Lockout and tagout in electrical safety
Electrical “lockout” is the process of removing the source of electrical power and installing a lock, which prevents the power from being turned ON. Electrical “tagout” is the process of…
Grounding and bonding for electrical systems
Proper grounding practices protect people from the haz-ards of electric shock and ensure the correct operation of overcurrent protection devices. Intentional grounding is required for the safe operation of electrical…
Recognize Symbols – Abbreviations – Ladders used on motor and control diagrams
Different types of electrical drawings are used in working with motors and their control circuits. In order to facilitate making and reading
A beginer’s guide to Arduino Variables – If – Loop – Function
Variables Variables give a name to a number. Actually, they can be a lot more powerful than this, but for now, we’ll use them for this purpose. When defining a…
Arduino Data Types(Basic knowledge for beginer)
A variable of type int in Arduino C uses 2 bytes of data. Unless a sketch becomes very memory hungry, then ints tend to be used for almost everything, even…
Using Libraries Arduino (Basic knowledge for newbies)
Because Arduino boards have a quite limited amount of memory, you’ll find it worthwhile to only include code that will actually be used in what ends up on the board.…
From Sketch to Arduino
Now that you have an understanding of where all the magic code comes from when you write a simple Arduino sketch, let’s look at exactly how that code gets into…
Overview of Arduino and Wiring
The Wiring framework gives Arduino its easy-to-use functions for controlling the hardware pins; however, the main structural part of the language is all provided by C. In early versions of…
AVR Processors – The Arduino Family
The Arduino family of boards mostly use microcontrollers made by the company Microchip. They all have similar hardware design principles and, with the exception of the microcontrollers used in the…
How to modify the Arduino’s Blink Sketch
It may be that your Arduino was already blinking when you first plugged it in. That is because the Arduino is often shipped with the Blink sketch installed. If this…
