Hello geeks, welcome to our new project. In this project, we are going to make a very useful and interesting electronics tool that we as engineers or tinkers need in everyday life. We use the capacitor in most of our projects for various purposes such as filters or power supplies. Most of the time, we do not have a provision to measure the capacitor value in our digital multimeter. So, this time we came up with the solution. Hence, we will make our own capacitance measurement tool using Arduino.
Rather than investing in new electronic equipment, we will use an Arduino board and some basic components to measure the capacitance. To make this project, we should have some working knowledge about the capacitor. Here, we will not discuss the in-depth wo ...
Hey Friends! Hope you are doing great. I am here to provide you the technical knowledge that helps you stay ahead of your competitors. Today, I am going to unlock the details on the Introduction to 2n5884. It is a power PNP bipolar junction transistor mainly used for general purpose amplification and switching purpose. This is a complementary silicon epitaxial-base transistor that can support 25 A and 80 V. I'll discuss each and everything related to this transistor i.e. what it does, its pinout, circuit diagram and main applications.
You must have a look at comprehensive read on Introduction to Bipolar Transistor if you are unsure how these bipolar transistors work.
Before we dive into the details of this PNP transistor we must be aware what is ...
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 ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hi Guys! Hope you are doing well. We always strive to give the most relevant information as per your needs and demands. Today, I'll discuss the details on the Introduction to RJ45. It is a type of standard connector mainly used for data transmission.
Almost all ethernet cables come with this connector on each end, and they, sometimes, known as RJ cables. The RJ in the connector stands for registered jack while 45 defines the number of interface standard.
In this post, I'll cover each and everything related to RJ45, why it used, features, and main applications. Let's dive right in and nail down everything you need to know.
Introduction to RJ45
RJ45 is a type of connector, mainly used for Ethernet networking including connection with PC network cards, data switches, WiFi access p ...
Hello friends, i hope you all are fine and enjoying. Today i am going to share a new tutorial in which I am gonna explain What is 555 timer? We all know about 555 timer, which is an 8-pin IC (integrated circuit), most commonly used in electronic projects, built now a days. As you can see fron its name that it is a timer and designed to generate PWM.
In today's tutorial i am going to explain, what's hidden inside this 555 timer IC and what is 555 timer. A 555 timer is a much compatible electronic device and the biggest feature of this IC is that it able to work on both analogue and digital techniques. Now if we simply consider the output of the 555 timer then, at any particular time, this timer has only 1 definite state. Which means at any time, it ...
Hi everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to P6KE220A.The P6KE200A is a transient voltage suppressor (TVS) diode that uses clamping action to provide circuit protection against overvoltage. It is widely used in low-voltage supplied ICs and MOS technology due to its quick response to transient overvoltages. For P6KE200A the clamping voltage is 246V and the breakdown voltage is ranged from 190V to 210V.
I suggest you read this entire post till the end as I’ll detail the complete introduction to P6KE200A covering datasheet, pinout, features equivalents, and applications of this component P6KE200A.

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 ...
