Hello everyone! I hope you all will be absolutely fine and having fun. I am going to give you the detailed discussion about Introduction to UC3843 today. UC 843 is basically a current mode Pulse Width Modulation (PWM) controller having fixed frequency. It is basically designed for DC to DC converter purposes as well as off line applications and it requires minimum external components. UC-3843 has three different packages which will be explained later.
UC-3843 has several different features which make it ideal and useful for a lot of real life applications. These features may include trimmed oscillator for the control of accurate duty cycle, high gain amplifier and to control power MOSFET, there is a high current totem-pole output. Moreover, some ...
Hi Guys! Hope you are doing well. Welcome you onboard. Today, I'll unlock the detailed Introduction to 2sa1265 which is a PNP transistor mainly used for power amplifier applications and proves to be an ideal choice for 70W high fidelity audio frequency amplifier output stage applications.
This PNP transistor falls under the category of Bipolar Junction Transistors where two charge carriers i.e. electrons and holes take part in the conduction process, however, holes are major charge carriers in the PNP transistors, unlike NPN transistors where electrons are the major charge carriers.
BJTs are different than that unipolar transistors like JFETs as former is the current controlled device and later is a voltage controlled device. Both are used in ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you about how to make a simple program for DC Motor Direction Control using Arduino. The word DC is basically an abbreviation of Direct current. So, a direct current motor is commonly used motor having two input terminals, one is positive and the other one is negative. If we connect these terminals with the voltage supply the motor will rotate. If you change the polarity then motor will rotate in opposite direction. You should also have a look at Difference between DC & AC Motors to get a better idea about these motors.
DC motor has a lot of applications. You can use it in automation projects, for controlling static as wel ...
Update: I have updated the code and removed the bug. Thanks for informing. Now this code will work perfectly.

Hello friends, hope you all are fine and having good health. Today, as the name suggests, I am gonna post on how to Receive SMS with AT Commands using Sim900 and Arduino. I have already posted a tutorial on How to Send SMS with Arduino UNO and Sim900, so now we are gonna check the opposite. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. But receiving a text message on your SIM900 shield is a bit difficult because now you need to place a check when user will send a message. So, ideally whenever anyone send a message to yo ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Ultrasonic Sensor Arduino Interfacing. I would like to tell you some detail about ultrasonic sensor, after that we will move towards ultrasonic sensor Arduino interfacing. Ultrasonic sensor is also known as SONAR sensor. SONAR basically stands for Sound Navigation and Ranging. Ultrasonic is mostly used for the distance measurements. It can also be used for measuring the depth of the sea.
I have already shared Ultrasonic Sensor Library for Proteus. Ultrasonic/SONAR sensor is an electronic device used to estimate the distance of an object by continuously transmitting sound waves at a particular frequency and listens to tha ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new IR Proximity Sensor Library for Proteus. Proximity Sensors are not available in Proteus and we are sharing its Proteus library for the first time. So far, I have only shared Proteus Libraries of digital sensors but today I am sharing an analog sensor, so too excited about it.
In the next few days, I will keep on sharing Proteus Libraries of different analog sensors, so if you want any sensor in Proteus, then let me know in the comments. IR Proximity Sensors are used to detect hurdles/obstacles placed in their path. They are normally used on robots for path navigation and obstacle avoidance. So, let's have a look at How to download and simulate IR Proximit ...

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 1N4007. It is a PN junction diode. Diodes can be made by combining two different types of semiconductor e.g. P and N. PN junction is a junction formed between P and N types of semiconductors. You guys should also have a look at Introduction to 1N4148.
1N 4007 belongs to the series of 1NXXXX devices. Its an American standard numbering system standard used for semiconductor devices. This standard has been adopted globally now. In 1N 4007 the first part 1N indicates single junction semiconductor. 1N indicates 1 junction whereas N indicates the semiconductor diode. 4007 is the specific number to indicate the particular ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to DS3231. DS3231 is a real-time clock (RTC) with an integrated temperature-compensated crystal oscillator. It consists of a battery that provides supply to DS3231 when the main supply is off. In this way, it continues working without any interference. It is available in industrial and commercial temperature ranges. It exists in a 16-pin, 300-mil SO package.
DS3231 is used in industrial projects and different electronic devices such as laptops, computers, and GPS for high accuracy of time. In today's post, we will have a look at its working, pinout, applications, protocol, etc. I will also share some links to projects where I have interfaced it with some oth ...
