I would recommend moving show_badge and auto_dim out of the loop and then allowing something like pressing the start button to switch back to badge mode.


while True:
pybadger.auto_dim_display(delay=10)
if pybadger.button.a:
pybadger.show_business_card(image_name="Blinka.bmp", name_string="Blinka", name_scale=2,
email_string_one="blinka@", email_string_two="adafruit.com")
elif pybadger.button.b:
pybadger.show_qr_code(data="https://circuitpython.org")
elif pybadger.button.start:
pybadger.show_badge(name_string="Blinka", hello_scale=2, my_name_is_scale=2, name_scale=3)
