The TM1637 four-digit seven-segment display module is a 4-digit common anode display module (0.36 inches) with a clock point. The driving chip is TM1637, and the driving method is IIC, so only 2 signal lines are needed to control the 4-digit 8-segment display (the brightness of the display can be adjusted in 8 levels). Module … Read more

Drones are unmanned aerial vehicles, ranging from micro-drones to multi-rotor quadcopters. Sometimes drones are even equipped with cameras, allowing users to view and record aerial footage. Drones consist of many components; one of the most important is the flight controller, which is essentially the brain of the drone. Arduino development boards are particularly well-suited for … Read more
The Internet of Things (IoT) includes billions of physical devices connected to the internet around the globe, which upload data and communicate with each other independently of human input. Arduino produces a range of development boards, from 8-bit microcontrollers to 32-bit microcontrollers, some even with WiFi and Bluetooth capabilities. Coupled with beginner-friendly projects available online, … Read more
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

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
