ECE COMPONENT u The Arduino Processor, Robots and Gadgets

A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. The Arduino Uno is a microcontroller board based on the ATmega328. The Arduino Uno is a special micro controller which has all of its I/O pins mapped out for connecting various kind out of sensors and other I/O pheraphial devices. This I/O pins can be controlled directly by providing programming instruction in the Arduino IDE called a sketch.

All the sensors are connected to the digital I/O pins of the Arduino Uno Microcontroller. Once the Hardware is connected (the sensors and the motors) to the board, the software is written on the Arduino IDE in a file called Sketch. The sketch are similar to C++ programming language, but are linked to various precompiled functions that takes care of lot of behind the scene hardware programming involved. Once the desired Sketch is written, the Sketch is uploaded to the flash memory of the Arduino Uno’s flash memory via a USB cable.

The Arduino Uno based robot is based on the concept of digital feedback control network. A feedback control network takes in information from the sensors and goes through a algorithmic decision making process, that drives the Robot. In this case we use a ping ultrasonic sensor that makes a measurement of distance to the left, right and in front of the robot. After making the measurements, the microprocessor compares all the values and makes a decision of going in the direction of the maximum distance.
