I bought five digital sensing boards from ebay, marked Keyes on the board and Dallas 18B20 on the chip.
When I run the hacktronics sketch to find an address, it returns that no address is found. I have the power pins hooked as indicated on the board (and a red LED comes on) and the signal to digital pin 3 as in the sketch (attached). Am I doing something wrong, or could all five of these be bad? Thanks.
