Optionally put a 10 mm furniture coaster sticker on the end of the arm, where the button will be pressed
Wire the Arduino to the stepper motor & controller board as seen in Thing photo
Firmware
Open the attached .ino sketch file in Arduino IDE
In Arduino IDE: Sketch -> Include Library -> Manage Libraries.... Then search and install accelstepper (currently 1.59.0)
Customize parameters like presses per second, maximum presses
Upload sketch file to program the Arduino
Push my buttons already
Clip the mount onto the top of the Switch (a little groove guides it to sit between the console and the right joycon)
Move the arm into position above the button
Go to the part of the Switch game that requires button pressing
Power Arduino and stepper motor assembly (5v USB or power supply)
Sit back and relax
