Generally, one can see the digital displays which display the score when buttons are pressed on score boards. The main heart of this score board is 2 digits up/down counter circuit. The 2 digits are displayed on two 7 segment displays. This article describes 2 digit up/down counter circuit. 2 Digit Up/Down Counter Circuit Principle: …
Power Supply: It can be defined as a device that supplies electrical energy to one or more electric loads. The term is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy. …
In this tutorial we are going to discuss and design a circuit for measuring distance. This circuit is developed by interfacing ultrasonic sensor“HC-SR04” with AVR microcontroller. This sensor uses a technique called “ECHO” which is something you get when sound reflects back after striking with a surface. We know that sound vibrations can not penetrate through …

When deciding what type of connectivity your next project will use cellular tends to be considered an expensive alternative to WiFi or Bluetooth. This tutorial is meant to break that way of thinking and show how easy and inexpensive cellular could be with the right provider and tools. …
This project builds upon the PIC/TI83+ interface developed by Thomas Henry (see Nuts & Volts August 2013 – A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project possible. When I recently re-discovered that article, I imagined re-creating the only calculator that …

Generate sound or output analog voltages with an Arduino. This Instructable will show you how to set up a really basic digital to analog converter so you can start generating analog waves of all shapes and sizes from a few digital pins on an Arduino. (This article is a companion to another Instructable I’ve written …
