Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...

The most difference to the original LiquidCrystal library from Arduino is that this library supports printf() functionality. When using PlatformIO and AVR, to support float you must add following line ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

[导读]您有一个微控制器和两个相同的传感器，这意味着它们具有相同的I2C地址。如果没有多路复用器或配置传感器的I2C地址的可能性，则无法将它们连接到相同的I2C总线。然而，Arduino Uno R4 Wifi在板上提供多个I2C总线。一个I2C总线在引脚上可用，另一个在Qwiic ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

Yes, you can program Arduino with Python using the PyFirmata library. While Arduino traditionally uses C++ code, Python can control Arduino boards through the Firmata protocol, allowing you to ...

If an Arduino port is not showing up, your USB connection might be faulty or the ports may be disabled entirely. We will show you how to enable a port in Arduino and look it up in the Device Manager.

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Whether you're making the first steps in a new and exciting learning journey or you're on the verge of making a discovery that will revolutionize circuit design, having a test environment is paramount ...
