Firstly we will understand what is seven segment and how it works. Then we will learn the interfacing part in more easier way. The seven segments displays are the oldest yet one of the efficient types of display used in embedded applications. This display has nothing more than 8 LED inside it. Each of the seven LEDs is called a segment because when illuminated the segment forms part of a numerical digit (both Decimal and Hex) to be displayed and sometimes an additional 8th L

In last lesson we learned the importance and some features of Arduino Uno. Now we will discuss how we can use this Arduino Uno for different applications. To use the Arduino Uno as per the user commands, it need to be programed using an Arduino IDE software. You can download this software here. This is the link for Arduino official website. You just need to click on downloads then scroll down you will find Window installer option(it's size is around 85MB). After this click on

A development board is basically a printed circuit board with circuitry and hardware on-board to facilitate experimentation with certain microcontrollers. These boards can save you from a lot of repetitive tasks. These development boards can be used in multiple projects, so it is a one-time investment. Typically, components of a development board include: 1. Power circuit (typically, set up to run from a 9V/12V power supply) 2. Programming interface 3. Basic input circuitry,

About Raspberry Pi : Raspberry Pi is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video to making spreadsheets, word-processing, and playing games. It is a small single-board computer, by connecting peripherals like a Keyboard, mouse, and display to the R

Internet of Things In this series of tutorials, you are going to learn all about the Internet of Things and how to use it to solve real-time day-to-day problems. We assure you after going through all the lessons of the Internet of Things(IoT) you will be comfortable with the term IoT and having a good understanding. So, let's get started without wasting the time. Lesson- 01: Introduction to Raspberry Pi Lesson- 02: Introduction to IoT Development Boards. Lesson- 03: Introduct

Electronics domain involves a lot of skills starting from basic device and circuit simulations, to PCB design, micro controllers and a complete IoT system implementation. Hence, for any beginner it is necessary to explore the open source tools and software that can be utilised for skill development, concept building and learning with hands on experience. Octave : For mathematical equations, Matlab basics, numerical computation, plotting graphs, matrices, linear and non linear

Universal Asynchronous Reciever-Transmitter Introduction The transmitter converts parallel data from a controlling device like a CPU into serial form, transmits it in serial to the receiving UART, which then converts the serial data back into parallel data for the receiving device. Data flows from the Tx pin of the transmitter to the Rx pin of the receiver hence only two wires are needed to transmit data. UART transmit data asynchronously, which means there is no clock signal

CMOS Transmission Gate Introduction In electronics, pass transistor logic (PTL) describes several logic families used in the design of integrated circuits. It reduces the count of transistors used to make different logic gates, by eliminating redundant transistors. Transistors are used as switches to pass logic levels between nodes of a circuit, instead of as switches connected directly to supply voltages. This reduces the number of active devices, but has the disadvantage th

Differential Amplifier All operational amplifiers (op-amps) are differential amplifiers because of their input configuration. When the first voltage signal is connected to the input terminal and another voltage signal is connected onto the opposite input terminal then the resultant output voltage is proportional to the difference between the two input voltage signals of V1 and V2. The output voltage can be solved by connecting each i/p intern to 0v ground using a superpositi

Operational Amplifiers Topics to be covered Operational Amplifier Characteristics of Operational Amplifier Op-amp Parameter and Idealized Characteristics. OPAMP applications Operational Amplifier Operational Amplifier Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical operations such as add, subtract, integration, and

The current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being "copied" can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well. Or it can consist of a current-controlled current source (CCC

Introduction to CMOS Stands for "Complementary Metal Oxide Semiconductor." It is a technology used to produce integrated circuits. CMOS circuits are found in several types of electronic components, including microprocessors, batteries, and digital camera image sensors. The "MOS" in CMOS refers to the transistors in a CMOS component, called MOSFETs (metal-oxide semiconductor field-effect transistors). The "metal" part of the name is a bit misleading, as modern MOSFETs often u
