在Arduino IDE中打开messaging.ino并将其上传到您的Arduino UNO中。 关闭Arduino电源,然后将Bluetooth Bee放置在无线扩展板上。请确保Bluetooth Bee不在AT模式下,并且将无线扩展板串行选择开关切换到MICRO位置。 用9V电池为Arduino Uno供电,并使用“1234”作为密码与您的Bluetooth Bee配对。确认配对成功后,您可以在设备管...
The Arduino Nano Every contains the ATMega4809, a more powerful processor than the one in the Arduino UNO board. This allows you to compile a more advanced program, as it has 50% more program memory than the Arduino UNO ATmega328P. It also has 200% bigger RAM than UNO. If you are us...
Arduino Uno是处理所有数据的发射器侧的主控,RF发射器模块用于将所选数据发送到接收器。射频发射器模块的数据引脚连接到Arduino的数字引脚12,而VCC和GND引脚分布连接到Arduino的5V和GND引脚。 接收器部分的电路连接 该项目的接收器部分包括一个Arduino Uno、RF接收器、1602 LCD模块和I2C模块。RF接收器用于从发射器部分...

This is a preprogrammed Atmega328P chip, useful if you want to make your own Arduino-compatible or repair a damaged chip on an exisiting Arduino UNO, Duemilanove, Diecimila, or NG! This chip is programmed with 'ADAboot', my version of the bootloader that is "quick-start" NG/diecimila/due...
如果使用Arduino UNO或者NANO开发板,请将原理图中的11脚和12脚调换位置,因为UNO和NANO的11和12正好与PRO MINI相反! 原理图 元件连接图如下: 元件连接电路图 3. 软件部分 SBUS协议使用波特率为100000、8个数据位,偶数奇偶校验位和2个停止位的反向串行逻辑。SBUS数据包的长度为25个字节,包括:字节[0]:SBUS头,0x0...
