Object counter using 8051 microcontroller.
This article is about a simple object counter/visitor counter using 8051 microcontroller . AT89S51 belonging to the 8051 family is the microcontroller used here. This circuit can count the number of objects passing across a line , number of persons passing through a gate/door and so on. The can be simply divided into two sections i.e. the sensor section and the display section.

Sensor.

The sensor part consists of a ultra bright led (with focus), and LDR, opamp LM324 and the associated passive co ....etc

This network cable tester is designed for testing network cable with CAT 5 connectors, RJ-45. It can be modified to test any 8 conductor cable by replacing the RJ-45 jacks with the mating connectors of the cable to be tested.

The cable tester operation is mostly digital circuitry. The only analog component is the oscillator that uses a NE555 timer as a clock source for the TTL logic. Detailed information for this part can be found here: NE555 Datasheet.

The circuit operates from a single 9V battery. The voltage of the battery is regulated to ....etc

Motion Controlled Robotic Arm Using Flex Sensors



1. INTRODUCTION

Our project deals with controlling a bionic/robotic arm with the help of motion sensing technology by Flex Sensors. The system is basically a master-slave system wherein the master motion sensing glove sits on hosts arm sensing motions of the finger and then using this data to control the servos which control the finger movement of the slave bionic/robotic arm.

How They Work
Flex sensors are anal ....etc

fingerprint based bank locker system ppt

According ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. The present scenario to operate a bank locker is with locks which are having keys. By this we can t say ....etc
