我的arduino Uno连接到蓝牙模块(hm-10),它们通过arduino tx,rx引脚通过uart连接。有些奇怪的事情发生了: arduino正在启动与模块的串行通信时,他们得到了电力。 然后其他一些设备连接到模块(他们配对的无线) 这里,Arduino与模块的连接以某种方式丢失,为了将数据从模块的UART获取到Arduino,我必须在这里重新设置-- arduino...
是指在Arduino编程中,如果将变量定义在setup函数之外,即在全局范围内,该变量可以在整个程序中使用,包括循环函数loop()以及其他自定义函数中。 优势: 1. 全局变量可以在不同的函数中共...
void loop () { } // in function modifyArray, "b" points to the original array "a" in memory void modifyArray( int b[], int sizeOfArray ) { // multiply each array element by 2 for ( int k = 0 ; k < sizeOfArray ; ++k ) b[ k ] *= 2; } // end function modifyArray ...
I'm playing around with an Arduino UNO and a CC3000 shield connecting to a remote web service. Though I'm having a problem looping the script. As you can see in the code below, the script should ping the web service with the state ofoccupiedevery 5 seconds. Though when usingwhile(clie...

I have this project called Onionskin Vending machine. The function should be: when a coin is inserted, the pulses from the coin acceptor (which is not accurate sometimes so i didn't use attachInterrupt) is recorded by the Arduino and is shown to the user as Credits. ...
Timer1 is a 16-bit timer. In the Arduino world, the Servo library uses Timer1 on Arduino Uno (Timer5 on Arduino Mega).3. Timer2:Timer2 is a 8-bit timer like Timer0. This Timer2 is not available for ATMEGA_16U4, ATMEGA_32U4 boards, such as Leonardo, YUN, ESPLORA, etc. In the...
