A Simple Proteus project for Beginners

Obstacle Avoiding Circuit : 

We have to draw an obstacle avoiding circuit in proteus. For that, open proteus and select the following components . If you don't have proteus , then you can download and install it from here .

1.              Arduino UNO R3

2.               LOGICSTATE (I have used this instead of  “Echo” pin of the ultrasonic                                                                 sensor)

3.               2 DC Motors

4.                Motor Driver (L293D)

5.               Ground

6.               5 Volt Power supply

th

                                  fig : - Schematic diagram for the circuit              

sc                        

Connection :

1.                LOGICSTATE to PIN 2

2.                Left Motor to OUT 1 & OUT 2

3.                Right Motor to OUT 3 & OUT 4

4.                 IN1 to PIN 3 & IN2 to PIN 4

5.                 IN3 to PIN 5 & IN4 to PIN 6

6.                VSS,VS,EN 1 & EN 2 to 5 V power suplly

Test :

Also, you can test the circuit ,if it’s working properly. For that, write an Arduino code for obstacle avoiding .

void setup() {

              pinMode(2, INPUT);

              pinMode(3, OUTPUT);

              pinMode(4, OUTPUT);

              pinMode(5, OUTPUT);

              pinMode(6, OUTPUT);

                    }

void general(){

              digitalWrite(3,HIGH);

              digitalWrite(4,LOW);

              digitalWrite(5,HIGH);

              digitalWrite(6,LOW);

                     }

void stop(){

              digitalWrite(3,HIGH);

              digitalWrite(4,HIGH);

              digitalWrite(5,HIGH);

              digitalWrite(6,HIGH);

                 }

void loop(){          

              if(digitalRead(2)==HIGH){

                    stop();

                                              }

              else{

                    general();

                     }

                }

Now

1.  Compile the code.

2.  Select the .hex file location of the code from the bottom of the compiling page.

3.  Open the Proteus , double left click on Arduino board.

4. Paste the file on the marked space.

5. Run the simulation .

Observation:

On pressing the Logic State to HIGH the motors will stop , this means the detection of obstacle and on the LOW state the motors will run , that means there are no obstacles.

It is a small project for beginners . You can try it , it will be fun.
