Changlu Electric Cup
Midterm Review Results Announced
After careful evaluation by the judges, the midterm review results for both the lower and upper grade groups of the Changlu Electric Cup have been announced. The top six teams in the upper grade group and the top eight teams in the lower grade group will advance to the finals to compete for the final prizes!
Now, without further ado,
Getting to Know Arduino:
Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It consists of two parts: the hardware part is the Arduino circuit board used for circuit connections; the other part is the Arduino IDE, which is an application that provides a programming development environment, integrating code writing, analysis, compilation, and other functionalities into a single software.
Arduino can sense the environment through various sensors and can also control lights,
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 to the DS of the next 74HC595 to achieve cascading between multiple chips.
There are four pins related to control of 74HC595:

The main control chip is NXP's IMXRT1011, with an ARM Cortex-M7 core. The IMXRT1011 is a microcontroller unit (MCU) developed by NXP Semiconductors. It belongs to the i.MX RT series of MCUs, based on the Arm Cortex-M7 core, with a maximum frequency of 500 MHz.
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 with possible solutions.

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 board to achieve differential control and PID speed regulation of two DC geared motors.
Today, we will explain how to configure ros_arduino_bridge in Jetson Nano, how to configure
