Learning goals:
In this lesson, we will learn the using of a single pin. When we clamp the GND with one end of the alligator clip and the pin0 pin with the another end of the alligator clip, the micro:bit dot matrix will display smile expression, Otherwise micro:bit dot matrix will display sad expression.
Code:
from microbit import*
while True:
if pin0.is_touched():
display.show(Image.HAPPY)
else:
display.show(Image.SAD)
Programming and downloading：
1.You should open the Mu software, and enter the code in the edit window, , as shown in Figure 7-1.
Note! All English and symbols should be entered in English, and the last line must be a space.
Figure 7-1
2. As shown in Figure 7-2, you need to click the Check button to check if our code has an error. If a line appears with a cursor or an underscore, the program indicating this line is wrong.

4. After the download is complete, you can see that the sad expression on the micro:bit dot matrix, as shown in Figure 7-4. When we clamp the GND with one end of the alligator clip and the pin0 pin with the another end of the alligator clip, the micro:bit dot matrix will display smileexpression, as shown in Figure 7-5.
