White light on light-emitting diodes (LED) as a substitute for HID lamps in street lighting system, to include the dimming function. 8051 microcontroller family is used to control the intensity, developing a pulse-width modulated signals that triggers the MOSFET for switching LEDs accordingly to achieve the desired operation.

In this system, mainly covering roads is carried out through the discharge lamps (HID), the energy of which consumption is high. Its intensity may not be managed in accordance with the requirement there is therefore a nee ....etc

pic16f877a code for heart rate measurement

Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. This project describes a technique of measuring the heart rate through a fingertip using a PIC microcontroller. While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can ....etc

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
Gas detectors can be used to detect combustible, flammab ....etc
