A Programmable Logic Controller (PLC) is a specialized computing device used extensively in industrial automation to provide control over equipment and processes. Unlike traditional hardwired control systems, PLCs are fully programmable, offering far more flexibility, ease of troubleshooting, and adaptability to changing operational needs. Moreover, they are designed to withstand challenging industrial environments ranging from exposure to high temperatures to dusty or wet conditions, making them very dependable. In this blog, we will explore all there is to know about PLCs, including their primary components and the skills required for programming them.

In the world of electronics, having precise control over electrical currents is essential for various applications. Whether it is adjusting the brightness of a light, regulating the speed of a motor, or fine-tuning the volume of an audio device, the ability to modulate electrical resistance is paramount. This is where components known as rheostats come into play, offering a versatile solution for managing current flow within a circuit.
