The fabrication of the subsystem involves the usage of one servo motor, 3 mm acrylic sheet. The acrylic sheet is cut using laser cutter.

#include<Servo.h> Servo S1,S2,S3,S4; int servoPos=0;

void setup() { // put your setup code here, to run once:

S1.attach(6); Serial.begin(9600); }

void loop() { // put your main code here, to run repeatedly: for(servoPos=0; servoPos<40; servoPos++) { S1.write(servoPos); delay(20); } for(servoPos=40; servoPos>0; servoPos--) { S1.write(servoPos);

delay(20);

}
