int c_button = 0; // byte nunchuck_buf[5] contains bits for z and c buttons // it also contains the least significant bits for the accelerometer data // so we have to check each bit of byte outbuf[5] if ((nunchuck_buf[5] >> 0) & 1) z_button = 1; if ((nunchuck_buf[5]...
int checkSensor(){ //这儿定义了一个整数形函数checkSensor if (analogRead(0) > 400) { //如果读取0针脚的数据大于400的话 return 1;} //返回1,相当于调用这个函数后得到的值是1 else{ return 0; //返回0,相当于调用这个函数后得到的值是0 } } return关键字可以很方便的测试一段代码,而无需“comme...
6、更改I2C地址 要在调用compass.setADDR(BYTE_VALUE);之前更改I2C地址呼叫,compass.init();如下所示: 1 2 3 4 voidsetup(){ compass.setADDR(BYTE); compass.init(); } 7、更改模式,数据速率,比例,采样率 您还可以更改QMC5583L芯片的模式,灵敏度,采样率和输出率。等等,只需在调用compass.setMode(MODE, ...
S 3) Start the Arduino IDE and check if you have the menu-entry "File > Examples > tvout". If not, restart the IDE and check if you put everything in the right place. Things to do with hardware/your Arduino: TV-Connection
In the Arduino IDE, and other C-like programming languages, every statement is ended with a semicolon (;), as you can see in this Blink example. When you get cryptic errors when trying to upload, one of the first things to check are the semicolons. Most of the times, you'll get ...
Check if a packet has been received. int packetSize = CAN.parsePacket(); Returns the packet size in bytes or0if no packet was received. For RTR packets the size reflects the DLC field of the packet. Register a callback function for when a packet is received. ...
Binary sketch size: 1092 bytes (of a 14336 byte maximum) If that works, you’ll see the LED on your board start blinking, and you’re ready for the next section. If it doesn’t, your controller is probably not connected properly. Check the settings for your controller and the port in...

I am using a premade voltage divider and a premade LED that has the resistor built in. Arduino Sketch Like the circuit, the sketch is fairly simple. It basically repeats the following; check for received data, check the received data for either a “0” or a “1”, ...
