The hardware itself is pretty straightforward. There is an Arduino Nano to run the speech recognition algorithm and a MAX9814 microphone amplifier to capture the voice commands.

The Raspberry Pi Pico is both faster and cheaper than the Arduino Nano, but the nano has better resources and community.

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...

The Nano ESP32 supports both Micropython and Arduino programming languages, providing a clear path for those already familiar with one platform to easily switch back and forth as needed.
