About the project
AKNO is a smart, kind, and cute robot made with love and wires.
By Moksh Gupta
Akno is a smart robot with voice recognition and facial expressions. It reacts with voice commands with 25 voice command and it has 15 different facial expression on 128*64 lcd display via SPI, and the main AKNO'S brain is the Arduino MEGA 2560 Powered by two 18650 3.7v 2000mAh batteries. With two common Anode RGB LEDs one in the front and one in the back of the robot, with 3 push buttons for a varies functionalities. /**/
===========================================
/Features/ Akno support's more than 250 voice command (25 of them is already in use at that version)
15 different facial expression with smoth animation (happy, sad, angry, upset, normal, cute, suspicious, iam, youmademe, wonder, downeye, righteye, lefteye, upeye, blink) plus two RGB LEDs effects.
6 different moving pattern (right, left, forward, backward, spinning, doproblems)
Akno support's game mode (PongGame) you can play with him.
You can add more features if you're familiar with c/c++. /**/
===========================================
/* NOTICE CAREFULLY*/ Please notice all buttons connected to analog pin with resistors, so you should consider that if you want to change the buttons into digital pin.
All enable pins of the motor driver which (l293d) ic at high state, or you can just attach it to 5v.
I used common Anode RGB LEDs at this version of AKNO, so if you want to use common Cathode LEDs you should make changes at : expressions.h/(line:250&line:262)/(LED1&LED2) functions by Just deactivate the marked three lines. /**/
===========================================
This is the the worst code I've ever written, but it works :)

Cloud computing refers to the delivery of on-demand computing resources over the internet. It allows individuals and businesses to access and utilize a wide range of services, including storage, servers, databases, software, and applications, without the need for on-premises infrastructure. Cloud computing provides flexibility, scalability, and cost-efficiency, enabling users to scale their resources up or down based on their needs and pay only for what they use. With cloud computing, data and applications are stored and processed in remote data centers, providing seamless access from any location with an internet connection. It has revolutionized the way organizations manage and deploy their IT resources, empowering innovation and digital transformation across various industries.
