void setup()

{

pinMode(30,OUTPUT); pinMode(31,OUTPUT);

pinMode(8,INPUT); Serial.begin(9600);

}

void loop()

{

digitalWrite(m1,HIGH); digitalWrite(m2,HIGH);

if(digitalRead(ir)!=1) { delay(1000); digitalWrite(m1,HIGH); digitalWrite(m2,LOW); delay(500); digitalWrite(m1,HIGH); digitalWrite(m2,HIGH); delay(500); digitalWrite(m1,HIGH); digitalWrite(m2,LOW); delay(1000)

}

WORKING:

1. This mechanism is for the intake of the paper (cut in pre-set dimensions)
2. The IR Sensor detects the paper and the roller starts rotating in the direction to pull the paper in
3. The roller stops after the paper has reached its appropriate position

Functionality test report:

Report

The rollers were made using PVC pipes of dimensions according to the need. For increasing the thickness if the PVC pipes double tape was used. Rubber bands were used to maintain friction between the paper and the roller.

COMPONENTS:

1. PVC pipe (Acts as the roller)
2. PVC caps (to keeps the pipe in perfect position)
3. Aluminium pipe (To attach the DC motor with the pipe)
4. 60 RPM DC motor (used to rotate the rollers)

Integration test results:

The intake system is synchronized with the system.
