As per programming code, we have created 5 LED strip for arduino digital pin mode terminals on PCB.  (Terminals pin mode 2, 3, 4, 5, & 6) and one ground (- ve)



Above terminals connected to arduino board. And we have provided power supply to arduino board through the 9 volt battery.

After the finished connectivity, we have fitted arduino board, LED strip and 9 volt battery. Program code compiled successfully.  












FABLAB- Engraving : Reflective image

I have downloaded mesh image over internet and edited coral draw and created a beautiful animal. The image engraved and cut on laser cutter.  For this image we have created 5 LED strip in parallel connection. We used white led, but blue led will be better for reflection image.
I have made proper box on box maker software (online software) for image fitting.

FABLAB - LANTERN MAKING

1. I have made lantern for diwali occasion using following software.

1    Inkscape and box maker – download the proper box from internet software of box maker design. The box imported in inkscape and draws the stars in box. Cut it on laser cutter.



12. Autodesk 123D Make -Suhas sir gave an idea to using about Autodesk 123D Make software for lantern. It software makes slices in 2D designs.  But first of all we have to create 3D design in 123D design software and after then import design in 123d make (Export as 3D .stl format). This is very useful software for us. It makes slices and creates proper slots for assembled, so we can assemble object easily. (it convert from 123D to 2D design)






3. We have used LDR circuit and LED for this lantern.

Name
:
Sandeep Jagannath More
Section
:
Electrical and FABLAB
Project Name
:
Fab Switch (Display the bulb on motion (PIR) Sensor
Target /Object
:
If we go to the dream house bulb will automatically switch on for 10 seconds.
Assembled Location
:
At Dream House, Vidnyan Ashram Pabal.
Guidance
:
Suyog sir and Suhas sir 








Planning: Identified the need of this motion sensor (which is sensing motions), location and find out the benefits of this project.

Benefits: 
1.  Electricity Saving
2. Different and more uses of PIR sensor (f.g. we can use for thief protection etc.)


Achievement/Experience: First of all I have learned and understood the project from Mr. Suhas sir, who is the Fablab In-charge. Then same I have explained this project to workshop and electrical students. So My confidence has increased, understood the connectivity of Ardiuno board (Input-Output), relay circuit and more uses of motion PIR sensor and Ardiuno board.

Testing programming code

We have taken trial of PIR on ardunio board and LED bulb with programming code. I have found the particular programming code (arduino) in software but I did not get the particular code. Then I find out two codes over the internet and four to five times took trial & errors. Following code matched the project.

Code

const int ledPin= 13;
const int inputPin= 7;
void setup(){
pinMode(ledPin, OUTPUT);
pinMode(inputPin, INPUT);
pinMode(5,OUTPUT);
digitalWrite(5,HIGH);
}
void loop(){
int value= digitalRead(inputPin);
if (value == HIGH)
{
digitalWrite(ledPin, HIGH);
delay(10000);
}
else
{
digitalWrite(ledPin, LOW);
}
}

This code tested on arduino board with LED and PIR sensor. Program complied successfully. 


Relay Driving Circuit connectivity.

For this project we need a Relay Driving Circuit. This circuit is working for switching.
I have understood the relay driving circuit and its connections (VCC, GRND, IN1, IN2 & COM GRND, and GRND). But its need to 12 volt power supply. So we have provided power supply through the 12 volt adapter (mobile charger it convert to DC current from AC). We have used also 7805 voltage regulator for this connection. From this connection we could provide 12 volt power supply for Relay circuit and 5 volt ardiuno board.   


Connectivity- Motion Sensor, Ardinuo board & Relay circuit.

We have connected and provided proper connection for motion sensor to ardiuno board and Relay circuit to ardiuno board with jumper wires. We have defined 5 number pin modes in programming code for PIR power supply.


Used of Laser cutter machine and box maker/design software 

For assemble, we have made box on ‘online box designer software’. This is very useful software for making box. In this software we should mention dimensions /sizes of box (Length x breadth x height) and we should click on the design it, then automatically box will create in PDF file format. We can do many changes and additions in this box. But for these changes we have to Inkscape software (it is free online software). As per our box design we created box for fab switch. We have assembled the project.


Fab Switch assembled successfully in proper box.

After the final connections of all components, we have assembled all components in box.  Also we have connected connector (output) for bulb. (From relay to bulb connection)


Fab switch implemented successfully at Dream House with the help of Electrical and Workshop Students.


A lot of thanks to Mr. Suhas sir who guided and helped me to make this project.


I have explained purpose of this project to DBRT Principal Mr. Vishal Jagtap sir and Workshop Teacher Vishwas Shinde sir. 


Faced problems while making this project:

1.     Firstly I could not find out the motion sensor wires of plus, mines and ground. Then I have received diagram on internet and connected properly.
2.     Because of the loosed connection of voltage regulator, the regulator has damaged. So replaced the regulator.
3.     We were facing the proper soldering.

Observations:

1.     I can use ardiuno board, motion sensor (PIR) and relay circuit properly.
2.     A lot of uses of ardiuno board.
3.     My confidence has increased.
4.     I can do different activity with ardiuno board.

     Thanks.
