In the previous article on getting started with Raspberry Pi (Part 3), I introduced how to drive a stepper motor. At that time, the stepper motor driven was a simpler one with lower precision. Today, we will drive a more complex stepper motor. Of course, I will still use Arduino as an example, but I … Read more
1. Introduction to Arduino Programming Arduino programming involves using the Arduino Integrated Development Environment (IDE) to write and upload code to Arduino microcontroller boards, typically implemented using an extension of C++ known as the Arduino language. The code is divided into two parts: setup() and loop(). The former runs once during board startup for initialization, … Read more
Continuing to fill the gaps, we have already written three articles about wireless communication with Arduino: Wireless Communication 1: 433MHz RF Wireless Radio Frequency Wireless Communication 2: nRF24L01 Module Wireless Communication 3: HC05/HC06 Classic Bluetooth BT Module Today we introduce another method of Bluetooth communication–BLE (Bluetooth Low Energy). What is BLE In “Wireless Communication 3: … Read more
Let’s explore Arduino together! Arduino It is an open-source electronic prototyping platform (an electronic design and development platform created based on open-source principles), which includes hardware (microcontroller-based circuit boards) and software (Arduino IDE, which stands for Integrated Development Environment). Its applications are extensive, ranging from smart home systems to robotics development, and from creative electronics … Read more
The Minor Snow solar term signifies the gradual onset of colder weather, and the season of falling snowflakes is approaching. During this time, designing a sensor capable of detecting snowflakes is particularly interesting and practical. This article will boldly envision three theoretical design schemes to help everyone better understand and apply this technology. The first … Read more
