and then from 180 to 0 degrees. To set the shaft to a particular position, you just need to use thewrite()method on theServoobject. You pass as an argument, an integer number with the position in degrees.
First we have to define the Trig and Echo pins. In this case they are the pins number 9 and 10 on the Arduino Board and they are named trigPin and echoPin. Then we need a Long variable, named “duration” for the travel time that we will get from the sensor and an integer variable...

float parseInt() Description 从新到的串口数据中查找下一个有效的整数 Looks for the next valid integer in the incoming serial stream. parseInt() inherits from the Stream utility class. In particular: Initial characters that are not digits or a minus sign, are skipped; Parsing stops when no...
The first value is the data type (0=byte, 1=16 bit int,2=32 bit int,3 = float). The second parameter is the position in EEPROM, the value is stored. The third parameter is the current value. The rest of the line is a short description of the parameter....

This variable should be set to the base-2 logarithm of the number of microseconds per OS tick. The default is 4, which indicates that each tick corresponds to 16 microseconds (because 16 == 2^4). Setting the SPI-bus frequency #define LMIC_SPI_FREQ floatNumber ...
