Q: How can I see articles like this every day? A: Just search for the public account “51 Microcontroller Learning Network” and follow it for free Readers who work with microcontrollers should have heard of Arduino or even used it, but many friends are still unclear about what Arduino actually is. Today, I will briefly … Read more
Dear friends! Previously, we introduced “War Equipment: DIY Ultrasonic Radar with Intel Edison,” and this time we will bring you a similar function using the Arduino you have at hand, achieving the same functionality at a lower cost. It’s simple to learn and offers great value. Here’s the video for you. Click here for the … Read more
This robot car is very simple. It uses ultrasonic sensors to measure the distance in front and the Arduino controls the car to move forward, backward, or turn left and right based on the received distance. In other words, it has its own way of “thinking” and can wander around a room without bumping into … Read more

Introduction This article covers the following topics: What is the difference between Single-Ended Input and Differential Input? What are Fully Differential, True Differential, and Floating Differential? What are Reference Voltage (Vref) and Common Mode Voltage (Vcm)? Single-Ended Input The simplest connection between a sensor and an ADC is the Single-Ended Input. In this connection, the … Read more
MAKER：diyperspective/ Translated by: Fun Endless Scrolling text displays are widely used in various occasions such as billboards, train stations, bank counters, toys, and even wearable electronic badges… Have you considered DIYing this feature? It is quite simple for Arduino, as you can use the existing Arduino libraries to display letters from A-Z, which is quite … Read more
Software Introduction Arduino is an open-source electronic prototyping platform. In terms of hardware, there are various development boards, such as Uno, Mega, etc. The development boards have rich interfaces, including power interface, digital and analog pins, which can connect sensors and actuators. On the software side, it mainly uses C/C++ programming, and the Arduino IDE … Read more
Summary: Recently, it has been snowing in many places, including Hunan, Hubei, and Xi’an. Students who raise tropical plants and pets need to pay more attention to the indoor temperature. Below is a practical and easy-to-make thermometer. It is built using the DS18B20 temperature sensor and OLED module, with the development board being Arduino. The … Read more
Using Sensors to Determine the Molar Volume of Gases Ma Xiongxiong Southwest Weiyu Middle School, Shanghai Abstract: Based on the Arduino platform, a gas volume measurement device has been improved by incorporating a BME 280 (temperature, pressure, humidity) sensor and a mini submersible pump. The enhanced device can not only acquire data on temperature, pressure, … Read more
