Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLK Day, shipping could be delayed. Please allow extra time for your order to ship!
Decided I needed a quick and easy way to find and store my things using a voice assistant. I also wanted control over my data locally and not rely on the cloud. So I kept the data base locally in a csv file on my raspberry pi. This gives it a added benefit as I can access the csv at any time and do more advance queries later. I choose Alexa because it is something I have not worked with before and wanted to see how it works compare to google. I also used a pi zero because I wanted to use something cheap which will control the LED and not dedicate a pi 3.
The flow is relatively simple. You ask Alexa with a special skill word called “invocation” such as “storage room”. Then the Alexa skill will take your query and send it off to Amazon’s Lambda application. This is where your query is parsed and the code here will determine the task to perform. In this case it will take your query as is and send it off to AWS IOT Thing. The IOT-Thing is external accessible point in the cloud where raspberry pi with the proper credentials can access and subscribe for interactions. The IOT-Thing will update it’s flags to indicate a change has been made. The python script on the pi will see that there has been a change and will initiate a download of the data. The data contains your query to Alexa. The python script on the pi will then parse out what you are asking for and determines an action. If you were looking for something and there was match then a LED will light up where your item is.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
