I found this code on another website that works for me. It reads the temperature and sends me email alerts. I'm trying to get the code to send me a email every morning at a specific time. Im time and timealarm to accomplish this. I getting a error saying 'alarm' does not name a type. Could someone help me out. Thank you.
