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 everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you detailed discussion on Introduction to LM2904. LM 2904 consists of two builtin amplifiers. These amplifiers have high gain and they are internally frequency compensated. These amplifiers are designed for the operation from a single power supply for a large range of voltages. We can also operate them from multiply power supplies as well.
LM-2904 operates on 3.3V power supply, it is the most common power supply in digital systems. LM 2904 is also available in small sizes i.e. they are available in the latest technology DSBGA. LM-2904 has a lot unique features in comparison to the other standard amplifiers. These features include large DC voltage ga ...
Hello readers, I hope you all are doing great. In our previous tutorial, we learned SMTP server and how to implement an SMTP server for sending emails with ESP32. In the previous tutorial, we also demonstrated some examples like sharing raw text, HTML text, images and text files.
So, at the transmitter end, we are using the SMTP server.
But, what about the receiver end?
At the receiver end, we use another protocol called IMAP (or Internet Message Access Protocol) and POP3 (Post office Protocol V3) for receiving the emails.
Fig. IMAP and SMTP
What is IMAP Protocol and How does it Work?
IMAP is an application layer (TCP/IP) protocol that is used at the receiver end to receive emails from SMTP server or mail server. IMAP follows the client/server mo ...
Thank you for being here for today's tutorial of our in-depth Raspberry Pi programming tutorial. The previous tutorial taught us how to install a PIR sensor on a Raspberry Pi 4 to create a motion detector. However, this tutorial will teach you how to connect a single seven-segment display to a Raspberry Pi 4. In the following sections, we will show you how to connect a Raspberry Pi to a 4-digit Seven-Segment Display Module so that the time can be shown on it.
Seven-segment displays are a simple type of Display that use eight light-emitting diodes to show off decimal numbers. It's common to find it in gadgets like digital clocks, calculators, and electronic meters that show numbers. Raspberry Pi, built around an ARM chip, is widely acknowledged as ...
Hello readers, hope you all are doing great. In this tutorial, we will discuss low power modes in ESP32, their purpose and their implementation to increase the battery life by reducing power consumption.
Purpose of Low Power Modes
Fig.1
Along with multiple wireless and processing features, ESP32 also provides us with a power-saving feature by offering sleep modes. When you are powering the ESP32 module from the live supply using an adaptor or a USB cable, there is nothing to worry about power consumption. But when you are using a battery, as a power source to ESP32, you need to manage the power consumption for longer battery life.
Low Power Modes in ESP32
When ESP32 is in sleep mode, a small amount of power is required to maintain the state of ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP127. The TIP127 is a PNP type Darlington pair transistor. It is manufactured for universal drive amplifications and less velocity swapping submissions. It is existing in TO-220 kind of cascading. Its corresponding NPN transistor is the TIP122.
This is a common transistor it used in varied engineering schemes. It formed for least time taking swap proposals. In today’s post, we will have a look at its protection, wreck, difference, entitlements, etc. I will also share some links where I have connected it with other microcontrollers. You can also get more material about it in comments, I will guide you more about it. So, let’s g ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to MPR121. MPR121 is a touch sensor controller, its working is like the capacitor's working principle. This module has twelve electrodes points, it communicates via I2C protocol. When any objects come closer to an electrode point, we can observe the presence of an object by variation in capacitance of an electrode. It's working voltage should be between 2.5 to 3.6 VDC.
MPR121 is used in different industrial projects and electronic devices such as mobile phone and remote control systems. In today's post, we will have a look at its working, pinout, protocol, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have ...
Hi Guys! I welcome you on board. In this post today, we’ll discuss the KSC1845 NPN Transistor. We will have a look at the KSC1845 Datasheet, Pinout, Power Ratings, Equivalents & Applications in detail. As it's an NPN transistor, electrons are the majority charge carriers and thus play a major role in conductivity. KSC1845 is mainly used for fast-switching and amplification purposes.NPN transistor carries 3 terminals, known as:
Emitter
Collector
Base
If the applied voltage at the base terminal exceeds 0.7V, it will forward bias this NPN transistor and the current will start to flow from Collector to Emitter. If the base voltage is less than 0.7V, KSC1845 will remain in the reverse-biased state.
I suggest you buckle up as I’ll discuss the KSC1845 ...
Hi Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to UF5408.
The UF5408 is an ultra-fast recovery diode that comes with quick recovery time. It is mainly used to rectify the sine waves. Upon rectifying the signal it converts the AC signal into a DC signal. This diode provides the DC signal to the electronic device since most of the electronic devices operate on the DC signal.
Just stay with me for a little while as I’ll discuss the complete Introduction to UF5408 covering datasheet, pinout, features, and applications of this component UF5408.
Let’s get started.

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 ...
