SENSOR TUTORIAL

Image
TYPES OF SENSORS USED IN ROBOTICS  1. IR Sensor  An IR sensor is an electronic device that detects infrared radiation to sense objects or measure temperature. It works by either emitting infrared light and detecting the reflection off an object, or by directly sensing the thermal radiation from an object. Common applications include remote controls, security systems, motion detectors, and automated lighting.   2. Flame Sensor  A flame sensor detects the presence of fire by sensing electromagnetic radiation, typically infrared (IR) or ultraviolet (UV) light emitted by flames. These sensors are faster and more accurate than smoke detectors and are used in safety systems to trigger alarms, activate suppression systems, or shut down equipment. Popular types include infrared sensors that look for specific infrared wavelengths and UV sensors that detect UV rays, with common implementations featuring adjustable sensitivity and both digital and analog outputs.  3. ...

ARDUINO TUTORIAL

Image
ARDUINO TUTORIAL  DESCRIPTION :- Arduino is an open-source microcontroller platform designed to make electronics and programming simple and accessible for everyone — from beginners to professionals. It consists of both hardware (Arduino boards like Uno, Nano, Mega) and software (Arduino IDE) that lets users write and upload code to the board. Using sensors, motors, LEDs, and other electronic components, Arduino can be used to build a wide range of projects — such as robots, automation systems, IoT devices, and prototypes. Its simplicity, large community support, and open-source nature make Arduino one of the most popular tools for learning electronics and coding. BASICS ARDUINO TYPES:- Arduino Uno  The Arduino Uno is an open-source microcontroller board based on the ATmega328P chip, popular for electronics projects and learning. It features 14 digital input/output pins (6 of which can be used for PWM) and 6 analog input pins, and it can be programmed using the free Arduino IDE...
