System On Chip (SoC)
A system-on-chip (SoC) is the integration of functions necessary to implement an electronic system onto a single substrate and contains at least one processor. The only real difference between an SoC and a microcontroller is one of scale.
An SoC contains multiple processing parts, memory, modems, and other essential bits and pieces manufactured together in a single chip that’s soldered onto the circuit board.
Photonics is the science of light. It is the technology of generating, controlling, and detecting light waves and photons, which are particles of light. The characteristics of the waves and photons can be used to explore the universe, cure diseases, and even to solve crimes. Scientists have been studying light for hundreds of years. The colors of the rainbow are only a small part of the entire light wave range, called the electromagnetic spectrum. Photonics explores a wider variety of wavelengths, from gamma rays to radio, including X-rays, UV and infrared light. Continue reading

voltage is the measure of work required to move a unit charge from one location to another, against the force which tries to keep electric charges balanced. In the context of electrical power sources, voltage is the amount of potential energy available (work to be done) per unit charge, to move charges through a conductor. Continue reading

What is the Arduino used for?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online.
How does a Arduino work?
The Arduino board is connected to a computer via USB, where it connects with the Arduino development environment (IDE). The user writes the Arduino code in the IDE, then uploads it to the microcontroller which executes the code, interacting with inputs and outputs such as sensors, motors, and lights. Continue reading

What is a Diode?
Let’s start by answering the most basic question. What is a Diode?
The two terminals are named as Anode and Cathode, we will get into the symbol and how to identify the terminals later, but for now just remember that any diode will have only two terminals (at least most of them) and they are Anode and Cathode. Another golden rule with diodes is that they allow current to pass through them in only one direction that is from Anode to Cathode. This property of diode is what makes it useful in many applications. Continue reading
