This programmer is based on USBasp design and connects to your computer's USB port. Not only is it quite compact, but the design is really elegent. The USB interface is achieved by using an atmega processor and the rest is done in firmware.8051 USB programmer supports 7 Atmel 8051 microcontrollers. It is a reliable tool for fast programming of 8051 devices.

Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and at the same time, act to lower voltage levels within circuits. In electronic circuits resistors are used to limit current flow, to adjust signal levels, bias active elements, terminate transmission lines among other uses.

Irrigation using fresh water resources is a task of high importance in Agriculture.Efficient water management system is essential because of the large quantity of fresh water consumed for this purpose. Optimal usage of fresh water resources has been achieved by means of Automation. Determining when and where to irrigate and how much water to use by  soil moisture monitoring at particular intervals of time will help in making an efficient automated irrigating system. The project automates the whole process and removes the need for workmanship.

Intelligent Vehicle tracking systems (IVTS) are used for the purpose of tracking and navigation of vehicles. The paper describes the implementation of Global positioning systems (GPS) in IVTS systems. Further a critical GPS based low cost IVTS architecture has been described. The first part of the paper describes the need and the basic architecture of a general GPS based IVTS system.The GPS based low cost intelligent vehicle tracking system can be successfully designed and applied in the urban environment of a developing country like India. This if implemented in a well planned manner will bring significant revolutionary enhancement in the I n d ia n transportation industry.
