This project builds upon the PIC/TI83+ interface developed by ThomasHenry (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 was …
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. Below is a list of components which …
In this project, which is designed using DALLAS DS89C430 microcontroller (in simulation AT89C51RC2) circuit and a marching band, calculated on the length of the body, the LCD display was performed. Circuit consists of three… Electronics Projects, Calculation of Body Length with 8051 and DS89C430 “8051 example, avr project, keil example, microcontroller projects, “ In this project, which is designed …

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 …

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 …
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: …
INTRODUCTION: Our project is a wireless communication link which interfaces to the serial ports on the TI-83 and TI-84 calculators. SUMMARY: Our group created a wireless communication system for the widely popular TI 83/84 calculators. The system interfaces to each calculator through their 2.5mm serial ports. Using an instant messaging chat program written in TI …
Introduction We designed a device that measures and graphs various aspects of AC power and acts as a computer-controlled remote switch. With the recent push for green energy and environmental friendliness, more and more people are concerned about their personal daily power usage. We developed a microcontroller-based device to measure AC power. The user will …
