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 ...

A timer is a simple counter! The input clock of microcontroller and operation of the timer is independent of the program execution.All the Atmel microcontrollers have Timers as an inbuilt peripheral.

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), ...

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 ...

The 8051 is alive and well. Cygnal Integrated Products has crammed a 25-MHz 8051 core, 8 kbytes of flash, and 256 bytes of data RAM into a tiny 11-pin, 3- by 3-mm (9 mm2) micro-lead package (MLP).

8-bit microcontrollers are here to stay despite the rise of 32-bit microcontrollers. Renesas introduced the RL78/G15 entry-level 8-bit microcontroller in a tiny 3x3mm package at the beginning of the ...
