This tutorial introduces the ros_arduino_bridge open source package. If you are creating a ROS mobile robot based on Arduino, this package provides a complete software solution. The package not only controls the motors to drive the chassis but also includes data acquisition from ultrasonic sensors and infrared distance sensors, as well as various general analog … Read more
Funpack is a year-long “Play to Win” event initiated by Hard禾 Academy in collaboration with Digi-Key. Each month, we will introduce a top-tier semiconductor manufacturer’s development board/instrument kit. If you can play with it according to the specified goals within a month, you can receive substantial rewards. Finally, the troublesome year of 2020 is over. … Read more
First, let’s review some background information (of course, you can skip this part). Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team during the winter of 2005, including members such as Massimo Banzi, David … Read more
This weekend, Sosi will take you to experience the real Arduino! The course is open to all members of Sosi and moderately open to the public. The main purpose is to let many students who have not been exposed to hardware quickly get in touch with it, generate interest in hardware, and understand the basic … Read more
We have traditionally viewed Intel and Arm as the dominant players in the PC and server markets, and the mobile application domain, respectively. Although these companies have attempted to cross into each other’s territories in the past, they have not been particularly successful. However, at the 2018 Computex conference, “diversification” became the main theme. Traditionally, … Read more

In the past, low power consumption and high computing power processors were clearly distinct. For example, Arm, which originated from Acorn, was fundamentally based on low power consumption — in the early years of the ARM instruction set development, it was hardly considered to compete with high-performance instruction sets like x86 or POWER. To the … Read more
