Introduction Similar to Arduino IDE, Platform-IO is a programming environment for all types of microcontrollers. It provides an easier programming process and is available as an extension for the VS Code software. One notable advantage of Platform-IO IDE over Arduino IDE is that it automatically selects the appropriate port. In addition, Platform-IO IDE offers code suggestions to help complete and modify your code, and it eliminates errors caused by case sensitivity in Arduino IDE! Some other attractive fea...

Introduction RFID, which stands for radio frequency identification, enables data reading and identification of unique tags using radio waves. RFID modules operate on specific frequencies, requiring tags that match the reader module's frequency. In this article, we will design and implement a simple identification system using a 125KHz RFID module and the Wiegand protocol. Tip While the RFID module used in this article shares similarities in shape and structure with the RDM6300 RFID reader m...

Introduction The BIOS, or Basic Input/Output System, is a firmware that controls the boot process and the hardware settings of your computer. Sometimes, you may need to update or repair the BIOS to fix some issues or improve the performance of your computer. However, flashing the BIOS can be risky, as it may cause your computer to become unbootable or unstable if something goes wrong. One of the tools that you can use to flash the BIOS safely and easily is the CH341A programmer, which is a cheap and ve...

Introduction If you are interested in sensors, you are probably familiar with proximity detection sensors. There are various sensors available for proximity detection; each with its own capabilities and limitations. One method is to use the infrared transceivers. These sensors measure the time it takes for an infrared beam to travel back and forth and calculate the distance between the sensor and the target surface.In this tutorial, we’ll introduce the TMD27713 distance detection sensor. Whether you...
