Smartwatch vs Mechanical Watch
In today's digital age, the wristwatch has evolved beyond its traditional role as a timekeeping device to become a stylish accessory. With the emergence of smartwatches and the enduring appeal of mechanical watches, consumers now face a choice between two distinct types of timepieces. In this article, we'll explore the differences between smartwatches and mechanical watches, helping you navigate … [Read more...]
Basics of Legged Robots
Legged robots are special robots that can move with the help of "legs". This is already possible with only one "leg" (hopping). As a rule, however, four-legged, six-legged or even bipedal machines are used. There are machines that have even more legs, but these can be traced back to the six-legged version. An early object of investigation was the different types of horse gait. The photographer … [Read more...]
What is an Actuator?
Actuators are usually drive components that convert an electrical signal (commands issued by the control computer) into mechanical movements or changes in physical quantities such as pressure or temperature and thus actively intervene in the controlled process. It is a branch of drive technology that deals with the actuator as a technical element. The term actuator generally encompasses the … [Read more...]
Brushless DC Motor: Basic Details
The brushless DC motor is often powered by direct current from batteries but is not a simple direct current machine with carbon grinders, but uses control electronics to convert the direct current into suitable three-phase current for operation as a three-phase synchronous machine with excitation by permanent magnets. The three-phase winding is controlled by a suitable circuit in such a way that … [Read more...]

How to Blink an LED Only Twice After a Button Press Using Arduino
Blinking an LED is one of the most basic projects for Arduino beginners. Previously, we have demonstrated how to Blink LED and Beep Every X Seconds Upon Push Button Press. However, adding a condition to blink the LED only a certain number of times after a button press introduces a new level of complexity. In this tutorial, we'll explore how to achieve this functionality using an Arduino board, an … [Read more...]
How to Write Code for Arduino with ChatGPT (GPT 3.5/4)
In our earlier articles, we have explained about the trending topics such as What is Generative Programming, How GPT-engineer Works to Generate Code and How to Develop a Simple WordPress Plugin with ChatGPT (GPT 3.5/4). In the realm of the Internet of Things (IoT), Arduino and ESP32 are widely used microcontroller platforms known for their versatility and ease of use. However, coding for these … [Read more...]
What is Field-Oriented Control (FOC)
Vector control, also known as field-oriented control (FOC), is a control concept in which sinusoidal – or assumed to be largely sinusoidal – alternating variables (e.g. alternating voltages and alternating currents) are not regulated directly in their temporal instantaneous value, but in an instantaneous value adjusted for the phase angle within the period. For this purpose, the recorded … [Read more...]
