Review: Ultrasonic Sensor Based Distance Measuring System

A mini project for beginner to measure the distance between sensor and an object without using measuring scale. It can be constructed using bread-board, Arduino Board and easily available components from electronics labs or Shops such as an Ultrasonic Distance Measuring Sensor Module, wires etc.

Review: Arduino Based Voice Controlled Automation System

A mini project for beginner to make LEDs ON/OFF by voice command given at Bluetooth enabled Mobile Phone end Wirelessly. It can be constructed using bread-board, Arduino Board and easily available components from electronics labs or Shops such as a Bluetooth Module, and Bluetooth Enabled Mobile Phone at user end [with voice search facility] etc.

Review: Arduino Based Wireless RGB LED control System

A mini project for beginner to make RGB LEDs control as change command is given at Bluetooth enabled Mobile Phone Wirelessly via Application program. It can be constructed using bread-board, Arduino Board and easily available components from electronics labs or Shops such as a Bluetooth Module, and Bluetooth Enabled Mobile Phone at user end [with Color Change App installed] etc.

Review: Smoke Detector System

 

Title: Smoke/Gas Detector and Alarm System

Usually all premises or habitat needs Smoke Detector as they are fire hazardous places [as they contain power supply or fire] and easily vulnerable to such catastrophic. Smoke Detector indicates the presence of smoke in early stage, which may leads to fire hazards [i.e., assumed that smoke comes before any fire accident].

Review: Microphone Preamplifier

While extracting weak signals, with compromising the intrinsic signal to noise ratio (SNR), from microphones, audio sources, and other sound detectors and fed to Power Amplifiers for further processing some small amplification is needed. Such one stage is called Preamplifier stage.

Review: Android Based Home Automation System

Bluetooth is the buzz word, while designing any automation system for study purpose. Automation of Home/Work place is common using short range communication technology, called Bluetooth. This is because physically challenged or elderly/sick people cannot access all devices/gadgets present in the home/work place. The Bluetooth enabled Android Mobile Phone can be used as remote control and control all fan, light, water heater, garage door etc. by sitting at one place.

Review: GSM Based SMS Controlled Robot

Robots are used to do repetitive tasks as per programmed instructions or remotely sent commands. One such robot is remotely controlled moving vehicle, used to detect dangerous objects or task which man or animal cannot do safely.

Review: Embedded Based Contactless Tachometer

The ‘Embedded Based Contactless Tachometer’ as name implies used to measure revolutions per minute of any rotating dc motor.

The Speed of an electric motor is measured as revolutions per second using Tachometer. The Tachometer is available in Analog/Digital, or Contact/Contactless types.

Review: Metal Detector Robot

The ‘Embedded Based Metal Detector Robotic Vehicle’ is used to detect metal and ores beneath the soil remotely.

With embedded system, robotics is usually one of the closed linked topic as circuit, power requirement, portability minimizes to its limit.

Metal detection is done at specified location, as at entry point of any premises, stadium, railway station, bus stands. In such cases no moving robot is needed.

Review: RFID Based Attendance System

The ‘Embedded Based Attendance System’ as name implies used to take attendance by electronics means.

The attendance system usually takes on attendance register or paper. That is transfer/fed to digital database or master book. By this method paper is wasted as it is a limited natural resource. Instead of these two steps: intended system is designed to carry out in simpler form.

Review: Smart Street Light System

The ‘Embedded Based Smart Street Light System’ as name implies used with street lights or in-door light systems to reduce power waste and maintain over-all portability.

Review: Temperature Controlled Fan System

 

The intended system/project ‘Temperature Controlled Fan System’ is generally used in electronic devices, project cabinets, with kits which produces unwanted heat due to varying load conditions during their normal operation.
