Arduino function APIProgram StructureIn Arduino, the standard program entry main function is internally defined, and the user only needs to be concerned with the following two functions:void Setup ()void Loop ()The setup () function is used for initialization, and the loop () function is used for execution. Initialization functions are generally placed at the beginning of the program, to set some pin output
Recently, I intend to customize an Arduino board, change the Arduino's burn-write mechanism. Fortunately, bootloader are active code, say dry, before rewriting of course to try this source can compile, but to the bootloader directory is dazed .... Actually use is makefile, but as a program ape of course can't retreat ...1. Find bootloader Source codeBootloader source code are in the \arduino-1.6.9\hardware\

adding sound or music to our project will always make it look cooler and sound more appealing. Especially if you're using the Arduino Development Board, and you have a lot of spare pins, you just need to add an SD card module and a normal speaker to easily add sound. In this article, I'll show you how easy it is to use your Arduino Development Board to play music and add sound. Thanks to the

Arduino is an open source hardware platform that includes development kits (development boards and related modules as well as wiring) and Ides, and the development language is based on C. The core is a 8-bit ATmega328 processor, this processor is the AVR MCU series of high-end products. The Arduino provides a digital interface and an analog
prompt for system files not found when updating drivers manuallycause of the problem:we can open C:\Windows\inf\setupapi.dev to open the hardware installation log. Finding the last record, we will find the following error:sto:copying driver package files to ' c:\users\admini~1\appdata\local\temp\{7ff41925-97db-1c6a-d5b E-311dd1322b22} '.inf:opened inf: ' D:\arduino-1.0.2\drivers\arduino uno.inf ' ([strings]
The USB interface used by the Arduino to communicate with the computer is the USB interface used to download the program, and when Arduino communicates with other devices, it needs to use the "Serial" series of functions, so we have to know about it, here are a few common " Serial"function.1, Serial.begin ()-Sets the rate at which the serial data is transmitted per second (baud rate). When communicating wit
Through the first two articles, we have become familiar with the basic GPIO programming of Arduino and the serial communication between PC and Arduino. Next we're going to start learning all kinds of sensor operations while delving into Arduino programming.
Before we start programming, we need to be familiar with the principles of SR04. Here is a digression: the
This article focuses on how the Arduino Development Board works from a hardware perspective.
Most of the articles are about Arduino software. However, an in-depth understanding of its hardware design can help you take a solid step in the Arduino journey. Mastering the electronic design of the Arduino hardware will hel
Always heard that many do IoT, smart Home controller using the Arduino, studied brother there got an Arduino development board, a afternoon study, feel this suitable for children play:)Talk less, sum up, it is easy to use later. I mainly refer to the Baidu Library of a 60+ page of "Arduino from scratch" and some technical forums such as Geek Workshop bar. As a re

Arduino consists of two main parts: the hardware part is a Arduino circuit board that can be used for circuit connection, and the other is the Arduino IDE, the program development environment in your computer. You just write the program code in the IDE, upload the program to the Arduino circuit board, the program will
