When using sample_train i get the output : `train-------------------------------------------------------------------------------- Command Format Error! -------------------------------------------------------------------------------- clear -------------------------------------------------------------------------------- Clear recognizer failed or timeout. -------------------------------------------------------------------------------- ` When using sample_control_led for simplicity the connection it is not recognised. Output: `Elechouse Voice Recognition V3 Module Control LED sample Not find VoiceRecognitionModule. Please check connection and restart Arduino. ` it is failing the ` if(myVR.clear() == 0){ Serial.println("Recognizer cleared."); }else{ Serial.println("Not find VoiceRecognitionModule."); Serial.println("Please check connection and restart Arduino."); while(1); } ` check `myVR.clear() == 0` is not being fulfilled please help
