Here we will show how to read circuit diagrams for beginners in electronics. Learn to read electrical and electronic circuit diagrams or schematics. A drawing of an electrical or electronic circuit is known as a circuit diagram, but can also be called a schematic diagram, or just schematic.

In this tutorial we take a look at exactly what getting into building electronics projects involves, the kinds of great gadgets you can build yourself, what you'll get from spending your time with electronics, and what you need to commit to take the plunge.

In this Arduino Tutorial we will learn how the HC-SR04 Ultrasonic Sensor works and how to use it with the Arduino Board to do interesting hobby projects like object avoidance robot, range finder and it is by far one of my favourite sensors...........

The Arduino is an open source prototyping platform based on the Atmel Atmega series micro controllers used for different applications like making a led turn off and on, home automation, robotics and many more. Arduino is based on easy to use, flexible, hardware and software. It's made for artists, designers, engineers, hobbyists and anyone with the slightest interest in programmable electronics.

In many modern-day circuits, the switching action is performed by a relay, which in turn activates an external load but the power consumed by the relay may be unsuitable for battery-powered applications.
