The line follower robot is an automated vehicle that follows a visual black line or path on the surface. This visual line is a path on which the line follower robot moves. It uses a black line on a white surface, or you can also adjust it as a white line on a black...

An Electric arc lighter is nothing but just a flameless lighter, which requires no fuel making it wind and travel-friendly. You can carry them in your pocket and can be useful in many applications. It just needs a 3 to 5-volt to power the electric arc lighter.   What is an Electric Arc Lighter?...

If you want to make your surroundings safer then it comes to security. What if you can protect your house or garage or any important belongings with the help of a laser system. Whenever the laser got interrupted, it will sound an alarm to make you alert that someone has invaded. So, In this...

Let’s take a look into a simple interfacing project this time. This is actuator interfacing with Arduino Uno and the actuator being servo motor, specifically SG90 servo motor. SG90 is a lightweight (just 9g) and tiny servo motor which has quite good output toque. We can use Arduino IDE to code this servo and...

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...

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...

In this tutorial, we are going to make a Touch Door Bell Alarm Circuit which will sound a melody with just a touch of a finger. This project uses a TTP223 capacitive touch sensor module which gives input to the musical IC that is amplified by  NPN transistor and hence melody is played on the speaker. Let’s make this Project.   BC547...
