Finally got back round to doing a bit work on this project,

-Firstly got an arduino setup with sd card logging some numbers for my soil moisture sensors. hopefully should have enough data this week so i can finally add the watering pumps.

- Been working on the outputs for the fans made so good progress they seem to be ready for an actual test, when i get round to building an enclosure.

The next lot of pictures are the LED outputs for the temps. i have a RED, ORANGE, And BLUE for each temp sensor. RED = Too Hot, ORANGE = Perfect temp, BLUE = Too Cold

At the moment if one temp sensor is above 23C and the other is below 21C an internal fan will start (2nd RED LED) to bring both temps back in range. If both sensors go above 23C an external fan (WHITE LED) will start until both temps are back in range.

Ive also tidied up whats on the display so it will output the fan states.

Here the temps are within the set range so no fans on

Here both temps are above 23C so the external fan output is on.

Here the temps are different so the internal fan is on.

Heres my serial out put.
