Tell us about yourself!
Hello thanks for the reply, it was me I mistakenly set a pin as the same pin that one of the relay was using. Up and working with temp sensor. Now I just need to assemble the rest of the parts and test again. Thanks so much for sharing.
I assembled the LCD screen, Arduino, and one DHT22 to test and screen comes on shows graphics that's its suppose to for a second then goes all white. If I reset I get the same thing. Any suggesting on what might be going on? If I apply a different code to test the LCD, it works fine so I know the LCD screen is good. Any help would be greatly appreciated.
