But I couldn’t get the blink program working with the ESP8266 interfaced with the Arduino. It looks like a level shifter and power supply is needed to make it work correctly and I’m not that good at soldering. So, that is why I was looking at this “D1 WiFi UNO Based ESP8266”. If that doesn’t require level shifting and a separate power supply I’d like to try that route. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Right now I have a Raspberry Pi recording my hot water heater on and off in a mysql database and I’m using the SSH to watch the data on a second Pi via WiFi.
