Electronic, Craft, 3-D Ganesha Material: 2-D design print of Ganesha, Water color ,  Glue, 3-D Printed foundation stand, Sketch pens. Electronic material:  Arduino kit, Jumper wire, PCB, Battery 5 V, Connector, Breadboard, RGB LEDs Tools: Soldering Gun, Scissor Lesson plan: 1. Make a 2-D print of Ganapati on bond paper. 2. Cut the design using scissors. 3. Join the Ganapati body parts as shown in sequence. 4. Paint each part of the body using colors, sketch pen or water color, color should be simple and sober. 5. Attached chakra behind the Ganapati head.. 6. Now placed the Ganpati on the foundation. 7. Write a code for Arduino with ultrasonic sensor. 8.  Connect ultrasonic sensor with Microcontroller and do numbers of practicals, write code in such way that you will get lights on when you will be come in between 30 cm range from the system. 10. Mount the RGB lights on the PCB and soldering it properly. 9. Now attached your electronic system with the Ganapati foundation an...

3-D Ganpati Material / Filament :  PLA Temperature:      Bed Temperature - 70 degree celsius      Nozzle Temperature - 220 degree celsius Working   : 1. First we have to calibrate the axis. 2. We have to see that between the extrude and the bed, there should be a gap of A 4 size of a paper and should be removed by medium strength. Before the model has printed, the bed should be glued up by glue stick. 3. Using USB device we have to give print. 4. After gave the print, we have to check temperature of nozzle 220* and 60* of bed. If it is not automatically raising then we have to  manually give temperature. 5. Then the system will work automatically, as per your design size the printing job will be taking time. Result:  If we do these things correctly, the model becomes neat and tidy. So the model may be a skeleton, a tree, etc. Created By: Soham Abhyankar (5th)

A simple multiplayer game using Scratch by MIT Software: Scratch by MIT Code for each character: Working : The first player uses arrow keys to move the character, and the second player uses w and d keys. If the character touches the black color, then the character has to start again   from the start. If   he reaches the green portion, he wins!   Photos:   Videos:     Result:   A simple multiplayer game was made using Scratch software. Simple block coding was done by Soham and Shreyas. As of beginning, a single player game was created and then second character was added to make the game more interesting and competitive.

Digital Rakhi Workshop Component: LED, Black paper, White paper, Connecting wire, 3 Volt cell, Switch button, Steel plate, Decorating material, PCB. Working: When we turn on the switch, 5 LED lights will turn on. These are turned on by a cell inside the bottle cap (on which they are on) and they will reflect on the steel frame, which creating a beautiful effect.   Result:  Done By: Samadnya Bidve (8th Standard)

  Digital Rakhi  Components:- LED, White Paper, Connecting Wire, 3 volt cell, Switch Button, Decorative Material. Working:- When we on the switch, the lights will be displayed. The light will reflect on the paper and will bright up the name. Photo / Video:- Result: Created By:   Gargee Dixit  (7th std)

Cat maze game: Software : Scratch S4A 1.6 Coding : Working: If we click up arrow key, the cat goes upwards. If we click down arrow key, then the cat goes down. If we click left arrow key, the cat goes left. If we click right arrow key, the cat goes right . Output: Result: We control the cat by the arrow keys .If the cat touches the blue color, the cat goes to the yellow patch, that is,start.If it reaches to the end of the maze, the cat wins.

  Component: 1-  Arduino 2- Sound Sensor 3- Led light 4- Resistor - 1k ohm Circuit Diagram: Working : आपण बोललो कि साऊंड सेन्सर ते सेन्स करतं, मग तो सिग्नल Arduino ला आणि मग Arduino तो सिग्नल वोल्टच्या स्वरूपात led ला पाठवतो आणि दिवा चमकतो. समजा आपण मोठया आवाजात बोललो तर दिवा जास्त प्रखरपणे चमकेल. Result:  More the frequency of voice the time led will glow. Created By: Sahil
