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 ...
Hi Guys! Hope you’re well. I welcome you on board. Thank you for viewing this read. In this post today, I’ll walk you through the Introduction to BC557.
BC557 is a bipolar junction transistor with DC current gain 300. It falls under the category of PNP transistors where one N-doped layer stands between the two P-doped layers. The continuous collector current is 100mA means it can drive load under 100mA. BC557 comes in the TO-92 package and is mainly used for switching and amplification purpose.
Before I bore you to tears, let’s dive in and read the complete introduction to BC557 covering datasheet, pinout, working principle, power ratings, physical dimensions, and applications.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Flame Sensor Arduino Interfacing. Flame sensor is an electronic device which is capable of sensing/detection of fire or a high temperature zone. It gives an indication through an LED attached at its top, just after sensing the fire. These type of sensors are usually used for short ranges. They are able to detect the fire up to 3 feet. Flame sensors is the most common device available in the market these days due to its good results and cost efficiency. You should also have a look at Flame Sensor Library for Proteus.
Flame sensors are available in the market in two types one having three pins and the other having four pins ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explain you about Introduction to LM386. Its a power amplifier specially designed for low voltage consuming applications. The gain of LM 386 is set around 20 internally. But the gain could be increased due to the insertion of external resistor and capacitor between the pin number 1 and 8. The gain could increase to any value from 20 to 200.
The LM-386 inputs are ground referenced. The output are biased to the half of the input voltage levels automatically. When LM 386 operates on 6V, its quiescent power drain is around 24mW. This property of LM-386 makes it ideal for the battery operation. Its major features include battery operation, minimum external p ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new project in which we are gonna do Arduino Bluetooth communication. The Bluetooth module I have used for this project is HC-05, which is a serial Bluetooth module. We can quite easily perform the Bluetooth communication with this module using Arduino board. I have worked on many projects in which I have to send the data from sensors to my computer via Bluetooth. So, in such projects I normally use this Bluetooth module which is connected with the sensors and then Arduino gets the data from these sensors and then send this data to computer via Bluetooth module. In this project, I have used Arduino board but you can use PIC Microcontroller or 8051 Mic ...
Hi Guys! I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to MJE13005.
The MJE13005 is a high speed and high voltage power transistor that belongs to the NPN transistor family. This device can support load up to 4A and the emitter-base voltage is 9V which is the voltage required to bias the device and start the transistor action.
I suggest you read this post all the way through as I’ll detail the complete Introduction to MJE13005 covering datasheet, pinout, features, and applications.
Let’s get started.

Hello friends, Hope you all are fine and having fun with your lives. In today's post, I am going to show How to display a Scrolling Text on LED Matrix 8x8 using Arduino in Proteus ISIS. We all know about LED Matrix but if you don't know then google it. :P LED Matrix is used to display long messages, the best thing about LED Matrix is you can combine then in serial way and can make it of any size you want. Like in this post I have combined 8 LED matrices and then displayed my message on them. I have given all the details here but as you can see we have done a great effort in designing this simulation so I haven't posted it free but have placed a very small amount of $20 on it and you can buy it quite easily from our shop by cl ...
Hi Guys! Welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to LM2596.LM2596 is a step-down voltage regulator, also known as a buck converter, mainly used to step down the voltage or to drive load under 3A. It carries remarkable load and line regulation and is available in fixed output voltages including 3.3V, 5V, and 12V. It also comes with a customized output version where you can set the output voltage as per your requirement.
Just stay with me for a little while, as in this post I’ll walk you through the Introduction to LM2596 covering the datasheet, pinout, features, and main applications of this tiny device. Let’s jump right in.

Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the previous tutorial, we built a motion sensor-based security system with an alarm. Additionally, we discovered how to use Twilio to notify the administrator whenever an alarm is triggered. However, in this tutorial, we'll learn how to build a stop motion film system using raspberry pi 4.
What you will make
With a Raspberry Pi, Py, and a pi-camera module to capture images, you can create a stop-motion animated video. In addition, we'll learn about the various kinds of stop motion systems and their advantages and disadvantages.
The possibilities are endless when it comes to using LEGO to create animations!

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on 2 Relay Module Interfacing with Arduino. First of all I would like to explain you that what is relay and how to use it and then we will move forward towards 2 relay module interfacing with Arduino. I have already controlled relay with 555 timers. 2 relay module consists of two relays. Relay is basically an electronic device or a switch which is used to open and close the circuits electronically.
A relay controls an electric circuit by opening and closing contacts in another circuit. When the relay contact is normally open (NO), there will be an open connection when the relay is not energized. When the relay contact is norm ...
