TASK 1 : Basic Drawings On Paper

Description :

Aim :

to familiarize with the Shapes and put them on Paper - Observe the given 3D design carefully (especially the dimensions and basic geometric shapes). - Once the observation is done, visualise differentiating the 3D design into top view , front view, side view. - Now using the required tools (pencil, mini drafter, compass etc...) manually draft the 3D design to the orthographic view (2D view).

TASK 2 : LED On a Breadboard

Description :

Aim :

to understand the Basics of LED Brief description of tasks : Here I performed two types of LED connections. - Series connection - Parallel connection Components required are a breadboard, wire links, breadboard power supply. - A LED is plugged in with the required resistor and when it is turned on the LED glows. - for a single LED, i have used 1k ohm resistor in series with the LED. - here i've tried lighting up LED sequences using AA batteries. - For multiple led in series, Since i have used 9V battery the maximum LEDs that i could connect is 3 with 500 ohm resistor connected in series - Two LEDs are plugged in a series connection with the required resistor and when it is turned on both the LEDs glow. - Two LEDs are plugged in a parallel connection with the required resistor and when it is turned on both the LEDs glow. - I tried 3 LEDs in parallel with 500 ohms of resistance,

• single LED only draws around 20mA of current Ideally. Note : - Most of the LED usually draws around 15 to 20mA of current to operate - A 9V battery can supply maximum of 2A of current

TASK 3 : Transistor as A Switch

Description :

Aim :

to operate a transistor as a switch by biasing it appropriately - Plug Transistor to the breadboard. - Connect emitter to the ground of the battery. - Connect LED to the collector of the transistor. - Connect 330 Ohm Resistor to the collector of the transistor. - Connect 1k resistor to the base of the transistor - Connect Switch to the base of the transistor. - Power up the circuit with 9V Battery. - The LEDs will glow when the switch is pressed.

TASK 5 : Darkness Detector using LDR

Description :

Aim :

to create a circuit that turns on an LED when the room is dark - Plug a npn transistor to the breadboard. - Connect the base of the transistor to the LDR. - Connect another end of the LDR to the positive terminal. - Connect the emitter of the transistor to the ground. - Connect one end of the 1k resistor to the base of the transistor and the other end to the ground. - Connect the negative end of the LED to the collector of the transistor and connect the 470ohm resistor to the positive end of the LED and the other end of the resistor is connected to the positive terminal of the battery. - As the brightness increases light glows brighter.

TASK 6 :

Convert Your Drawings On paper to CAD

Description :

Aim :

to replicate the given drawings using CAD tools - i've used Catia V5 software was used to design the prototype as shown in the picture below. - The 2D of the prototype was built in this software using the required tools. - Now the 2d design was padded to the 3d prototype. - Finally the required changes (like pocketin ille olour change etc...) were done to get the required prototype.
