An Arduino/Genuino UNO R3 or Arduino Nano 3.x board. Other Arduino boards (MEGA2560, Micro, Mini, etc) work as well, but some of the instructions may be slightly different. An RGB LED. For this tutorial we'll use a common cathode one (common GND pin for all three LEDs). Three re...
Arduino Blink LED Code All Arduino code is structured around the two main functionssetup()andloop(). Thesetup()function runs only once when the Arduino board starts up. It is used for initializing variables, pins, and other settings. Theloop()function runs repeatedly after the setup() functio...

1 .Arduino mega 2560 主板 我们将Arduino mega 2560作为主板,用它向从板Uno发送经过Modbus协议打包后的消息帧,我们在此使用RTU消息帧模式,将要发送的消息帧定义成五位数组的模式,包括8bit主板地址码,8bit功能码,8bit数据位及16bit的CRC校验码,利用CRC校验保证传输消息的正确性,消息帧中的功能码则对应与从板的不...
The Diyode Codeshield is an arduino shield (add-on board) designed to make the process of learning (and, more importantly, teaching) arduino much more engaging and accessible. By removing all the obstacles that typically interfere with the learning process, we can greatly improve understanding, ...
To do this, we’ll use a custom sketch that will show us exactly what the Arduino sees when we bring our magnet near. #define ENCODER_A 14 #define ENCODER_B 15 #define ENCODER_PORT PINC #define SWITCH 13 #define BUTTON 12 #define RGB_RED 11 ...
