Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to use Arduino PWM Pins. It's the next tutorial in our new Arduino Tutorial for Beginners series. We will design a small code in which we will be controlling a dc motor's speed using the Arduino PWM Pins but before going into the details, let me first give you an introduction to Arduino PWM Pins because without understanding the PWM, which is the abbreviation of Pulse Width Modulation, you won't be able to understand How to use Arduino PWM Pins. In our previous tutorial, we have seen How to use analogWrite in Arduino and I have told you in that tutorial that we use this command for PWM as well. So, today we will have a look at How to do that.
PWM is an a ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Introduction to Laser Sensor. Laser sensor is basically an electronic device which we often use for the detection of accurate positions as well as small objects. Laser sensors transmit or radiate laser light. This laser light consists of light waves having same wave length. Due to this fact laser light travels in a parallel direction from the source emitting this light. Due to its travel in parallel direction it can be transmitted over long distances. This light is dangerous for the human beings.
We must avoid by looking directly into the light. It causes serious eye damaging effect and even can make anyone blind. As we ...
Hey Fellas! We welcome you on board. I am back to give you a daily dose of useful information that resonates with your needs and expectations and put you ahead from others. Today, I am going to uncover the details on the Introduction to 2n3773. It is an NPN (negative-positive-negative) power base bipolar junction transistor which is mainly used for disk head positioners, high power audio, and other linear applications.
I'll try cover each and every feature related to this transistor so you don't need to go anywhere and you find all information in one place. Let's jump in and explore what is it about and what are its main applications?

Hello friends, hope you all are fine and having fun with your lives. Today's post is about interfacing of RFID module RC522 with Arduino. RC522 is very simple yet effective module. It is an RFID module and is used for scanning RFID cards. Its a new technology and is expanding day by day. Now-a-days it is extensively used in offices where employees are issued an RFID card and their attendance is marked when they touch their card to rfid reader. We have seen it in many movies that when someone places ones card over some machine then door opens or closes. In short, its a new emerging technology which is quite useful.
I recently get a chance to work on a project in which I have to use RFID reader to scan cards. In this project I have used it for for s ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you a detailed Introduction to MAX232. It is an Integrated Circuit(IC) embedded in a single chip and acts as a voltage-level converter. MAX 232 is capable of converting 5V TTL Logic level to TIA/EIA-232-F level and can take up to +-30V input. It is normally used for the communication between microcontroller and Laptop/PC.We can use MAX-232 to convert Transistor Transistor Logic (TTL) voltage level to RS232 and vice versa. RS232 is the method of transferring data using serial communication. MAX 232 is a dual receiver or driver having a capacitive voltage generator to supply RS232 voltage levels from a single supply of 5V. Each receiver converts RS232 inputs to 5V either Transistor Transistor Logic (TTL) ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a very basic and introductory tutorial named How to use Arduino Serial Read. I am sharing this tutorial because I am getting a lot of emails in which users normally ask about basic Arduino tutorials as they are very new to them. So, I thought of sharing this very basic Arduino tutorial in which we are going to have a look at how we can use the Arduino Serial Read command.
I selected this tutorial as my first tutorial in this list of Arduino basic tutorials because learning to use Serial port is very necessary as it's one of the best troubleshooting tools for your code. I have also given a Proteus Simulation in which I have received the incoming data f ...
Hello Everyone! I welcome you on board. Hope you’re well today. In this post today, I’ll detail the Introduction to FR106.The Fr106 is a fast recovery diode mainly employed in fast-switching applications. It supports loads under 1A and carries a peak inverse voltage of 800 V.
I suggest you read this post all the way through as I’ll walk you through the complete Introduction to FR106 covering datasheet, pinout, features, characteristics, and applications. Let’s jump right in.
Introduction to FR106
Fr106 is commonly known as a fast recovery diode mainly employed in fast-switching applications. This is a two-terminal device named anode and cathode.
The gray-colored band at one side of the diode indicates the cathode side while the other side is the anode terminal.

Hello friends, today's post as the name suggests is about how to send SMS with Arduino UNO and SIM900D using AT Commands. There are different types of SIM900D modules available in the market, so it doesn't matter which module you are using. All SIM900D modules work at AT commands basically so today I am going to show you how to send an SMS via AT commands without using any Arduino library. You should first read the AT commands manual which will give you an idea about AT commands. AT commands are special sets of commands which are used for communicating with SIM900 module. Using these AT commands we let our GSM work for us. Like if you want to send SMS then there's a specific AT command for sending the SMS similarly if you want to change the PIN co ...
Hi Everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the Introduction to BSS138.The BSS138 is an N-Channel Logic Level Enhancement Mode Field Effect Transistor that is available in surface mount package SOT-23. It features a low input capacitance of around 40pF and a low on-state resistance of around 3.5.
