixel(old_x, old_y, 0)
microbit.display.set_pixel(led_x, led_y, 9)
old_x = led_x
old_y = led_y
