Amazon Alexa Controls Raspberry Pi Pico Door Lock

Building the smart home of your dreams is as easy as Pi—Raspberry Pi that is. To prove this, today’s project created by Jithin over at the Electromaker website is a Raspberry Pi Pico powered project that controls a door lock using Amazon Alexa’s voice control system.

The project works just as you might expect. It listens for the user to make an audible request and parses the voice command using Amazon’s Alexa servers which will trigger the door to lock or unlock based on what was said. This project requires internet access to work so Jithin used the first Wi-Fi enabled Pico, the $31 Arduino Nano RP2040 Connect board. That said, this project could easily be recreated using the new $6 Raspberry Pi Pico W at a much lower cost.
