I am trying to connect GY-521 to Arduino UNO board with the following setup :
VCC - 5V GND - GND SCL - A5 pin SDA - A4 pin
However, I cannot make a connection between GY-521 and UNO board.
I,ve tried to seach the error with I2cScanner program, but gives the following result :
I2C Scanner Scanning...
Using Gy521_send_serial or GY-521-Dev-Kit (https://github.com/janaka/Gy521-Dev-Kit), before calling endTransmission(), the Serial print works well. However, after calling endTransmission(), the Serial print doesn't work at all. The printed result is
InvenSense MPU-6050 June 2012
Please let me know why the GY-521 doesn't give any reponse after calling endTransmission(). Is there anybody who experience the similar situations?
