Sound Generation and Musical Microcontrollers - Electronics with Becky Stern | DigiKey

In this video, @BeckyStern explores sound generation and musical microcontrollers. Whether you’re building a talking robot or your own DIY synthesizer, this episode will help you choose the right parts for adding audio to your projects.

In past episodes of the Electronics with Becky Stern YouTube series, Becky covered topics like addressable LEDs and microcontroller selection. This video builds on those skills but instead uses piezos, speakers, audio playback modules to craft interactive audio.
