Test Result

Done uploading the code to the board, power on the board, you should see the 4-digit LED display the number. Shown below.

The analog value output by potentiometer is showed on the 4-digit LED display.
Press the button S3-A3, the 6 SMD LEDs will light up one by one like the flowing light, but 4-digit LED display is off.
Press the button S2-A2, the passive buzzer will beep and 4-digit LED display is still off.
Press the button S1-A1, 4-digit LED display will show the default number 0123.
