HOME AUTOMATION

                      A home automation system is a technological solution that enables automating the bulk of electronic, electrical and technology-based tasks within a home. It uses a combination of hardware and software technologies that enable control and management over appliances and devices within a home.

Here, I have used Relay, Nodemcu and electrical appliance.

SMART GARBAGE MONITORING SYSTEM USING INTERNET OF THINGS (IoT)

                     The circuit is designed by using Nodemcu, Arduino, and Ultrasonic Sensor.

CONTROLLING TWO DC MOTORS WITH THE HELP OF ARDUINO AND MATLAB GUI

In this video, you will learn about how to create a graphical user interface in Matlab to control two DC motors connected to Arduino + L293d. The connection and programming are shown in video.

Homo polar motor from battery || science fair project ||

A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field.

Non-contact voltage tester || AC voltage detector || BIJEN

A non-contact voltage tester is a very useful tool for anyone working on or near electrical circuits.

Three Transistors are connected together in such a way that they can detect the flow of current in the wires.

TOUCH SENSOR

BC547 is an NPN bipolar junction transistor. A transistor stands for transfer of resistance, is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals. ... Its equivalent transistors are BC548 and BC549.

CONTROLLING THE LED WITH THE HELP OF MATLAB (GUI)

WATER LEVEL INDICATOR

Here, the (X) numbers of BC47 transistors can be used to make the circuit.

where all the emitters of the transistors are connected together and the base of the transistor are connected in the water tank. Moreover, all the collectors are then connected to the negative terminal of a respective bulb.    

DISPLAYING CLOCK IN LCD USING ARDUINO

                         Here, I haven't used the Real-Time Clock module. The time on the Arduino is showing the same time as the computer.
