ABSTRACT: The fundamental goal of this project is to develop a fastest finger-first quick buzzer system that can be utilized to perceive the member who presses the signal fastest and first among all in a group of peoples in a test quiz competition by the test computation sensor (D-flip-flounder). This circuit incorporates 8 numbers of […]
ABSTRACT: The project is designed as a security system based on photo sensing course of action. It utilizes a 14-stage ripple carry binary counter to sense the light intensity through LDR. The output drives a buzzer and a relay for important activity. This idea is very valuable to detect burgulars from banks, malls, jewellary stores […]
ABSTRACT: The project is designed to develop a time delay based switch to control any load. A 555 timer is utilized as a part of monostable mode to drive a relay to switch ON/OFF a load for fixed time duration. A time delay based relay is a relay that stays on for a specific period of […]
ABSTRACT: The project is designed to develop a touch sensitive switch to control any load. A 555 timer is utilized as a part of monostable mode to drive a transfer to switch ON a load for fixed time duration. The 555 timer is triggered by a touch plate connected with its trigger pin. The output […]
ABSTRACT: The project is designed to generate an alarm signal in case of breaking of a wire in loop. The project utilizes a buzzer to alert the client. This framework is based after utilizing a 555 timer in astable mode. A transistor is utilized to trigger the timer, at whenever there is a break in […]
ABSTRACT: The solar energy is converted to electrical energy by photograph voltaic cells. This energy is stored in batteries during day time for using the same during night time. This project manages a controlled charging mechanism which over charge, deep discharge and under voltage of the battery. In this project a solar pannel is utilized […]
ABSTRACT: The project is designed to monitor the counting the operations in industries. For instance, products moving on a conveyor belt are counted by IR interruption concept and displayed on a seven segment display. There are two pair sensors, each kept at certain distance from the other. One pair of sensor comprises of a transmitter and […]
ABSTRACT: The project is designed to construct an approaching telephone ring flasher appropriate for noisy environment conditions. A phone line is connected through an opto isolator to drive a relay at whatever telephone ring is identified by the circuit. The lamp flashes at whenever there is an incomming call. This framework is highly helpful in […]
ABSTRACT: The project is designed to develop a temperature control framework utilizing a thermistor. It is useful to keep up a constant temperature of an encased area. At whatever temperature increments beyond certain value, a lamp (demonstrating a cooler) is switched on to bring the temperature to normal value. As switching ON of load is […]
ABSTRACT: The goal of this project is to develop a rhythm following flash led’s which blinks following the rhythm of the music. The light which glows as according the rhythm of the music is fascinating to watch. Researchers established that the mus lights speedup the brain waves that devlops the higher concentration levels. This project is executed […]
