This project implements a frequency counter using an AVR microcontroller, a 16-bit timer, and external interrupts. It allows measuring the frequency of an input square wave signal accurately. Connect ...

The Frequency Counter is a project designed to count the frequency of an unknown signal using the Microcontroller 8051. It measures the number of cycles of a signal that occur per second and displays ...

In this paper the authors give a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been ...

The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate ...

The main intention of this circuit is to build a system wherein the number of persons entering or leaving a room has to be displayed on a screen. This is one of the best and very useful circuits in ...

In life and embedded systems timing is everything. Give [Frank’s] web-based timer calculator a try. Set your system clock resolution (in hertz making sure you account for any system clock divider), ...

Abstract: Teaching/learning microcontrollers in the laboratory has been traditionally carried out using general purpose simulators and/or evaluation boards. In-circuit emulators are not widely used ...
