COMMOM TASK FINAL REPORT- NAVYA\n\n- - - -\n# TASK 2: API\n- - -\n## What is an API?\n API stands for Application Programming Interface. In the context of APIs, the word Application refers to any software with a distinct function. Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses.\n## Here is a Real Time Weather App using Open Weather API\n- - - \n## Steps of operation:\n1. We make use of the jQuery Plugin for displaying RealTime Weather data: https://github.com/michael-lynch/open-weather\n2. Download and extract all the contents of the folder.\n3. Paste the contents into VSCode and run. code in the cmd prompt.\n4. Open the folder named demo -> index.html\n5. Right-click and open with Live Server\n6. Create a free account in openweathermap.org\n7. Go to API Key and copy the given API key and paste it in the openWeather function.\n8. Make the API more dynamic by pasting the contents in a new function and make it accept the input from the user for name of the city, instead of the default.\n- - - \n ## Working Image of Weather API:\n\n# TASK 3.Working with GitHub\n- - - -\nThe main branch of this repository has an error and is failing tests.

Plug the esp32 into the computer and follow the instructions on the given resource article (stated above).\n\n\n# TASK 12 : Soldering Prerequisites\n- - - - - -\n## Soldering Equipment:\n1. Soldering Iron: This handheld tool provides the heat source needed to melt the solder. Soldering irons are typically pencil-like in shape and consist of several different parts that work together to form a comfortable, practical and easy-to-use tool.\n\n2. Solder Flux: Solder flux is a purifying agent. Flux serves three different purposes simultaneously. First, it purifies the components you're soldering by cleaning them of any rust. It also closes out any extra air that might come into contact with the material, thus preventing future rust. Finally, it improves the dripping individuality of the solder itself.\n\n3. Perf Board: Perfboards are also called Perforated Circuit Boards, Prototyping Boards, and Dot PCBs. It's basically a bunch of copper pads on circuit board material, usually on one side but the copper pads can be on both sides.\n\n4. Helping Hands: A helping hand is generally a stand with flexible clamps that hold objects in place which leaves you hands free to carry on with your work.\n\n5. Precision Tweezers: Anti-magnetic stainless steel general-purpose tweezers offer precision tip symmetry and balance with good corrosion resistance to most chemicals and acids.\n\n6. Solder: Solder is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling.\n- - - - - -\n## The Soldering Process\nStep 1: If the perf board is full, desolder it by using a desoldering wick.\n\nStep 2: Place the perf board on the helping hand for better precision.\n\nStep 3: Place the required LED on to the perf board, on a side without copper pads.\n\nStep 4: Bend the leads to follow the path you want them to have. Add a bit of solder to both ends of that lead to hold it in place.\n\n- - - - - - -\n## Image of soldered LED on perf Board:\n\n# TASK 13:\n\n Design a 555 astable multivibrator with a duty cycle 60%, rig up the circuit on a breadboard, and by using the probes observe the output of your circuit on the DSO.\n\n\n\n\n\nBasic Astable 555 Oscillator: The 555 IC can function as an astable oscillator to generate continuous square wave pulses. It operates by continuously re-triggering itself, allowing it to function as a free-running oscillator.\n \n\n\n\ncircuit configuration: Connect pins 2 (trigger) and 6 (threshold) together to enable re-triggering for astable operation. The timing resistor from the monostable circuit is split into two resistors, R1 and R2.\n\n\n\nWaveform Generation: During each cycle, the capacitor charges through both R1 and R2 but discharges only through R2. Output waveform voltage level is approximately Vcc−1.5V.\n\n\n\n\nCharge and Discharge Times: Charge time (t1) and discharge time (t2) determine the frequency of oscillations. T=t1+t2, where T is the total periodic time.\n\n\n\nOutput Frequency Equation: f=1/T=1/(t1+t2).\n\n\n\n\n\nDuty Cycle Adjustment: The duty cycle can be adjusted by changing the ratio of resistors R2 to R1. The duty cycle is the ratio of the "ON" time to the "OFF" time.\n\n\n\n\n - - - - \n\n\n\n\n- - - - - \n\n\n\n\n\nSummary\n\nThe 555 IC in astable mode generates stable square wave output. Duty cycle can be adjusted for specific applications. The 50% duty cycle can be achieved by modifying the circuit configuration. Changing resistor and capacitor values alters the oscillation frequency.\n\n- - - -\n# TASK 14:K-Maps and Deriving the Logic Circuit\n- - - - -\n## Working Condition of Burglar system\nLet us assume there are two switches, one for the door and the other for an alarm that they must remember to press. Assume that the door opened as 0 and closed as 1; Assume that the alarm pressed is 1 and not pressed is 0;\n\nOne would naturally assume that the burglar opens the door and forgets to press the alarm. So the underlying logic is that the buzzer must ring when both the door is opened and the alarm is not pressed. i.e., 0 and 0 cases.\nOnly a NOR gate gives the necessary output of 1 when both the inputs are 0.\n - - - -\n## Implementation using TinkerCAD:\n\n1. Take an IC 7432 for the OR gate and an IC 7404 for Inverting and connect them in series to form a NOR gate. Make sure they are not grounded together.\n2. Take 2 slide switches to regulate the input. Give them as input to the OR gate.\n3. Give the Regulated Power Supply and ground all the necessary components.\n4. Connect the output of the entire NOR gate to the Piezo buzzer which gives the required output as a buzzer audio.\n5. In the same fashion, connect an LED for additional safety.\n6. Test out all the input conditions and verify it's working.\n- - - - -\n## TinkerCAD simulation:\nhttps://www.tinkercad.com/things/kMtsPK8Hzbl-navyas-burgler-alarm-?sharecode=JOws2WCbPUB-gaydjKYdQxQDuagTqpedBmoqTpNw47I\n## Circuit Diagram:\n\n# TASK 15-Active Participation\n- - - -\n \nAt the Generation Tech event, we leveraged Moqups to design an innovative app centered around the crucial theme of quality education, aligning with the United Nations' Sustainable Development Goal on education. Our project aimed to address challenges and enhance accessibility, ensuring quality education for all. Through Moqups, we crafted a user-friendly interface that encapsulated our vision for a transformative education
