E Etam New Member Jul 17, 2012 #1 I connected the I2C Sainsmart 2004 LCD to Arduino UNO directly by passing the sensor shield. And I got the error. Tried Hello World from LCD I2C Library, very simple program , but Sensor shield and direct connect gives this error avrdude:stk500_getsync(): not in sync:resp=0x30
