STEP 15: We need to update our graph every second, not every two!
The second parameter of an interval event specifies how many seconds should pass before it runs again.
- In the very last line of code, find where it says stage.event_interval(interval,·2)¶ .
- Change the second parameter from 2 to 1. This will make sure our interval event runs every second!
- Click Run. Then click Submit and Next to move on.
microbit = codesters.Microbit()
microbit.show_string("hello")
data = microbit.get_temp()
microbit.show_number(data)
data_list = []
time_list = []
my_display = codesters.ScatterPlot(time_list, data_list)
time = 0
def interval():
data = microbit.get_temp()
data_list.append(data)
global time
time_list.append(time)
my_display.update(time_list, data_list)
time += 1
stage.event_interval(interval, 2)
