Got the D1 Mini working.

However, one of the Wemos D1 Mini esp8266 microcontrollers is now dead. The D1 Mini, unlike the Adafruit Huzzah is not 5V tolerant.

I attempted to connect the DS18B20 with 5V logic to one of the GPIO pins.

It's fried. Luckily, I ordered two!

Also, I am still waiting out on the water pumps and the soil moisture sensors.

When they arrive, I'll integrate them.

Cheers!
