Protection circuits, like reverse polarity protection, short-circuit protection, and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mishap. Generally fuse or MCB is used for overvoltage protection. Here in this circuit, we will build a simple overvoltage protection circuit without using a fuse.

There are many types of Robots, from the simple ones like a Toy car to the advanced ones like industrial Robots. We have already covered many types of Robots using different technologies, have a look at them:

GPS is the short-form of Global Positioning System. It is a system which provide accurate Altitude, Latitude, Longitude, UTC time and many more information, which are taken from 2, 3, 4 or more satellite. To read data from GPS, we need some Microcontroller and we already interfaced GPS with Arduino and with Raspberry Pi.

We have selected G7020 GPS…

The process of converting alternating current into direct current is rectification. Any offline power supply unit has the circuit for rectification which converts either the AC wall supply into a high voltage DC or stepped down AC wall supply into low voltage DC. The further process will be filtering, DC-DC conversion and etc. So, in this article we are going to discuss…

In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name LED matrix.

These matrixes can be made by…

In previous article we have seen about ADC conversion using STM32. In this tutorial, we will learn about PWM (Pulse Width Modulation) in STM32 and how can we control brightness of LED or speed of DC fan using PWM technique.

We know that there are two types of signal: Analog and Digital. Analog signals have voltages like (3V, 1V...etc) and digital…

Arduino is an excellent way to simplify and speed up your microcontroller projects, thanks to its community of developers who have made almost everything look simple. There are lots of Arduino Projects out here for you to try and have fun. Some of your projects might need some sounds action to notify about something or just to impress the viewers. What if I told you…

Creating a Local Network to share personnel and confidential data's has become almost impossible for a common man in our modern world. This is mainly because all common chat methods like Whatsapp, Facebook, Hangout and almost everything involves an internet connection.

What if, we could share data without the medium of Internet?

As we all know Raspberry Pi is a wonderful Developing platform based on ARM microprocessor. With its high computational power it can work out wonders in hands of electronics hobbyists or students. All this can be possible only if we know how to make it interact with the real world. There are many sensors which can detect certain parameters from the real time world and…

You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after some time. A number of technologies are available to make such kinds of systems, like PIR sensors, Radar sensors,  Laser sensors, Infrared sensors, etc. In this Arduino based automatic door…

This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. There are two important components in this circuit, first is PIR Sensor (Passive Infrared Sensor) and second is Relay.

PIR Sensor

PIR…

We have previously created a complete and detailed tutorial on Phase Shift Oscillator. Here we will see practical implementation of phase shift oscillator. In this project, we create phase shift oscillator circuit on breadboard and test its output using oscilloscope.

Phase is a full…
