Basic Sensors Used in Robotics

                In my previous post Getting Started with Robotics we have seen a brief introduction about basic sensors used in the field of Robotics. In this post I am going to write How to use these sensors i.e., application of these sensors in the field of Robotics with circuit diagram and programming code of Arduino Microcontroller.In this post I will show you how to use and program Temperature sensor and Photoresistor

            Before entering into the project's, let us have a look at the Arduino UNO board. The Arduino UNO Microcontroller is based on ATmega328. It has 14 digital input/output pins numbered from 0 to 13. In these 14 pins we have 6 PWM pins (Pulse Width Modulation outputs). Arduino uno has 6 analog input pins numbered from A0 to A5. The analog pins maps the input voltage between 0 and 5 Volts into integer values between 0 and 1023. You can learn more about Arduino in the official Arduino website http://www.arduino.cc.
