What is Serial and SoftwareSerial of Arduino: Explained
In electronics, serial refers to a method of transmitting data where each bit is sent sequentially, one after the other, over a single wire or communication channel. This is in contrast to parallel transmission, where multiple bits are sent simultaneously over multiple wires. In a serial communication system, data is typically transmitted using a specific protocol that dictates the format and … [Read more...]

Why Do We Need Oscilloscopes?
An oscilloscope is an electronic measuring device that, in its preferred application, makes the temporal course of one or more electrical voltages visible on a screen. The oscilloscope represents a progression graph in a two-dimensional coordinate system, where the (horizontal) x-axis is usually the time axis and the (vertical) y-axis is the stress axis. The resulting image is called an … [Read more...]

How Load Cell Sensor Works (Weighing Scale Sensor)
Load cells are a special form of force transducers (force sensors) for the construction of weighing devices, i.e. for weighing with scales. They are calibrated in grams (g) kilograms (kg) or tons (t), not in newtons (N) like the force transducers. In practice, however, far more load cells are used as force transducers. Load cells are essential components in various industrial, commercial, and … [Read more...]
