An LM555 timer paired with an NTC thermistor makes a simple, configurable ON/OFF thermostat for heating or cooling.

A two digit counter is an electronic device that counts from 00 to 99 and displays the count on two 7-segment displays. With each clock pulse, the displayed value increments, resetting to 00 after ...

Abstract: In a recent series of electric field sensing experiments, a theremin was used to measure the mutual capacitance between a human being and a length of electrical wiring. The instrument, based ...

When the piezoelectric device (PZT) detects a mechanical impact, it emits a signal that triggers the monostable (IC1), which in turn controls the output of the dual LED/phototransistor opto-coupler ...

Various digital circuits require push-pull power drivers, particularly for gate and line driver applications. Many special-purpose devices are available for these issues, but they are typically ...

Add a description, image, and links to the astable-multivibrator topic page so that developers can more easily learn about it.

Frequency to voltage converter converts the frequencies or pulses to the proportional electrical output such as voltage or current. It is an important tool for electromechanical measurements where ...

Timer chip LM555 (IC1) is wired as an astable multivibrator. Components R1 and R2, VR1 and C1 produce the free-running frequency. You can adjust it to some extent by varying potentiometer VR1. The ...

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 ...
