1.2. Sample Projects

1.3. Project 01: Control the on/off of onboard LEDs with buttons.

from Pico_ed import *     #import file
from machine import Pin

while True:   
    if ButtonA.is_pressed():   #Detect if button A is pressed, if yes, return 1. 
        led.on()    #Use this method to light on the LEDs. 
    if ButtonB.is_pressed():  #Detect if button B is pressed, if yes, return 1. 
        led.off()   #Use this method to turn off the LEDs.

1.4. Result

Press button A to light on the LED and button B to turn it off.

1.5. Project 02: Control to display numbers or letters on the LEDs screen with buttons.

from Pico_ed import *     #import file
from machine import Pin

while True:   
    if ButtonA.is_pressed():   #Detect if button A is pressed, if yes, return 1. 
        display.show(1234567890)   #Use this method to scroll display the nummbers on the LEDs screen. 
       # Use method: display.show(numbers)
    if ButtonB.is_pressed():  #Detect if button B is pressed, if yes, return 1. 
        display.show("abcdefghijklmnopqrstuvwxyz")   #Use this method to scroll display the letters on the LEDs screen. 
        #Use method: display.show("letters")

1.6. Result

Press button A to display 1234567890 on the LEDs screen and button B to display abcdefghijklmnopqrstuvwxyz.

1.7. Project 03: The Music Player

from Pico_ed import *     #import file
from machine import Pin

while True:   
    if ButtonA.is_pressed():   #Detect if button A is pressed, if yes, return 1. 
        music.phonate("1155665-4433221-5544332-5544332-1155665-4433221")   #Use this method to play music and the numbers are equivalent to different tones. 
        #Use method   music.phonate("numbered musical notation")

1.8. Result

Press button A to play music.

1.9. Project 04: Light on the LED connecting to P1.

Hardware Connections

Program

from Pico_ed import *     #Program as this way
from machine import Pin

p1 = Pin(pin.P1, Pin.OUT)   #  Set the pins in output mode, enter with the number of pin.P. 
while True:   
    if ButtonA.is_pressed():   #Detect if button A is pressed, if yes, return 1.
        p1.value(1) #P1 pin up 
    if ButtonB.is_pressed():  #Detect if button B is pressed, if yes, return 1. 
        p1.value(0)  #P1 pin down

1.10. Result

Press button A to light on the LED and button B to turn it off.
