Hi @Yogurt_Man and @WaldoPepper , thanks for responding!
I tried connecting my OpenCR9.04 to a 7.4V supply as in the image you sent but no change… I also read through the “id” example but I don’t think I can set any IDs without first having them recognized.
I did also set the preprocessor lines in the scan example (and others) as you suggested @Yogurt_Man (will paste that example to confirm I understood) but again no change.
Any other ideas? May post to the arduino forum too perhaps.
Thanks again,
Sean
