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… |

555 Timer Monostable Multivibrator Circuit Monostable multivibrator (MMV) mode of 555 timer IC is also called Single shot mode. As the name indicates, only one state is stable and the other one is called unstable or quasi stable state. 555 timer IC remains in Stable state until the external triggering is applied. An external triggering is required for transition from Stable to unstable state. 555 IC automatically… |

Toggle Switch Toggle switch is used to toggle the output between two devices. Means when one device is ON, second device remains OFF and when second device is OFF, first device becomes ON. This toggle of output can be controlled using a PUSH button switch, so you can control two devices using one button. Further you can interface two Relays in place of LEDs to control the two AC… |

Digital Dice Circuit Dice can be used to play several games, such as Snakes and Ladders, Ludo, etc. Generally, dice are made of wood or plastic, which gets distorted over time and becomes biased. A digital dice circuit is an alternative to the traditional dice; it can’t be biased or distorted, and it acts so fast that nobody would be able to cheat. This guide will explain how to build a digital dice circuit… |

Clap Switch Clap switch is an interesting hobby circuit that turns on the lights with a clap sound. Although its name is “Clap switch”, it can be turned ON by any sound of approximately the same pitch as a clap. The main component of this clap switch circuit is the Electric Condenser Mic, which has been used as a sound sensor. The Condenser Mic basically converts sound energy into… |
