7 Segment Display Pinout | Working Understanding of 7 Segment Display

A seven-segment display is commonly used in electronic display device for decimal numbers from 0 to 9 and in some cases, basic characters. Use of light emitting diodes (LEDs) in seven...

Remote Access to Raspberry Pi

Raspberry Pi is an excellent platform to learn programming and interfacing of a computer with the real world. But it is always annoying to move to a completely different setup to...

Simple FM Receiver

Frequency modulation is used in radio broadcast in the 88-108MHz VHF band. This bandwidth range is marked as FM on the band scales of radio receivers, and the devices that are...

Motion Detector Using NE555 Timer

This circuit is based on a passive infrared (PIR) sensor, which automatically switches on a device when someone comes close to it. It can be used for detection of theft or...

Electronics Projects: Simple Line-Following Robot

Generally, line follower robot is microcontroller-based. Here we describe a line follower robot without microcontroller for those who are not familiar with microcontrollers. It is a simple project, which can be...

Solar Compass with Oled Display

The solar compass presented here is a navigational tool, which helps in finding directions through the position of sun in the sky as reference. This solar compass is not influenced by...

Arduino Based Programmable Digital Data Display

LCDs are widely used in applications like token-display machines in smalls and supermarkets, order number displays in restaurants and café, and so on. The project presented here demonstrates the working of...

Getting Started With Raspberry Pi

Most computer science students get to learn high-level programming languages and application development but they don’t really understand computers. The fun of controlling the real world with a real computer is...

Voice-Controlled Home Automation System

This project is about controlling home appliances with your voice through an Android app. An Arduino Mega board is used for controlling the relay through which an appliance is switched on/off....

Image Processing Using C++

Digital computers store pictures as strings of binary values. The entire picture is divided into a number of pixels—the smallest elements of the picture. The colour and intensity values of each...
