Introduction to Digital Tubes The pins related to data of 74HC595 can be divided into three categories: DS: Serial data input, connected to a certain digital I/O pin of the microcontroller. Q0~Q7: 8-bit parallel data output, can directly control 8 LEDs or the 8 pins of a seven-segment digital tube. Q7′: Cascade output terminal, connected … Read more

Recently, a research team from Yale University did something interesting: they designed the well-known rigid Arduino boards into flexible, stretchable circuits and integrated them into soft robots, achieving 300% high stretchability and providing advanced computing capabilities for soft robots. This groundbreaking work was successfully published in Science Robotics (IF=26.1). To achieve functionality in the real … Read more
As a beginner with Arduino development boards, it can be very challenging for those without an electronics background, and you will encounter many mistakes, some of which may have simple solutions but may take days to resolve. Therefore, to make things easier, I have created a list of the 10 most common Arduino mistakes along … Read more
01 Introduction In the previous two articles: “Open Source! A Step-by-Step Guide to Building an Arduino + NVIDIA Jetson ROS Car (Part 1)” we introduced the hardware needed for a Jetson Nano car; in “Open Source! A Step-by-Step Guide to Driving Arduino + ROS Car Motors” we discussed how to use Arduino and its expansion … Read more
Today, I will share how a senior communications engineer, 【Urban Wood】, implemented an SDR FM player using the graphical programming tool GNU Radio on Windows, and added stereo modulation functionality. Here we go, enjoy! Funpack Activity Report – Issue 5 Part One: Completion Status of Activity Tasks I chose the first topic, the FM player. … Read more
Getting Started with Arduino: Engaging Children in Electronics and Programming Dear parents, do you want your children to learn useful knowledge and skills while having fun? Do you want them to cultivate their creativity and imagination while exploring the world? Do you want them to understand how technology works while enjoying its conveniences? If your … Read more
This tutorial will specifically introduce how to modify the Arduino part of the ROSArduinoBridge code. This code is the main code for the lower computer mobile chassis, running on the Arduino Mega2560 main control board, which is used to control the chassis motor rotation and receive feedback from each motor encoder, thus allowing the mobile … Read more
This tutorial introduces how to debug the Arduino code on a real omnidirectional mobile chassis. Only by debugging the code of the lower computer can we ensure that the upper computer code runs normally. Here, the upper and lower computers communicate through the USB to TTL serial port of the lower computer. First, let’s introduce … Read more
