Dear Guys,I am now doing my university project.This project name is called wireless remote control Car.I want to use some funtionality for my car design.
1.Bluetooth control for driving car(Forward,Backward,Turn left ,Turn right,Release)
2.Avoiding obstacle using Ultrasonic sensor
3.Horn and signal with LEDs
For above describe functionalities ,I use the following materials.The list are in below.
1.Arduino UNO board
2.L293D DC motor control drive Shield
3.Bluetooth module(HC-06)
4.Ultrasonic sensor (HC-SR04)
5.Two DC motor
6.Speaker(8 ohm )and LEDs
Firstly we are using only without motor shiled and
control code over bluetooth.It is very nice for simple DC motor and it is very ok.I am happy.But,When I attached with car motor ,it does not work ,It is because of load (can`t support required current).For bluetooth module,I already use RX and TX . to control motor forward and backward.Turn left and right.So,I must decide to find new design.I found motor shield.
Secondly,I use L293D motor shield for motor control.It is only convenient for serial data in (I mean signal control only using serial motor tool default built in Arduino IDE). When I have idea to connect with bluetooth module),actually it does not work and does not reach singals.I combine using arduino and motor shiled,I have a little difficulties for connecting wires (ie.
digital pins ,analog pins,etc from arduino board).
According to my desire,I want to control my car driving using bluetooth over mobile phone(BlueStick ).But the bluetooth singal does not work when I am connecting with motor shiled.my Car design is four wheels using two DC motors.The first motor is using forward and backward.I found the code how to spin motor forward and backward.Another one is Turn left and right using the same function like as forward and backward ;it is ok.
Please sir,Another desirable condition is avoiding obstacle using Ultranosic Distance sensor.When sensor detect in the desire distance,turn left or right.
Hopefully,:you can help me my project.Please help me sir.My project due date is so near and near.Help me.
