Un cos de gunoi inteligent ce cuprinde un senzor care atunci cand ne apropiem cu resturile pe care dorim sa le reciclam/aruncam, clapa acestuia are un sistem cu un servo motor care va deschide automat clapa si ne va permite aruncarea acestuia.

• #include<Servo.h>

• Servo servo;
• int const trigPin1 = 5; senzor capac *int const echoPin1 = 4; *int const trigPin2 = 3; senzor capacitate
• int const echoPin2 = 2;
• int const greenpin = 8; led verde *int const redpin = 9; led rosu

• capacitatea
• pinMode(echoPin2, INPUT);
• pinMode(redpin, OUTPUT);
• pinMode(greenpin, OUTPUT);
• Serial.begin(9600);
• servo.attach(6);

• digitalWrite(trigPin1, HIGH);

Pot spune ca a fost o experienta placuta, dar si provocatoare in acelasi timp, un proiect fascinant care m-a ajutat sa inteleg mai bine materia.
