Opening Autonomous Driving Intelligent Era German Karl Benz invented the world’s first horse-drawn three-wheeled vehicle in 1885 and obtained the world’s first automobile invention patent on January 29, 1886, which has been 134 years ago. This day is known by most people as the birthday of the modern automobile, and Benz is honored as the … Read more
Example Effect Press the serial monitor, and you can see that the measured distance is 9.8cm-10.1cm with an error of about 0.2cm. HC-SR04 An ultrasonic sensor used for distance measurement, widely applied in robotics to avoid obstacles and measure distances. Its module uses Trig to trigger distance measurement, which emits 8 40kHz square waves and … Read more
What is Arduino? What is it? Many parents and children have heard the name “Arduino”, but they may still be confused about what it actually is. This mysterious little device sounds quite sophisticated. Is it meant for engineers? Or is it a strange game console? Actually, it is a magical tool that can ignite children’s … Read more
In this article, we will learn about the working principle of servo motors and how to control them using the Arduino development board and the PWM driver PCA9685. There are many types of servo motors, and their main feature is the ability to precisely control the position of the shaft. A servo motor is a … Read more
DIY Simple Mechanical Arm with Arduino Introduction The mechanical arm consists of Arduino, servos, and MeArm hardware. The Arduino controls the servos through programming, enabling the functionality of the mechanical arm. There are two types of servos: analog servos and digital servos. Digital servos (Digital Servo) and analog servos (Analog Servo) are fundamentally the same … Read more
01 Introduction In the previous articles, we mainly recorded how to drive TT motors with Hall encoders and low-power DC gear motors using our Arduino Mega 2560 expansion board (with TB6612). “Open Source! A Step-by-Step Guide to Driving Motors with Arduino+ROS Car” “Open Source! A Step-by-Step Guide on How to Adjust Encoder Motor Speed PID” … Read more
