                      Arduino Self-Driving Car



Hardware Components:


  1. 1x Car Chassis Kit: 
    • 2x Gear Motor
    • 1x Car Chassis
    • 2x Car Tire
    • 1x 360° Wheel
  2. 1x Arduino Nano
  3. 1x Mini Breadboard
  4. 1x Motor Drive L293D
  5. 3x Ultrasonic Sensor HC SR04
  6. 3x Sensor support - 3D printed (see drawing below)
  7. 1x 9v Battery
  8. 1x On-off switch
  9. 5x 100uF capacitors
  10. 2x 0.1uF capacitors
  11. 1x IR Receiver
  12. 1x Remote Control



Software Components:


1. Arduino IDE

2. Google Maps/Maria API

3. Mobile App (LED App Admin Side)


System Workflow:


Automatic Driving Mode:


1. Get current location of car through GPS module.

2. Send location data to phone via GSM/Cellular module.

3. Phone connects to Google Maps/Maria API to get route.

4. API sends route instructions to Arduino.

5. Arduino processes instructions (forward, left, right).

6. Send instructions to motor control unit.

7. Repeat steps 5-6 until next instruction.

8. End navigation when destination is reached.


LED App Admin Side:


Screen 1: Destination Entry


1. Drop-down search using API.

2. Enter destination address.

3. Map view with route preview.


Screen 2: Real-time Navigation


1. Map updates real-time location of car.

2. Start navigation and bring car to destination.

3. Continue to next navigation route.


API Integration:


1. Google Maps/Maria API for routing and navigation.

2. API for drop-down search (e.g., Google Places API).


Technical Requirements:


1. GPS and GSM/Cellular module integration.

2. API integration with Arduino.

3. Mobile app development (LED App Admin Side).

4. Motor control unit programming.

5. Sensor integration (e.g., ultrasonic, lidar). 

Assembling the chassis :

  • Assemble the chassis 
  • The breadboard can be fixated at the back of the chassis.
  • It is important that the battery is placed on the front part of the chassis due to its weight.
  • Screw or glue the sensor supports on the front of the chassis
  • The sensor can be placed with pressure on its supports. It's not necessary to glue or screw it.
  • Wiring :

 It is in metal, with its roots in raw energy, aggression, and sometimes intricate musical forms, that a niche has been hewn out of the world of music. Changes in popular culture and society and relentless creativity forge a hand-in-hand relationship with the past, present, and future course of heavy metal. A Heavy Metal Revolution: The Birth of Metal It has its roots in the late 1960s and early 1970s bands that began to experiment with heavier sounds and darker themes, extended guitar solos. They had a massive impact, forming the basis of the many subgenres to come. Black Sabbath: Pioneers of doom metal with dark, despairing, and occult themes. Led Zeppelin: A fusion of blues, rock, and folk, featuring strong riffs and soaring vocals with intricate arrangement.                                                                ...
