3.  Simulating the operation of a car in traffic
 Improving an electric car
 Car control by 2 methods :
◦ a) manual : the car is control by a human user
◦ b) autonomous : the car is controlled by microcontroller

6. For I have combined the knowledge gained regarding :
 DC motor control
 Microcontroller’s programming
 Serial communication
 Object oriented programming

8.  Writing a C++ code for
the Arduino
microcontroller
 Developing an Android
app
It is structured on 2 components :

9. The app is the main tool used to send
instructions from smartphone to the
microcontroller
App’s functions :
 Bluetooth device scanning
 Pairing with bluetooth devices
 Mode selection :Manual/Autonom

11.  The microcontroller receives ASCII values from the smartphone via
Bluetooth and according with the received code will call the
appropriate function from the microcontroller’s code.
 The ASCII values used :
 ‘a’ - forward
 ‘b’ - back
 ‘c’ – brake
 ‘4’ - right
 ‘5’ - left
 ‘7’ – hazards
 ‘8’ – buzzer
 ‘9’ – automatic mode
 ‘d’ – deactivate automatic mode

12. The ASCII values received
Distances measured by
the sensores

16. In this project were achieved the following :
 DC motor control
 Distance measurement using ultrasonic sensors
 An app to send the instructions
 A C++ code for microcontroller which executes the
instructions received from the smartphone
