把第三行的0*27改成0x27
你好，你最后是怎么解决的，谢谢
Arduino:1.7.2 (Windows 7), 板：&Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)&构建选项已变更，全部重新构建sketch_apr17a.ino: In function 'void setup()':sketch_apr17a.ino:7:3: error: 'servo1' was not declared in this scopesketch_apr17a.ino:9:3: error: 'servo2' was not declared in this scopesketch_apr17a.ino:11:3: error: 'servo3' was not declared in this scope编译有误。
