So I am a newbie in arduino project-making and I just made my second robot (the first one is a ultrasonic sensor object avoider) that self-balances. Anyway, I just found some 2$ sunglasses that look cool and I wanted to make smart glasses, using the HC-05, arduino nano or pro mini, a microphone and a speaker (since the speaker is so close to my ears they don't need an amplifier). The ideea is that the glasses are thick ( T H I C C ) and they can fit the components. Okay, back to the projects: I want to make a program that comunicates with my phone and I want to ask questions using the google assistant (Ok google).
I have no experience in c++ programming so if you are going to help me, please provide a code. Can someone create such a program or at least link me to a project?
Thanks in advance

Basic communication with your phone (over Bluetooth) will work. But microphone, voice recordings and transmissions... that's not exactly Arduino's forte. You're going to need very different hardware for that. You may start with an Android phone that you can build into your device after removing all unnecessary bits.

So, you want a bluetooth hands-free headset and a pair of sunglasses.
Yes... that was my thought, too. Ready made hands-free set that communicates directly to your phone, attached to the sunglasses.
Not an Arduino project; hardly worthy a DIY project even.
