CircuitPython Digital Input Example - Blinking an LED using a button switch.
|
|
|
|
Update BUTTON_PIN to the pin to which you have connected the button (in the case of an external
|
|
button), or to the pin connected to the built-in button (in the case of boards with built-in
|
|
buttons).
|
|
|
|
For example:
|
|
If you connected a button switch to D1, change BUTTON_PIN to D1.
|
|
If using a CPX, to use button A, change BUTTON_PIN to BUTTON_A.
