The output of the microphone is PDM or Pulse Density Modulation. Arduino has a PDM Library for working with devices like this. Until now, we have demonstrated the GIGA Display components by showing their output on the serial monitor. We could continue this trend with the microphone, displaying...

Girino - Fast Arduino Oscilloscope: I am a Physicist and the nicest part of working in this field is that I get to build my own instruments. With this way of thinking, I decided to build a homebrew Arduino Oscilloscope. This instructable was written with
You can use the not-operator (!) to swap 1 and 0. E.g.!digitalRead(pin)returns 0 when the button is not pressed, and 1 when the button is pressed. Extra: Direct port manipulation (advanced) DigitalRead, digitalWrite and pinMode are great and simple functions, but they are relatively ...
