Pageturner

I designed a pageturner with a Raspberry Pi Pico for dirct connection to my PC. With the current firmware it simulates a keyboard arrow left and right. You can modify this easy with Thonny.

Circuit Python code:

import time

import board
import usb_hid
from adafruit_hid.keyboard import Keyboard
from adafruit_hid.keyboard import Keycode

btn1_pin = board.GP16
btn2_pin = board.GP18

keyboard = Keyboard(usb_hid.devices)

btn1 = digitalio.DigitalInOut(btn1_pin)
btn1.direction = digitalio.Direction.INPUT
btn1.pull = digitalio.Pull.DOWN
btn2 = digitalio.DigitalInOut(btn2_pin)
btn2.direction = digitalio.Direction.INPUT
btn2.pull = digitalio.Pull.DOWN

while True:
   if btn1.value:
       print("Knop1 ingedrukt")
       keyboard.press(Keycode.LEFT_ARROW)
       time.sleep(0.1)
       keyboard.release(Keycode.LEFT_ARROW)
   if btn2.value:
       print("Knop2 ingedrukt")
       keyboard.press(Keycode.RIGHT_ARROW)   
       time.sleep(0.1)
       keyboard.release(Keycode.RIGHT_ARROW)
   time.sleep(0.1)

You need to install the Adafruit_HID library adafruit/Adafruit_CircuitPython_HID: USB Human Interface Device drivers.
