Im connecting raspberry pi to arduino through i2c. It worked fine but suddenly it stopped working and I am afraid something have happened to the arduino.
I have connected:
(Pi) SDA -> SDA (Arduino)
(Pi) SCL -> SCL (Arduino)
(Pi) Ground -> Ground (Arduino)
But when I am running
sudo i2cdetect -y 1
suddenly it returns blank:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

When I am connecting another sda device to the pi it however gets detected so there is nothing wrong with the pi.
Is there a possibility I can have fried the arduino?
It however gets detected and I if I upload a simple sketch to it for blinking it works with no problem. It is just the i2c who doesnt get detected anymore
