I just purchased the ThunderBoard I2C Lightning Detector with Grove Connectors and I'm using an Arduino uno r3 wired thusly:
ThunderBoard -> Arduino
================
SCL -> A5
SDA -> A4
VCC -> 5v
GND -> gnd
INT -> Nothing
When I plug the Arduino in, the INT LED light on the ThunderBoard lights up white, and stays lit. When I run the I2C scanner, it just stops and never returns from the Wire.endTransmission(). Any help would be most appreciated!
Thanks,
Steve

What I2C address are you using on the Arduino? Try the example software too.

The address is whatever the board defaults to, but the I2C scanner doesn’t ever even find the board. The scanner just stops and never returns.

Run the ThunderBoard demo software and see if the ThunderBoard responds. Check the software to make sure it is checking for the 0x02 I2C address.

I downloaded the I2C library and the SDL_Arduino_ThunderBoard_AS3935 demo software from github.com/switchdoclabs/SDL_Arduino_ThunderBoard_AS3935. The demo s/w is using 0x02, and when I run it, it never returns from AS3935.reset(). I also tried the I2C scanner you posted for JimK on the forum (http://forum.switchdoc.com/thread/810/lightning-detector-simulator-working-arduino), and that never returns from the first Wire.endTransmission() call. It seems the ThunderBoard just isn't responding. Your thoughts? Thanks, Steve |

What happens when you disconnect the Thunderboard and run the i2c scanner software?

With the Thunderboard disconnected, the i2c scanner completes the scan, reports that it finds no I2C devices, and repeats the scan every 5 sec. When the Thunderboard is connected, it never returns from the very first call to wire.endTransmission(). I replaced the Thunderboard with another I2C device I have, and it finds that properly.

You have a bad ThunderBoard. Thanks for the information.
Where and when did you buy it?

That’s what I figured. I bought it from Switchdoc Labs through Amazon.com, ordered June 17. Amazon says I can return it until July 18. Should I go through amazon, or ...?

Going through Amazon gets you free return postage, so I would suggest that.

 No. I get the same result on three different brands of Arduino Uno boards, even a genuine Arduino. I'm not sure what to try, so any thoughts? Steve

srr58,
Post a close up picture of the board and let me get a look at it. I'm clueless at this point.
What is the result you are getting? You know this is at address 0x02 don't you? And you should be using AS3935 software to test the board, not an I2C scanner.
