WATER TANK LEVEL CONTROLLER USING WATER LEVEL SENSOR

Abstract In this project, IC and water level sensor are used to control the water level in a water tank. This project switches on the motor pump when water in the overhead tank falls below the lowest level and turns it off when the tank is full. It is to replace the traditional way that use tank ball. The water level is sensed by two water sensor to operate the switches for controlling the pump motor. ...

Fastest Finger First for Buzzer Rounds in Quiz Competitions

Abstract In the buzzer round of quiz contests, the question is thrown open to all the teams. The person who knows the answer hits the buzzer first and then answers the question. Some times two or more players hit the buzzer almost simultaneously and it is very difficult to detect which of them has pressed the buzzer first. In television shows, where the whole event is recorded, the actions are replayed ...

DTMF Based Human less Boat Control For Oceanic Research Applications

Abstract This project is a prototype boat that can travel in water. The direction of the robot can be controlled by DTMF. This can be moved forward, backward direction. Also this robot can take sharp turnings towards left and right directions using DC Motors. This project uses AT89S52 MCU as its controller. This project uses DTMF technology for controlling Robot in a way such that near the controlling ...

DIRECTIONAL COUNTER

Abstract Counters with directional detection are useful for counting of objects moving along a predefined path. These may find application as visitor counters and also for counting of objects in a given direction and ignoring those moving in the reverse direction. Here we present a simple circuit that counts the number of persons or the objects entering the premises ignoring those exiting or leaving ...

DC Motor Speed & Direction Control using ARM(ARM7TDMI) processor based microcontroller(LPC2148)

Abstract This project is designed to control the speed and direction of a DC motor using ARM based microcontroller. H-Bridge technique is used to control the direction and PWM technique is used for speed control. The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/512 kilobytes (kB) of embedded high speed flash memory. A 128-bit ...

Controlling Electrical Appliances through TV Remote

Abstract This is an interesting project built with an IR sensor and a decade counter. By using this project, one can control his lights / fans / AC / any electrical appliance with a TV Remote. CD4017 is a CMOS Decade counter. It can detect a clock pulse and the BCD out put will be incremented by one for each CLK pulse. If we observe the BCD numbers, the LSB (Least Significant Bit) of BCD complemented ...

AUTOMATIC WASH BASIN MIRROR LAMP CONTROLLER

Abstract Generally, in restaurants, auditoria and even homes, many a times  we forget to switch off the wash basin mirror lamp after use. So to rectify this problem we have designed a project named “Automatic wash basin mirror lamp controller”. This project automatically switches on the wash basin mirror lamp whenever a person stands in front of it and switch off the same after you move away from ...
