We're glad you could join us for another lesson in our comprehensive Raspberry Pi programming guide. I will show you how to install and connect the RFID card chip to your Raspberry Pi through step-by-step instructions.
Modern security systems would only be complete using radio frequency (RFID) devices. To control who can enter a facility or which rooms they can access, RFID chips and card readers are employed. The RFID card's unique identification number can be read wirelessly with a wall-mounted RFID reader. A door will only unlock and allow entry if the RFID card's unique identification number matches a list of approved cards.
It's fun to tinker with this circuit, and it may be used in many other applications, from opening locks to taking a ...
Hello Guys! Hope you’re well today. Happy to see you around. I welcome you on board. In this post today, I’ll detail the Introduction to 1n5822.
The 1n5822 is a Schottky diode that comes with a low forward drop voltage around 0.525V which means it needs 0.525 voltage to conduct the current in forward biased direction. It supports a load under 3A and is an ideal pick for switching applications with low current ratings. And the 40V is the maximum repetitive peak reverse voltage Vrrm of this tiny device.
Just bear with me for just 2-min as I’ll be discussing the datasheet, Pinout, specifications, and applications of this tiny little device.
Let’s get started.
Introduction to 1n5822
1n5822 is a Schottky diode, also known as a hot-carrier diode, ...
Hi Friends! Hope you’re well today. Happy to see you around. In this post, I’ll detail the Introduction to Arduino UNO REV3.

Know that Arduino UNO REV3 is an advanced version of Arduino UNO. The new version includes four solder pads JP2 attached with the pins PB4 to PB7 of the USB ATmega.
Uno stands for one in Italian and this name was picked for the release of Arduino ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to Arduino Nano 33 BLE.
Arduino Nano 33 BLE is an advanced version of Arduino Nano board that is based on a robust and powerful processor the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU. It comes with a crystal oscillator frequency of around 64MHz. It features 32 times bigger program memory than the Arduino Uno board, helping you store programs with much larger memory. With this device, you can produce a lot more variable as it comes with RAM that is 128 times bigger than the RAM of Arduino Uno.
Before you move further, I recommend you read this article on the Introduction to Arduino Nano which we have publish ...
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 ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP121. The TIP121 is an NPN Darlington pair transistor. It exists in a TO-220 casing and creates for normal amplification and less moving speed switching submissions. Like other transistors, it has three pinouts emitter, base, and collector. The central part this transistor which is known as the base is thinner in size and other two emitters and collector has larger areas.
Transistors are playing an important rule in our electronic circuits and industries. Every electronic device like mobile, radio, LCD, etc all these have different types of transistors. Like other transistors, TIP121 is performing an important rule in electron ...
Hello friends, today I am posting a very basic tutorial on what is Arduino ??? In this tutorial I am gonna explain the basics of Arduino for the beginners. I am writing this tutorial because I got a lot of requests from the engineers in which they ask questions like what is Arduino ? What's the difference between Arduino and PIC? How to use Arduino? etc etc. So I thought of writing this topic. It's a very basic tutorial so if you are already familiar with this board and know the answer of this simple question What is Arduino ??? then you can skip this tutorial but again you must read it once, may be you get something out of it. :)
I have posted a tutorial on Arduino Projects, in which I gave all the links of Arduino projects and tutorials posted o ...
Buy This Project
Hello everyone, I hope you all are doing great. Today, I am going to share a new Project which is Smart Blind Stick using Arduino in Proteus ISIS. I have designed its complete Simulation which I am gonna share today. We have designed this Proteus simulation off Smart Blind Stick after quite a lot of effort that's why its not free. We have placed a small amount on it and you can buy it from our shop via PayPal. You need to click on above button in order to buy this project's code and Simulation. If you have any problem in understanding this project, then you can ask in comments and I will try my best to resolve your issues.
Smart Blind Stick project is designed quite a lot in engineering universities. That's why, I thought of sha ...

Hi Guys! Hope you’re well today. In today's tutorial, we will have a look at the 2SC1345 NPN Transistor. We will also discuss 2SC1345 Datasheet, Pinout, Power Ratings, Equivalents & Applications. As this is an NPN transistor, the conductivity is mainly carried out by electrons as the major charge carriers. 2SC1345 is mainly used for switching and amplification purposes.Let's first recall NPN transistors: NPN transistor comes with 3 terminals, named:
Emitter
Collector
Base
If the voltage at the base terminal is above 0.7V, the NPN transistor gets forward biased & starts conducting i.e. current will flow from the Collector to Emitter terminal. If the Base voltage is less than 0.7V, it remains reverse-biased.So now let’s get started with the 2SC1345 NPN Transistor.
2SC134 ...
