LED Strobe Light Circuit In this project let us develop an LED Strobe light circuit using the popular 555 timer IC. A strobe light or a stroboscopic lamp is one which can produce regular flashes of light. We are designing this circuit using a 555 timer for setting the delay between each flash and a high power LED light as the source of light. At the end of this project we will learn how to use 555… |

Arduino Timer Tutorial The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support the design and use of simple electronics, working with Arduino timer functions without requiring deep programming expertise. This simplicity led to fast adoption by electronic… |

Music Operated Dancing LEDs You must have seen the Disco Lights or DJ lights, which Turn ON and OFF according to the beats of the music. These lights glow according to the length and pitch (volume) of music beats, basically these are designed to pick the high intensity sound like Bass sound. So these lights follow the high pitch beats in music like drum beats, and Turn ON and OFF according to music… |

8x8 LED Matrix using Arduino In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name LED matrix.
These matrixes can be made by… |
