Masina controlata prin bluetooth de pe telefon, se poate controla directia, viteza si tipul de avansare (automat sau controlat) care poate merge si in mod automat evitand obstacolele folosind un sezor ultrasonic.

Piese folosite:

• Placă Arduino Uno ATmega328P
• Placă de control motoare L293D
• Senzor ultrasonic HC-SR04
• Modul Bluetooth HC-05 master/slave
• Motor Servo SG90 9g 180 grade
• 4 x Motoare DC 3V-6V 1:120
• 4 x Roti
• Sasiu
• Suport baterii
• 2 x baterii 18650 (3.7V)
• Fire mama-tata, tata-tata

Descrierea codului aplicaţiei (firmware):

• mediu de dezvoltare: Arduino IDE
• librării şi surse 3rd-party:
  • AFMotor.h
  • NewPing.h
  • Servo.h
• cod
• Design:
  • Pentru controlul masini folosesc aplicatia de Android Bluetooth RC Car
  • Modulul de decodare a intructiunii trimise de aplicatie
  • Modulul de control automat
  • Modulul de citire a distantei
  • Modulul de alegere a directie
  • Modulurile de mers inainte si inapoi
  • Modulurile de virat la stanga si la dreapta

Am obtinut o masinuta care poate fi controlata prin telefon.
