Serial.print(数据,数据的进制)如果没有指定,预设以一般文字传送。 范例: Serial.print(75); // 列印出 "75" Serial.print(75, DEC); //列印出 "75" Serial.print(75, HEX); // "4B" (75 的十六进位) Serial.print(75, OCT); // "113" (75 in的八进位) Serial.print(75, BIN); // "100...
And now, we need to manipulate the servo motor. As you recall, the cloud variableservo_positionis used for this. This is where the callback function that the Arduino IoT Cloud wrote for us comes in. Remember, it is called every time the cloud variableservo_positionchanges. So, all we n...
