Introduction: Google Assistant Controlled LED Matrix !

About: Hi, I'm Nemeen, Electronics Enthusiast! I have seen a huge decline in electronics hobbyist in past few years. I started this channel in order to inspire you to create. Hopefully, you will find something tha...

In this tutorial, I will show you how you can make Google Assistant Controlled LED Matrix which you can control form anywhere using a smartphone,

So let’s get started!

Step 1: Watch the Video !

If you don't want to read all the stuff you can watch my video!

Step 2: Everything We Need !

Step 3: Schematic, Code and Setup

Connect the

CLK to D5

CS to D8

DIN to D7 and

Vcc and GND pins to ESP8266 Board.

Then download the code for this project. Just enter your WiFi SSID and Password in the program and save it

Step 4: AdaFruit IO Setup

Head over to io.adafruit.com site

Once you login you will see Welcome Dashboard click on it, then click on Create New Block and select the Text then enter LED Matrix (program won’t work if you change it) and select Create then select it and click Next then Create Block. then go back to your dashboard and select View AIO Key and copy it.

Now open the program and paste this key here with username and upload this code to ESP8266 Board.

Step 5: Google Assistant Setup

Now we need to setup Google Assistant so we can control it to change the text on Matrix.

So head over to IFTTT.com,

Once you login select My Applets then New Applet, click on This and search Google Assistant and select it then click Connect select account and allow it

Then select Say a Phrase with Text Ingredient and here type "change matrix to $" so whenever you will say change matrix to and whatever will be after to(i.e in place of $ symbol), will be displayed.

You can select multiple triggers like that and also select what assistant will reply. Then select Create Trigger. Now click on That and search Adafruit click Connect and authorize it

Then select Send Data to Adafruit IO, select the feed name which we created earlier then click on Add Ingredient and select Text Field and hit Create Action.

That's it!

Step 6: Put Everything Together !

And last but now the least I designed case in Fusion 360 and 3D printed it on my 3D printer.

Print turned out to be great but I was not happy with the color so I decided to paint it. And because I am such a great artist I asked my friend to paint it you can follow her on Instagram

Then I gathered all the complementary component soldered it secured everything together with Hot Glue and this Project was Complete!
