Robot de urm\u0103rire linie folosind Arduino \u0219i modulul L298N<\/span>
\nLine Follower Robot Using Arduino And L298N Module<\/span><\/h4>\n

Robotul de urm\u0103rire a liniilor este un vehicul automat care urmeaz\u0103 o linie vizual\u0103 neagr\u0103 sau o cale pe o suprafa\u021b\u0103.
\nFolose\u0219te o linie neagr\u0103 pe o suprafa\u021b\u0103 alb\u0103 sau o linie alb\u0103 pe o suprafa\u021b\u0103 neagr\u0103.
\nVom \u00eenv\u0103\u021ba cum s\u0103 facem un robot de urm\u0103rire a liniilor folosind Arduino \u0219i modulul de driver de motor L298N.<\/p>\n

CUM FUNC\u021aIONEAZ\u0102 ROBOTUL „LINE FOLLOWER” ?<\/strong><\/p>\n

Conceptul de robot de urm\u0103rire a liniilor este legat de transmiterea \u0219i recep\u021bia luminii. Culoarea alb\u0103 reflect\u0103 toat\u0103 lumina care cade pe ea, \u00een timp ce culoarea neagr\u0103 absoarbe toat\u0103 lumina.
\n\u00cen acest robot de urm\u0103rire a liniilor, am folosit transmi\u021b\u0103toare \u0219i receptoare IR.
\nC\u00e2nd lumina IR cade pe o suprafa\u021b\u0103 alb\u0103, este reflectat\u0103 \u00eenapoi c\u0103tre receptorul IR, gener\u00e2nd unele modific\u0103ri de tensiune care sunt analizate de Arduino.
\nC\u00e2nd lumina IR cade pe o suprafa\u021b\u0103 neagr\u0103, este absorbit\u0103 de suprafa\u021ba neagr\u0103 \u0219i nicio raz\u0103 nu este reflectat\u0103 \u00eenapoi, astfel \u00eenc\u00e2t receptorul IR nu prime\u0219te nicio raz\u0103.
\n\u00cen acest proiect, c\u00e2nd senzorul IR detecteaz\u0103 o suprafa\u021b\u0103 alb\u0103, starea de intrare Arduino devine HIGH, iar c\u00e2nd detecteaz\u0103 o linie neagr\u0103, devine LOW.
\nPe baza acestor intr\u0103ri, un Arduino Uno ofer\u0103 ie\u0219irea adecvat\u0103 pentru a controla urm\u0103ritorul de linie.<\/p>\n

SCHEMA CIRCUIT ROBOT LINIE FOLLER<\/strong>

\"Line-Follower-Circuit-Diagram\"<\/a><\/p>\n

Urma\u021bi acest tabel pentru a v\u0103 face conexiunile.<\/strong><\/p>\n

L298N driver Pins –> Arduino Pins
\nENA –> jumper
\nIN1 –> D9
\nIN2 –> D6
\nIN3 –> D5
\nIN4 –> D3
\nENB –> jumper<\/p>\n

Infrared Sensor pins –> Arduino pins
\nVcc –> 5v
\nGND –> GND
\nRight IR sensor OUT –> D13
\nLeft IR sensor OUT –> D12<\/p>\n

Pentru modulul de driver de motor L298N, motoarele sunt conectate la bornele de motor ale modulului de driver de motor.
\nDriverul motorului are alte 3 borne, \u00een care unul este de 12 vol\u021bi conectat la baterie.
\nTerminalul GND este conectat la borna negativ\u0103 a bateriei \u0219i, de asemenea, este conectat la pinul GND al pl\u0103cii Arduino
\nSi 5v este conectat la 5v a pl\u0103cii Arduino.<\/p>\n
