Today, we are gonna have a look on How to Interface Ultrasonic Sensor with Arduino. Few days ago, I have posted a complete tutorial on How to Use Ultrasonic Sensor Library in Proteus and later I have posted different examples on How to Simulate Ultrasonic Sensor in Proteus. Those posts were about Proteus Simulations and weren't about hardware interfacing, so I thought today let's interface it in hardware.
Simulation is a good starting point for projects but they are really far away from real world. It happened to me a lot of times that my simulations are working perfectly fine but when I design the same circuit in hardware then it says no I am not gonna work. :) So, the bottom line is never trust simulations, unless you properly test it on hardwar ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
Hey Everyone! I hope you all are doing great and enjoying life. I am back to give you daily dose of some valuable information so you can progress and grow in your relevant field. Today, I am going to unlock the details on the Introduction to 2n2905. It is a PNP (Positive-negative-Positive) bipolar junction transistor (BJT) which is mainly used for general purpose and switching applications. In this transistor, N doped semiconductor exists between the two layers of P doped material. I am going to give you brief details about this transistor. Let's get started.
Introduction to 2n2905
2n2905 is a PNP bipolar junction transistor which is mainly designed for general purpose, small signal and switching applications.
It comes in TO-39 casing an ...
Hello friends, i hope you all are fine and enjoying. Today i am going to share a new tutorial which is Interfacing Arduino with HC05 Bluetooth module. First of all lets have a little introduction about HC-05 Bluetooth module. HC-05 is a bluetooth module, which was designed for wireless data communication. This little module is capable of both sending and receiving data but it performs only one thing at a time, which means at a particular time it can only send or receive data but can't do the both tasks.
In order to send or to receive data, you have to make one module as a master and the other module as a slave. If both the modules are acting as master then, data will not transmit and if both the modules are acting as a slave then, again data will ...
Hello friends, hope you are having fun. In today's post, we will have a look at Serial Communication with 8051 Microcontroller in Proteus ISIS. In the previous post, we have seen a detailed post on LED Blinking Project using 8051 Microcontroller in Proteus ISIS, which was quite a simple tutorial. And I hope if you are new to 8051 Microcontroller then from that post you must have got some idea about C Programming of 8051 Microcontroller.
Now, today we are gonna go a little further and will have a look at Serial Communication with 8051 Microcontroller and we will also design the simulation of this project in Proteus ISIS software. 8051 Microcontroller also supports Serial port similar to Arduino and PIC Microcontroller. And the communication protoco ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explain you about Introduction to TL431. TL 431 are programmable shunt regulator diodes having three terminals. Its a low temperature coefficient diode and can be programmed from reference voltage (Vref) up to 36V when it is attached to 2 external resistors.
TL 431 has an impedance of 0.22 ohms and has a current range from 1mA to 100mA. In several different applications zener diodes can be replaced with TL 431 diode due to its efficiency. These applications include power supplies, Operational Amplifier (Op-amp) circuitry and digital voltmeters. TL-431 can either be used as positive or as negative voltage reference because it operates as shunt regulator. T ...
Hello friends, hope you all are fine and having fun with your lives. Today I am going to share a problem and also its solution with you guys. A few days ago, I bought new NRF24L01 modules as they were needed for a project. So, today when I started working on them, I encountered a very strange problem. When I interfaced my NRF24L01 with Arduino and uploaded the transmitting and receving codes in them, I couldn't get anything on my serial terminal as I explained in my previous post Interfacing of NRF24L01 with Arduino. That was quite strange for me as I have worked on this module many times and it never troubled me before. So I keep on working on it but no luck. I even changed my RF modules as I thought may be they are faulty modules but still no lu ...
In the previous post we have seen the project description of Voice Recognition Project using EasyVR shield. Today we will have a look at Getting started with EasyVR commander. EasyVR shield is a module which is used for voice recognition. First of all, we save our commands in the EasyVR shield and then we use these commands to control anything. In this project, I need to control the robot with voice commands like when someone says FORWARD then the robot start moving in forward direction.
Now first of all what I need to do is to save this FORWARD voice in the shield, which we will see today how to save the command in the shield and after that I will show you the Interfacing of EasyVR shield with Arduino UNO. So that when I say Forward the motor sta ...
Hey Everyone! I hope you all are having fun and looking forward for happy weekend. I am here to give you a daily dose of sound knowledge so you can develop some skills in engineering field. Today, I am going to uncover the details on the Introduction to 2sa1215. It is bipolar silicon PNP (positive-negative-positive) transistor. It is made up of two layers of P doped material and one layer of N doped material. I'll give you the brief overview of this device, what it does and what are its major applications? Let's hop on the board and dive into the details of this PNP transistor.

Hey Guys! I hope you all are doing great. In the previous tutorial, we studied the basics of Semiconductors, where we briefly discussed the PN Junction. Today, we are going to have a detailed overview of PN Junction.
But before getting into the details of PN Junction, we need to first recall a few concepts from the previous lecture:
Semiconductor Basics
As we know, the conductive power of a semiconductor material lies between a conductor and an insulator. So, it can act as a pure conductor as well as a pure insulator, depending on the applied conditions. Semiconductors are divided into two types:
Intrinsic Semiconductor.
Extrinsic Semiconductor.
Intrinsic Semiconductor
A semiconductor in its pure form is called an Intrinsic semiconductor. In this state, the outermost valan ...
