Arduino:How to use motor driver module L293D

       Motor Driver L293D module 




This motor driver module has 4 input pins which will be connected to the arduino and 4 output pins which will be connected with the two motors,and there are 3 more pins which is 12v input ,5v input and a GND(negative terminal)
the module can be powered by 12v supply or a 5v supply.and it can control  2 motors

CODE to upload


int motorpin1=5;
int motorpin2=6;
int motorpin3=7;
int motorpin4=8;

void setup()
{
pinMode(motorpin1,OUTPUT);
pinMode(motorpin2,OUTPUT);
pinMode(motorpin3,OUTPUT);
pinMode(motorpin4,OUTPUT);

}
void loop()
{

digitalWrite(motorpin1,HIGH);
digitalWrite(motorpin2,LOW);
digitalWrite(motorpin3,HIGH);
digitalWrite(motorpin4,LOW);

}




After uploading the code ,the motors will start spinning in CLOCKWISE direction,this is because of the HIGH ,LOW sequence written in the code
You can also change the direction of spinning of the motor by just changing the the code sequence as follows-:
For clockwise spin:-

digitalWrite(motorpin1,HIGH);
digitalWrite(motorpin2,LOW);
digitalWrite(motorpin3,HIGH);
digitalWrite(motorpin4,LOW);
For Anticlockwise spin:-

digitalWrite(motorpin1,LOW);
digitalWrite(motorpin2,HIGH);
digitalWrite(motorpin3,LOW);
digitalWrite(motorpin4,HIGH);

Here,
HIGH 
LOW ,corresponds to clock spin

where as 
LOW
HIGH ,correspond to clock spin

Just change the sequences as according to your project working and you will get the desired results!!

Thanks for reading ,hope you are done with the motor driver project
If still there is a problem in spinning or any thing else just write in the comment box.

Arduino:How to program an arduino using loop statements

Image
Programming  an Arduino(Level 2) using loop statements   1.Conditional statements(if/else) These statements are executed when the condition which is specified in it becomes true And these statement's are used when when we need to perform a specific task after the condition becomes true ,we can write this statement if the void loop field like this if(condition) { (Task which need to be performed goes here) } else { (If the condition becomes false then this block of code will be executed) } Example of code if ( x > 120 ) digitalWrite (LEDpin, HIGH ); if (x > 120 ) digitalWrite (LEDpin, HIGH ); if (x > 120 ){ digitalWrite (LEDpin, HIGH ); } if (x > 120 ){ digitalWrite (LEDpin1, HIGH ); digitalWrite (LEDpin2, HIGH ); } 2.While loop(while) A  while  loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something must change the tested varia

Automatic Door Locking with Arduino

Automatic Door Locking and Unlocking System With Arduino. Components Required:- 1.Arduino MEGA 2.Keypad 4*4 3.Infrared Module (*2) 4.LCD Display 16*2 5.Power Supply(it can be between 5v to 12v max) (I have used 12v adapter for arduino and a 5v adapter for servo motor) 6.breadboard(optional) 7.box for Fitting the lcd and keypad 8.jumper wires **(I have used an external power supply for servo motor because, a rduino is not capable for supplying large current greater the 600mA and their are two many thing attached to arduino here which is continuously taking current through it, so it may happen that servo motor stop working due reduction in current) **(This has happened with me,the arduino keep on going reboot again and again)  Working of the lock:- Password for this is 1234. First if the door is closed and we enter the password 1234,it will print "Access Granted" on LCD and the door will open using the servo motor,I have

Arduino:How to make a RC car with arduino

Image
MULTI FEATURED ROBOT WITH ARDUINO This robot was mainly built for understanding Arduino and combining various projects of Arduino to form a Multi Featured Arduino Robot. And further, who doesn't want to have a pet robot? So I named it BLUE ROVIER 316. I could have bought a beautiful tracked chassis but making it from scratch teaches you more and gives you more pride after you have completed it. The robot is capable of understanding voice commands, answering simple questions, controlling as an RC car and even avoiding obstacles while moving. It is mainly controlled through an Android phone which is connected to it through Bluetooth. Based on Android features such as Google Voice Recognition and Tilt sensing, it can really behave like a cute, smart robot. I added BLUE in its name because it is mainly based on Bluetooth. It was actually my first Arduino project and I wanted it to be unique . If you like the project, please do vote for me in the Robotics Contest ! You w
