SunFounder Thales Kit for Raspberry Pi Pico, Release 1.0
Buttons require pull-up resistors or pull-down resistors. If there is no pull-up or pull-down resistor,
the main controller may receive a ‘noisy’ signal which can trigger even when you’re not pushing the
button.
6. Connect the negative power bus of the breadboard to Pico’s GND.
Code
When the button is pressed, the current will flow from 3V3 through the button to GP14, in other words, GP14 will
read a high-level signal ‘1’; otherwise, it will read a low-level signal ‘0’.
import machine
import utime
button = machine . Pin( 14 , machine . Pin . IN)
while True :
if button . value() == 1 :
print ( "You pressed the button!" )
utime . sleep( 1 )
Pull-up Working Mode
Next is the wiring and code when the button in the pull-up working mode, please try it.
