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 ...
