Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform that includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005. It is built on an open-source simple I/O interface and has a development environment similar to Java and C language … Read more
【Click on the above「Blue Text」 to follow DF Maker Community and become a tech aesthetics enthusiast】 Happy Dragon Boat Festival to everyone! This week we will look at how to make a “hollow clock” with only hands and no dial using Arduino. It looks pretty cool. Let’s enjoy a few pictures shared by netizens who … Read more
Today, Teacher Cheng from the Marker Pen Design Study Abroad program continues to explain the relevant knowledge of Arduino. Previously, we introduced many Arduino sensors in the article “How to Use Arduino Human Infrared Sensors”. In this article, we will discuss the programming language within Arduino, specifically the application of some common functions. Arduino is … Read more
MAKER: Shiura ／Translated by: Qu Wujin The fifth generation of the “Hollow Clock” is a comprehensive improvement and refinement based on previous versions. This clock features a thinner and cleaner ring design (only 7mm), complete with scale markings. Its appearance has almost no exposed screw heads (except for the center of the hands), making the … Read more
Before the invention of the breadboard (in the 1960s), you had to use a technique called wire wrapping to build circuits. The wire wrap connects the circuit by linking conductive posts to a perforated board and winding wires around them. As shown in the image below, the circuit can be quite complex. The circuit board … Read more
Today, I will share with you the DC-DC boost circuit. This mainly concerns: DC-DC boost circuits, DC-DC boost module principles, and how to construct a DC-DC boost circuit. 1. What is a DC-DC Converter? A DC-DC converter is a type of power electronics circuit that can effectively convert direct current from one voltage to another. … Read more
Source: Semika Original Author: Semika Integrated circuits are a collection of electronic components: resistors, transistors, capacitors, etc., all packed into a small chip and connected together to achieve a complex functional goal. They have many functional categories: circuit logic gates, operational amplifiers, timers, voltage regulators, circuit controllers, logic controllers, microprocessors, memory and so on. Integrated … Read more
A few days ago, a frustrating problem left me quite unhappy.The final solution was simple, but the problem itself had me deep in thought. I thought it was time to tidy up the messy breadboard circuit, as all the issues began at that point. (Note: These circuits are mainly used to drive my Cunning Chronograph). … Read more
