This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless server that’s acting up or if you are building a minicomputer out of a WRT, or if …

The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we build a nice clock which gets time and date via …
LCDs are often used in microcontroller projects. Most used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. Some time ago I ordered a Nokia 6100 LCD including breakout board from …
I spent part of an afternoon developing a hardware RSS reader (most of my time was spent on the python side of things). It’s pretty simple and uses an AVR microcontroller connected to a computer via a serial cable. Hardware I am using the Dragon Rider 500 as a development board. This provides all of the hardware …
I. Introduction Simply write; your computer will undersand! We have designed and implemented a Handwriting Recognition System using a touch screen from a Palm Pilot m125, a black and white TV and a Mega32 microcontroller. Unfortunately, due to the lack of specifications regarding the built-in LCD on the Palm Pilot, we were unable to reverse …

Introduction Objective The goal of this project is to design a useful and fully functional real-world product that efficiently translates the movement of the fingers into the American Sign Language. Background The American Sign Language (ASL) is a visual language based on hand gestures. It has been well-developed by the deaf community over the past …
Introduction The clock is one of the oldest inventions in human history and has been used for centuries as in instrument for measuring time. There are many ways to implement this ancient technology by simple and practical methods. However, simplicity and practicality were not among the goals of this project. Instead, the project is intended …

A microcontroller is a device which has an inbuilt processor surrounded by few dedicated hardware modules. Once the microcontroller initializes them they start operating on their own. In case of an ADC it will do the sampling and digital to analog conversion all by itself and keep the converted data in its buffer so that …
In almost all the microcontroller codes the peripheral initialization functions like uart initialization, spi initialization are written along with the different application codes. These initialization functions are actually repetitions of the original initialization functions. The same is the case with the external hardware initialization like LCD initialization, GSM modem initialization etc. Suppose the case in which …
