This small project let you make running leds. For this project you need a attiny2313 microcontroller and 8 leds and 8 resistors. The leds can be programmed so that they show differrent patterns. Hardware The leds are connected to PORTB of the microcontroller via the resistors that limit the current to 20mA. The project can […]
This is a Dot Matrix Scrolling Sign. A Dot Matrix Display has an 5×7 led matrix with 5 columns and 7 rows. The display is controlled by the ATMega328 microcontroller board. The rows are controlled by PORTB of the microcontroller, while PORTD puts the data on the columns to make the characters. The Dot matrix

This tutorial will give you a brief introduction to the concept of colors and how different colors can be produced using RGB LED. The color would be controlled using an ATMega16 microcontroller. RGB LEDs are basically the combination of the 3 LEDs (Red, Green and Blue) fused into a single package. It consists of four

Previously before 10-15 years the majority of electrical lights were either light bulbs (with yellow light) or tube-light sticks (with white light). The major disadvantage of these lighting devices was they consume more electrical energy (in terms of Watt) and gives less luminance (brightness). Light bulb wastes their most of the energy in form of

Now a days LED light bulbs are becoming more and more popular because they have several advantages. Some of their advantages are listed below · Their energy (electrical) consumption is much more less · Their luminance is more · Their intensity can be varied · Their life time is more So if LED lights are

Introduction For our ECE 4760 final project, we designed and implemented a remote controlled persistence-of-vision (POV) display that is able to display multiple patterns based on remote input. The primary components of the display are a rotor and a motor. The rotor is mainly consisted of a row of LEDs and a microcontroller. The microcontroller

Our project implements a touchpad input system which takes user input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but our training system could be easily generalized to include any figure of completely arbitrary shape, including alphanumerics, punctuation, and other symbols. A stylus is used

Introduction Our project records and extracts event-related features from a 36-point relative blood-oxygen concentration sensor array from the surface of the brain. We chose this project because of a combined interest in brain-computer interfaces. In an attempt to balance cost, complexity, and sensor density, we decided to implement a NIRS-inspired system. After collecting data from
