received data is then sent to the receiver PC serially. The RS-232 cable (DB-9 connector in this case) is used to coordinate the serial communication between the computer and the microcontroller. The RS232 standard is not TTL compatible‚ but the 8051 has two pins‚ that are used specifically for transferring (P3.1) and receiving data (P3.0) serially which are TTL compatible; therefore it requires a line driver such as the MAX232 chip to convert RS232 voltage levels to TTL levels‚ and vice versa

Tachometer Featuring LCD display and automatic DATA hold function By Ibrahim Kamal Last update: 14/7/10 This article describes how to build a contact -less tachometer (device used to count the revolutions per minute of a rotating shaft) using a 8051 microcontroller and a proximity sensor. As the name implies‚ what makes this device special‚ is that it can very accurately measure the rotational speed of a shaft without even touching it. This is very interesting when making direct contact with

8051 Project: Automatic Lighting and Visitor Counter Andrew Herzog Richard Baker December 13‚ 2007 CMPET 211 Executive Summary The objective of the project was to create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project
