Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to given elaboration on Introduction to L293D. L 293D is basically a high current dual motor driver/controller Integrated Circuit (IC). It is able to drive load having current up to 1A at the voltage ranging from 4.5V to 36V. Motor driver usually act as current amplifier because they receive a low current signal as an input and provides high current signal at the output.
Motors usually operates on this higher current. L-293D has to builtin H-Bridge driver circuits and is able to control two DC motors at a time in both clockwise and counter clockwise direction. It has two enable pins and they should be kept high in order to control the motor. By changing the p ...
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 ...
Hey Guys! Hope you are doing well. Welcome you onboard. Today, I'll discuss the details on the Introduction to CR2032 Battery. It is known as a coin cell or button cell that comes in cylindrical form and is mainly used in pocket calculators, wrist watches, artificial cardiac pacemakers, hearing aids, and automobile key-less entry transmitters.
Low self-discharge and an ability to retain a charge for a long time make this device a good pick for high power devices. More often than not, it is called a lithium energizer where high capacity is a major concern. It falls under the category of disposable primary cells, where common cathode material is a silver oxide, manganese dioxide, or carbon monofluoride and common anode materials are zinc or lithium ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to tell you guys about Introduction to LM2902. LM2902 basically has four (4) internal builtin operational amplifiers. There builtin amplifiers are internally frequency compensated. The basic purpose behind designing this type of device is to support control systems in industries as well as automotive applications. LM-2902 is capable of operating for a wide range of voltages using a single power supply source.
Moreover, we can also operate this device from a split power source. Low current drain supply and magnitude of the power supply source, both are totally independent to each other. LM-2902 has a lot of features which make it different from the standard g ...
Hey Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can always stay ahead of your competitors. I have previously updated the article on NPN transistor that is used for amplification and switching purpose. Today, I am going to unveil the details on the Introduction to PNP Transistor which falls under the category of bipolar junction transistors and comes with three layers i.e. two P-doped layers and one N-doped layer where an N-doped layer exists between two P-doped layers.
Main Function: Small current at one terminal is used to control large current at other terminals.
Major Charge Carriers: Holes
These NPN and PNP transistors come with their own benefits based on the nature of the e ...
Hi Guys! We welcome you on board. Electronic components play an important role in the designing and working of electronic projects. I have already discussed a number of articles on electronic components covering transistors, MOSFET, and FETs. I am going to continue the thread relating to transistors, because they are the building blocks for amplification and switching purpose. Today, I am going to cover the details on the Introduction to BC182L. It is an NPN (negative-positive-negative) general purpose bipolar transistor which is mainly used for switching and amplification purpose for the low demanding workloads. I'll try to highlight the main features of this component, so you can grab the main concept, what is this about and what are its main ap ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain the Relay Interfacing with Microcontroller using ULN2003A. In the previous lecture, we have discussed the detailed Introduction to Relay along with its working. Now we are going to practically interface the relay with a microcontroller to design an automatic switch. Relay is a key component in almost every electronic circuit. It can be
used as a switch and can also be used as a voltage regulator.The microcontroller I am going to use here is PIC18F4552 but you can use any other Microcontroller. You just need to change the syntax of coding but the logic will remain the same. Here, I am using ULN2003A to control the relay and from this relay, we can control anything.So, let's get started:
Relay Inte ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention.
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32.
We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hello Everyone! Happy to see you around. Thank you for clicking this read. In this post today, I’ll document the Introduction to MJE13007.
MJE13007 is an NPN bipolar junction transistor that is a semiconductor device made of silicon material. This chip is mainly used for amplification and switching purposes. The collector-base voltage is 700V while the collector-emitter voltage is 400V. The power dissipation at temp 25C is 80W. This means 80W is released during the working of this device. This device can support load up to 8A because the current at the collector side is 8A.
