Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals. There are the two basic ways to read a microcontroller’s digital input. With ...

An Arduino Uno or similar board will work perfectly. 2. Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3. LCD Display: To show the current settings and ...

At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, and 16×2 LCD providing an interface to control it over SPI. Unfortunately, the AD9833 doesn’t have ...

Here’s an inexpensive Arduino-based MP3 Jukebox (translated ... to this he added a custom face plate to host the character LCD, rotary encoder, two buttons, and to act as a grill for the ...

I have to thank one author of a rotary encoder decoder (Ben Buxton). While his code seemed overly complex to my untutored eye, for example creating a new data type, it did show Arduino-novice me two ...
