Battery Tester Project Using LM3914 IC
This objective of this project is to design and build a battery tester that is able to test various types of dry cell and rechargable battery with a voltage of less than 2V. Configured as a bar graph battery level indicator, the LM3914 IC from National Semiconductor senses the voltage levels of the battery under test and drives the 10 LEDs to ON or OFF based on the voltage that is detected. The current driving the LEDs is regulated by using the external resistor R1 and hence limiting resistors are not req ....etc

Simple Component and Continuity Tester
This simple project may be used for testing components, as well as checking circuit board tracks, wires and connections for continuity. a small current is passed through the item being tested
and the LED will light brightly, dimly or not at all according to the resistance of the item.

indication:LED bright means the resistance is low, less than about 1kW
-LED dim:-resistance is medium, a few kW
-LED off:-resistance is high above 10k

Parts Required:
resistor: 390W,red LED 5mm diameter, cr ....etc

A Brushless Servomotor has been developed by using interdisciplinary mechatronics engineering. A mechanical switching device (commutator) is replaced by electronic circuits and controllers resulting in maintenance free and high performance servo drive. The brushless servomotor is an ac motor, in all respects and is in fact called the ac servomotor. Combined with a dedicated control device, the performance of the brushless servomotor is found to be equal to the performance of the high performance dc servo motor. In dc motor when the current fl ....etc

Pulse Width Modulation is widely used in power electronics as a controller in power conversion and motion control. Among different types of modulating modes the Sinusoidal Pulse Width Modulation (SPWM) and Space Vector PWM are two common strategies in adjustable speed drive system. The Pulse width of SPWM varies with the Sine wave so as to restrain the lower order harmonics with easy control and large D C utilization. With successively improving reliability and performance of digital controllers, the digital control techniques have predominated ....etc

Introduction to Servomotor Programming

Welcome to Servo Programming
In the previous chapters, we’ve done some cool things, but we’ve essentially treated our robot as a desktop
computer. Now we are ready to attach the BX-24 to a robot body and make it mobile with the use of
servomotors. In this chapter, you will learn what servos are, how they operate, and how modified servos can be
used as drive motors for the Robodyssey Mouse.
This chapter covers many important topics, so read it slowly and tho ....etc

Abstract

A method and apparatus for verifying an integrated circuit device test for testing an integrated circuit device on an automated tester is presented. An integrated circuit device simulator simulates a flawed integrated circuit device that models one or more known flaws, or physical defects, in an assumed good integrated circuit device design. A tester simulator simulates the integrated circuit device test which sends stimuli to, and receives responses from, the simulated flawed integrated circuit device.

A test analyzer then dete ....etc
