Building a Fun and Smart Home with a DIY Smart Doorbell

  Title: Building a Fun and Smart Home with a DIY Smart Doorbell Introduction: In the exciting world of electronics, there's nothing quite as thrilling as creating your very own smart home gadgets. Today, we'll embark on a journey to build a Smart Doorbell using simple and easily accessible equipment like the Arduino Uno, an IR proximity sensor, and a buzzer. This DIY project is not only a fantastic introduction to electronics but also a step towards transforming your home into a tech-savvy haven. So, gear up, young inventors, as we venture into the world of smart homes! Materials You'll Need: 1. Arduino Uno: The brain of our smart doorbell, capable of processing information and controlling the connected devices. 2. IR Proximity Sensor: A nifty gadget that detects the presence of objects in its vicinity. 3. Buzzer: This component will be the voice of our smart doorbell, alerting you when someone approaches. Step 1: Setting Up the Arduino Uno: Begin by connecting your Arduin...

Seaborn

Seaborn is a Python data visualization library built on the matplotlib library. (i.e., it runs matplotlib at the backend and so accepts some keyword argument used in matplotlib). seaborn is a dataset-oriented visualization library. Its plotting functions operate on data frames and arrays containing whole datasets and internally perform the necessary semantic mapping and statistical aggregation to produce informative plots. The Seaborn library aims at creating informative plots with fewer lines of code. 

It also has the following features. 
 * Aesthetic styling and colour palette 
* It is dataset oriented, i.e., works well for matrices, data frames, etc. 
* It functions well with pandas and NumPy data structures 
* Create statistical plots with fewer lines of code.

  Getting Started 
Install the Seaborn library into your Python environment. make sure you have matplotlib installed also since the seaborn library runs off the matplotlib library. 

 `pip install seaborn 

 #This installs the latest version of the Seaborn library Seaborn Plots
The seaborn library is used to visualize data, it is also used to create a variety of plots and visualize data in different formats (data frame, matrices, NumPy array, etc). 

The focus of this article is to discuss the different kinds of plots you can visualize with Seaborn and why and when to use a particular plot type. Seaborn can be used to create the following plots. 

* Scatter plots 
*Distribution plots 
*Categorical plots 
*Comparison plots 
*Seaborn Grids 
*Matrix plots 

 Scatter plots with Seaborn Scatter plots are plots that show the relationship between two continuous features. (i.e., say Two features Age and Salary in a dataset).

 #import the library with an alias 
import seaborn as sns 
import pandas as pd 

 data = {"acceleration":[23,34,45,23,56,34,54,34,56], "mpg": [12,22,33,11,37,23,39,21,38] } 

 #create a data frame from the dictionary 
df = pd.DataFrame(data) 
 #plot a scatterplot using seaborn scatterplot() 
 #x- the values/column to be plotted on the x-axis #y- the values/column to be plotted on the y-axis #data - the data frame of reference
 sns.scatterplot(x="acceleration", y="mpg", data=df )

How DC motor works and control.

Introduction to DC motors A DC motor is an electric motor that converts direct current electrical energy into mechanical energy. They operate based on the principle of "Force acting on a coil of wire in a magnetic field". This principle states that when a current-carrying conductor is placed in a magnetic field, the conductor experiences a mechanical force. The direction of this force is determined by Fleming's left-hand rule, and the magnitude of the force can be expressed as:                   F= B*I*L ( in newtons) where  F- force(newtons) B- magnetic field (Tesla) I- Current ( Ampere) L- Length of the conductor. According to Fleming's left-hand rule, the direction of the force is perpendicular to both the conductor and the magnetic field.   Tip: if the direction of current flow is reversed, the direction of rotation of the motor changes also. Controlling DC motors DC motors find use in various applications where ope...

Flame Detectors Explained

 Flame sensor/ detectors: Flame detectors(sensors) detect the presence of flame.  just as every other sensor operate ; they detect a change in a physical phenomenon and then produce an output signal proportional to the change in the physical phenomenon being sensed or detected. The presence of fire which relates to flames is a physical condition to be watched against  and since this is an unwanted condition , there arise the need to constantly watch(detect) against it and eliminate it as quick as possible when detected . Flame detectors are devices that watch against flames (fire ) , it may also be called a fire detector.  A flame sensor detects a flame but what physical or measureable characteristics of a flame does it detects??. with this question in mind , we need to overview flames , identify the properties of a flame that can be detected /measured / sensed  and work on the best methodology to detect flames. OVERVIEW OF FLAMES A flame is a mixture of reac...

Astable multivibrator

Astable multivibrator Astable Multivibrators are free running oscillators which oscillate between two states continually producing two square wave output waveforms.            Introduction  Regenerative switching circuits such as  Astable Multivibrators   are the most commonly used type of relaxation oscillator because not only are they simple, reliable and ease of construction they also produce a constant square wave output waveform. Unlike the Monostable Multivibrator or the Bistable Multivibrator we looked at in the previous tutorials that require an “external” trigger pulse for their operation, the  Astable Multivibrator  has automatic built in triggering which switches it continuously between its two unstable states both set and reset. The  Astable Multivibrator  is another type of cross-coupled transistor switching circuit that has  NO  stable output states as it changes from one state to the other all ...
