“How does an actuator work?” is one of the most common questions in motion design — and a fair one. Linear motion hides a surprising amount of mechanical nuance behind a simple-looking part. This guide breaks down the definition, internal components, and operating principles of an electric linear actuator so you know exactly what is happening inside the housing when one extends and retracts. KEY TAKEAWAYS An actuator converts energy into controlled motion — for electric linea

Better Angles. Better Flow. Better PCBs. Figure 1: Visual comparison of 90°, 45°, and Arc/Fillet trace routing on a PCB Introduction PCB trace routing is far more than connecting dots on a board. Every bend, corner, and curve in a copper trace directly affects signal integrity, manufacturing yield, and long-term reliability. Among the most misunderstood aspects of PCB layout is the treatment of trace angles — specifically, why the industry standard strongly discourages routi

STM32CubeIDE is a powerful Eclipse-based development environment used for building and debugging applications on STM32 ARM microcontrollers. It provides integrated tools for code generation, compilation, and debugging. For advanced debugging scenarios, external debug probes such as PEMicro Cyclone and PEMicro Multilink can be used. These devices extend debugging capabilities through a dedicated Eclipse GDB plugin, enabling seamless integration with STM32CubeIDE. This article

In this article, I will show how I analyse I2C communication using a Saleae logic analyzer. This tutorial explains the basic setup, how to capture signals, how to enable the I2C protocol analyzer, and how to understand the decoded data. The same method can be used when debugging communication between a microcontroller and peripheral devices such as sensors, EEPROM, or display controllers. I2C is one of the most used serial communication protocols in embedded systems. It use

Understanding STM32H503 and Its Security Features The STM32H503 family from STMicroelectronics is built on the ARM Cortex-M33 core. It includes an advanced security lifecycle as part of the STM32H5 architecture. Unlike older STM32 series, STM32H5 devices support controlled product states. This allows a device to be provisioned, secured, locked, and later reopened through an authenticated regression process. This mechanism is essential for secure production environments where

The Local Interconnect Network (LIN) uses a master-slave architecture consisting of one LIN master and one or more LIN slave nodes. Communication begins with a message header, which includes a break field to indicate the start of the frame and a sync field that allows slave nodes to synchronize their clocks. The identifier (ID) field contains a 6-bit message ID along with a 2-bit parity field. This identifier defines the type of message rather than the destination node. Once
