Hi Friends! Happy to see you here. I welcome you on board. In this post, I’ll walk you through the Introduction to BC639. BC639 is a high current gain bipolar junction transistor that falls under the NPN transistor family. It constitutes a high collector current and low collector-emitter saturation voltage and is widely used for amplification and switching purposes. It is used to drive load under 500mA. Collector Dissipation is 0.625W while DC Current Gain (hfe) ranges from - 40 to 160 with transition frequency 200MHz. In this post, I’m going to discuss all nitty-gritty of the BC639 transistor covering pinout, working, power ratings, alternatives, applications, and physical dimensions.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, we will have a look at the DHT11 Arduino Interfacing. DHT11 is an embedded sensor, used to measure both temperature and humidity of the surroundings. It is made up of two different parts i.e. capacitive humidity sensor and a thermistor. DHT11 is a slow sensor but is quite efficient for the applications where we need to do some basic analog data exchange. There is a small chip inside this sensor which performs the function of analog to digital to analog conversion and gives the results for temperature as well as for humidity in digital form. This digital signal can be read easily through any micro-controller.
LM335 is another temperature sensor and to understand today's p ...

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to BD139. BD139 is a Bipolar NPN transistor, it is mounted in the SOT-32 plastic package. It is designed for audio amplifier and driver utilizing complementary circuits. BD139 has a gain value of 40 to 160, which determine the amplification capacity of a transistor. It has three main pinouts which are a collector, base and emitter. It is used to control (On/Off) bigger loads that consume less than 1.5A.
BD139 is used in different industrial projects such as RF amplifier and Switching Circuits. In today's post, we will have a look at its pinout, Arduino interfacing, applications, Specifications, etc. I will also share some links whe ...
Hello Everyone! I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to FDB301N.The FDV301N is an N-channel MOSFET using Fairchild's proprietary and high cell density, DMOS technology. The cell’s high density helps to minimize the on-state resistance. This device is mainly developed for low-voltage applications. This N-channel MOSFET replaces different digital transistors and provides different bias resistor values.

Although 3D printing feels like a relatively new development, there are lots of promising projects underway. A scheme to build 46 eco-homes has been approved in the UK’s first 3D printed development
, for example, and the same is happening in Australia to provide housing for remote indigenous communities in rural areas
.
But how can 3D printing be applied in business? Here’s a breakdown on how it can be used and the opportunities it creates.
What is 3D printing?
3D printing refers to technology that can form materials using computer designs. The earliest signs of 3D printing came about in 1981. Dr. Hideo Kodama created a rapid prototyping machine that built solid parts using a resin and a layer-by-layer system.
Using a bottom-up technique, the material is layered until a tangib ...
Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hi Friends! I hope you are doing well. Welcome you onboard. Today, I'll discuss the basic Introduction to HC-SR04 Ultrasonic Sensor. It is an ultrasonic sensor, also known as an ultrasonic transducer that is based on a transmitter and receiver and mainly used to determine the distance from the target object.
The amount of time it takes to send and receive waves will determine how far the object is placed from the sensor. It mainly depends on the sound waves working on “non-contact” technology. The required distance of the target object is measured without any damage, giving you accurate and precise details.
This sensor comes with a range between 2cm to 400cm and is used in a wide range of applications including speed and direction measurement, wireless charging, humidifiers, medical ...
