7 Segment Counter using IC 555 and IC 4026 Digital counters are needed everywhere in this digital world, and 7 segment display is one the best component to display the numbers. Counters are needed in object/products counters, digital stopwatches, calculators, timers etc. To use the 7 segment with ease, there is a 7 segment driver IC which is IC CD4026, so we are building 7 segment counter circuit using 4026 IC. … |

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… |

Simple LDR Circuit Here we have explained a dark detector circuit by using 555 timer IC and a LDR (Light Dependent Resistor) which senses the light in surroundings and if it does not find the light, it triggers the IC and glows an LED attached with the circuit. In place of LED we can also use a buzzer or speaker to use it as dark detector alarm. The concept of this LDR circuit is quite simple… |

Simple Touch Switch Circuit using 555 Timer IC This simple Touch Switch is developed by using 555 timer IC operated as a MONOSTABLE vibrator. Here the stable stage is LOW, so the timer outputs low after the trigger is removed. Basically in this circuit we will have a LED which turns ON when we touch a pin of timer. The LED will be ON for the time during which the trigger is present. Once the trigger is removed the… |
