In present times increasing Traffic is adding to the big woes of developing cities. The main roads are packed with vehicular traffic on each and every road or a traffic signal (Intersection Points). One comes across the common problem of traffic jams on almost all Traffic Junctions which is even critical if you go to big cities. A lot of time, energies besides precious fuel is wasted just because of these Traffic Jams on the roads.To solve this problem Traffic Cameras are used over Traffic Intersection points. Traffic Cameras capture the image of vehicles in traffic and sends to MATLAB. Here in this project Traffic Surveillance System is demonstrated by way of how the traffic could be controlled over traffic intersection points from the Traffic Control Room. This is a very effective system for Traffic Surveillance.
DIY: Make Remote Operated Light Fountain
The decorative Light Fountains are readily available in market as gift articles. Here the given project demonstrates how to operate it using TV remote (or any other remote of AC or Music System etc.)To make it Remote Operated it needs to be modified, inside its Internal Circuits and there is also a need to build one Simple Circuit using IR Sensor to sense IR Remote Signal. For your convenience kindly follow step by step process of how to do this with the help of given images.
How Video is Displayed on the Screen
Video is basically data; rather we can term it more aptly as a signal. The signal can be transmitted as analog or digital signal/data; but the thing which remains in the background is that what makes this signal so special. Let us look at this that “how video is displayed on a screen”. First we…
An introduction to ultrasonic sensors
Ultrasonic sensors have been a popular method for distance measurement and object detection for many years. Their basic operating principle works by measuring the amount of time it takes for their emitted ultrasonic pulse of sound to bounce off an object and return, hence the name ultrasonic sensor. With the market for autonomous robots, vehicles,…
Basic Electronics 16 – Supercapacitors
In the previous tutorials, we discussed working with a capacitor, characteristics of a capacitor, various types of capacitors, and selecting a capacitor for a given circuit. As we have learned, typical commercial capacitors have their capacitance in Picofarad, Nanofarad or Microfarad range. The maximum capacitance that these capacitors can provide is 1 Farad. If the…
Getting started with FPGAs
The FPGA is one of the technologies which let an embedded engineer access hardware design of an embedded system. Its greatest advantages include multi-threading, real-time processing, wide scope for custom ASIC design (within available logic blocks on the FPGA chip), reusability and single chip solution. It is highly recommended to get hands dirty on an FPGA board after some work on microcontrollers. After all, hardware design is just another essential twin to software design in embedded engineering discipline.
How to configure Scratch GPIO- (Part 1/12)
Scratch is a programming tool for creating embedded games,stories and animations without using any written codings, rather using visually organized syntax which is in blocks with a drag-and-drop interface. One can use these blocks according to one’s requirement, scratch’s control of hardware is not only limited to the external inputs such as the keyboard and mouse.This article explains how to configure Scratch to extend its power to access GPIO(General Purpose Input and Output) of the Raspberry Pi.
How to Connect Raspberry Pi to WiFi- (Part 3/12)
This article is to make the procedure of setting up the WiFi. The Raspberry Pi is connected to Windows PC through Ethernet cable and the GUI is obtained using a VNC server. Although Raspberry Pi Model B comes with 100Mbps wired Ethernet, it is also essential to connect WiFi.The best arrangement is to purchase a cheap USB WiFi connector and utilize one of the USB ports to get to our WiFi home router. Setting up a Raspberry Pi utilizes the Raspbian OS to get to your remote system is simple – This article will guide you through the procedure.
Basics of Audio Amplifier – 1/9
Audio is one of the most common media. Here, It refers to the representation of sound which can be perceived by humans. Audio and Video are the essential component of any electronic media. The electronics can be used to receive audio signals (via microphone), record audio in some storage, transmit audio (through wired or wireless communication channels) and reproduce audio signals (via speakers). The audio can be represented and transmitted as either analog signals or digital signals. In this series, analog audio signals are the concern. The audio signals have a frequency range of 20 Hz to 20,000 Hz.
Introduction to LUFA
Universal Serial Bus (USB) is now a common and vast framework for serial communication. The interface not only allows serial communication, it also works as electronic power supply. The popular AVR microcontrollers fortunately have the USB interface feature and can be programmed to build USB devices. The USB specification is long and intimidating. It can be a daunting task to write a device specific USB driver.
DC motor speed control using the Bluetooth-based Android app
This project is somewhat different than the previous ones we’ve covered on DC motor control. So far, the articles have included insight on controlling a DC motor speed by using: Arduino An 8051 microcontroller An AVR / PIC / ARM microcontroller A remote SMS Bluetooth This time, we’ll be covering DC motor speed control via…
What is the Z-Wave protocol?
Smart homes need wireless connectivity, and Z-wave has emerged as the ultimate solution for home automation. The Z-wave protocol is a wireless, radio frequency protocol designed primarily for smart home networks. All the existing wireless communication protocols had one or the other problem. Bluetooth and Zigbee often shortfall of range while Wi-Fi poses its own…
