Implementation of Serial Port Driver using ARM(ARM7TDMI) processor based microcontroller(LPC2148)

Abstract This project is designed to implement serial port driver by interfacing 16 X 2 character LCD to ARM based microcontroller. Data entry is through PC’s hyper terminal and the received data is displayed on LCD. MAX 232 is used to communicate with the hyper terminal. The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/512 ...

Speed Checker with High Speed Alert System for High-ways

Abstract Over speed is a significant factor in serious road accidents. The statistics or a newspaper always high-lighted with an increasing accidents on road which is a major headache for traffic police and Transport department people to control and Road safety authorities around the world always conduct various awareness programs or campaigns and advertise regarding over speed and  One counter measure ...

Robotic Arm with Base Rotation, Elbow and Wrist Motion with Functional Gripper

Abstract In recent years, the definition of a robot is generally used to mean an unmanned system or automation, as often seen in industrial applications, deep sea planetary probes. Historically speaking, a robot used to be shaped like humans, and referred to as machines and electric systems that were capable of performing similar actions as humans. It is these robots that play active roles in comic ...

Transformer less Solid State Power Supply Design

Abstract There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier circuit. There are also switching power supply solutions, however, in applications that involve providing a DC voltage to only the microcontroller and a few other low-current devices, transformer-based or ...

Wireless Petroleum Level Sensor using RF Communication

Abstract Level sensing from remote place is useful application in many industries. This project is designed to monitor the level of petroleum tank from a remote place. Four Reed Switches are connected to the RF Encoder. These reed switches are placed on the container from outside. This encoded data is transmitted through a RF transmitter module. In the receiver side, the RF receiver module receives ...

High Sensitive Low Power Electronic Ear (Poor Man’s Hearing aid)

Abstract Normally, hearing aid circuits consume battery power continuously once they are switched on. This project is designed to save battery power by switching on the sound amplifier section only when sound is detected. The sensitivity of the detection section and the ‘on’ time duration of the sound amplifier circuit can be set by the user. Also the circuit uses only a single condenser mic for ...

H-Bridge Implementation for DC motor Direction Control

Abstract DC motor control is an essential task in any robotic project. In many applications, DC motor is required to be rotated in clockwise and counter clockwise directions. For this purpose H Bridge is designed. In this project L293D IC is used to drive two DC motors. This IC has 600mA output current capability per channel and 1.2A peak output current (non repetitive) per channel. This is also having ...

Hand Gesture Based Wheel Chair Movement Control for the Disabled

Abstract Robotics has been of interest to mankind for over hundred years. However our perception of robots has been influenced by the media and Hollywood. The vast majority of robots do have several qualities in common. First of all, almost all robots have a movable body. Some only have motorized wheels, and others have dozens of movable segments, typically made of metal or plastic. Like the bones ...
