Today’s project is the porting of a mini dinosaur game by HonestQiao, who is a keen supporter of our Funpack activities. During the game porting process, a line-following sensor was added to check finger sliding actions, along with background music, so let’s take a look. The project has been uploaded to the Electronic Forest: https://www.eetree.cn/project/detail/1716 … Read more

What is the comparative performance of Arduino and STM32? Many electronics enthusiasts face a dilemma when choosing between Arduino and STM32. Arduino has always been popular, but STM32 offers more interfaces, stronger performance, and faster speeds? Features of Arduino and STM32 Arduino: Arduino is more geared towards creativity, simplifying hardware operations. Its functions and syntax … Read more
The fingerprint sensor is a widely used sensing element. This project takes the R502/R503 capacitive fingerprint sensor as an example to demonstrate how to enroll and detect fingerprints using the Arduino development board. The project BOM list is as follows: Arduino development board 1, fingerprint sensor R503 1, Dupont wires 20, breadboard 1. Understanding Capacitive … Read more
Click the above “Mushroom Cloud Creation” to follow us! 1. Overview A button switch, also known as a push button switch, was previously called a sensitive switch and is widely used in lights, socket switches, doorbells, and car central consoles. The introduction of button switches adds a layer of protection for electrical safety, making it … Read more
This experiment demonstrates how to control 6 servos simultaneously, which is the maximum number of servos that can be controlled by an Arduino Uno without using additional servo driver boards. It is important to note that the pins on the Arduino Uno that can connect to servos need to be PWM-enabled, which are the pins … Read more
