Simple Clap Switch Circuit using CD4017 IC

Harsh Sehgal 0 Comments

In this tutorial, we are going to make Clap Operated Switch using CD4017 Decade counter IC. It consists of a condenser microphone that senses the clap sound and gives a clock pulse to the Decade counter IC which in response turns the ON or OFF the relay. With the first clap IC gives the HIGH...

Automatic Power cut-off Circuit using 555 Timer IC

Harsh Sehgal 0 Comments

In this tutorial, we are going to make an Automatic power cut-off circuit with the help of a 555 timer IC and other components. This circuit automatically cut-off the power after some prescribed time which can be varied with the help of a potentiometer. There are large applications of the circuit, for example, if we want to...

Raspberry Pi took the maker market by wonder when they released their first single board computer in 2012. It wasn't like anything anyone had seen before. It was a credit card sized, fully capable Linux computer that retailed for only INR 2.5k (35 dollars). It was groundbreaking! Since then, they have released many other...

Interfacing GT511C3 Fingerprint Sensor with Arduino – Enrol and Detect Fingerprints

Quartz Components 0 Comments

In this article, we will discuss the GT511C3 finger-print sensor and how to interface it with Arduino. We will learn how to use the sensor with Arduino to enroll finger-prints on it and then detect the fingerprints whenever required. We will also show a red and green LED signal for verified and unknown finger respectively...
