while循环 while循环将会连续、无限循环,直到括号()内的表达式变为false。必须用一些东西改变被测试的变量,否则while循环永远不会退出。 do…while循环 do ... while循环类似于while循环。在while循环中,循环连续条件在循环开始时测试,然后再执行循环体。 for循环 for循环执行语句预定的次数。循环的控制表达式在for循环...

While the Si4735-D60 provides the 0x11 I²C bus address when the SEN pin is connected to the ground, the SI4732-A10 provides the same address when the SEN pin is connected to the +VCC. Also, this library provides the functiongetDeviceI2CAddressto detect the I²C bus address automati...
Product Overview This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers ne...
This might seem like a big deal at first, but you’ll realize after working with Arduino for a little while that the types of things that you do with Arduino don’t require strings or text as frequently. If you do need to work with a String class, you need to make an array of ...
Compare this to the Serial call and response example. They are similar, in that both use a handshaking method, but this one encodes the sensor readings as strings, while the other sends them as binary values. While sending as ASCII-encoded strings takes more bytes, it means you can easily...
