    Inspired by an automatic Pokemon shiny capturer, my friend and I are determined to make something similar. However, we had some questions with regard to the signal required to for the 3DS to detect a "button press".

    In the original creators video, the following implementation was used:

    By my understanding, the Arduino is capable of outputting a PWM signal causing some confusion as to why the a hex inverter is needed to create the PWN signal.

    We were also wondering if the low-pass filter is simply used to lower the voltage of the signal?

    Finally, since I am having trouble finding documentation on 3DS button logic, I am also unsure of what my final output signal needs to be to be recognized as a "button press".

    Any help with our project would be greatly appreciated!

    Like it says the hex inverter is used as a level shifter, power it at 1.8v and you will get 1.8V out even if you put 5Vin. The Arduino is doing the PWM.

    I couldn't be bothered to watch the video (I much prefer a written description to a video) so I'm not sure what the low pass filter is used for.
