When it comes to performance, there's a world of difference between the Raspberry Pi and Arduino. The former, after all, is technically a fully functional computer that can run games, word processors, ...

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 ...

This is a two-part series where DI authors Damian and Phoenix Bonicatto explore the IQ signal representation and negative frequencies. Part 1 explains the commonly used SDR IQ signal representation ...

在本篇文章中，我们将使用STM32和RFID读卡器设计一个读取RFID卡的系统。 RFID表示射频识别，它使用无线电频率读取信息。 RFID用于许多认证系统，如电梯乘坐系统、自动收费系统、医院患者信息维护系统、自动数据收集等。本文中，我们将学习如何使用STM32F103C8微 ...

We come across Liquid Crystal Display (LCD) displays everywhere around us. Computers, calculators, television sets, mobile phones, and digital watches use some kind of display to display the time. An ...

In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are ...

This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...

Capacitive sensors are widely used to measure various physical and chemical process parameters such as displacement, acceleration, thickness, force, pressure, stress, level and humidity. The measured ...
