I am working on the learning project where you capture the temperature and load it to COSM. I have the RPi set up and the code seems to be working correctly. The problem is it keeps reading the adc0 as 0 which shows as -50 C & -58 F. I have checked the TMP36 and it is reading .75 volts and I have bypassed the cobbler and wired straight into the ribbon (to check my soldering). Could my MCP3008 be bad, or am I missing something? I wired the breadboard identical to the images shown.
