the code you posted can not be compiled it seems to have skipped parts like
lcd.print("Adjust
and
lcd.print("0
also if you can post where you downloaded the rtc library that would be helpful
if you have the C being displayed on a lcd then some where in your code you are using something like
lcd.print(t,1);
means you are printing t which is the name assigned by the dht library as in float t = dht.readTemperature(); as its a float by adding the ,1 it shows 99.5 (1 digit after the...
depends on which sensor you are using. You can use a simple sum to convert F to C if the senor code doesn't already have that option.
convert C to F
Multiply by 9, then divide by 5, then add 32
In arduino make sure you use brackets so the sum is done in the order you want it rather than...
we used both this and split molds in school but I always presumed that you required a special sand to hold the shape as the Styrofoam was melted by the aluminum heading to the bottom of the piece. If damp play sand works then copying your smelt is going to be my next project. No idea if they...
Shouldn't be a problem to program the mister to run for a short burst then wait 3-5 minutes to check the humidity before deciding if it needs to run again. I use a separate chamber that holds water and when the humidity drops then air is sent via the chamber to pick up moisture and that works...
knex (kids toy) has some carousel gears that are about 5" in diameter and maybe a piece of 4 inch pvc drain pipe would be big enough to make a incubator (its can be bent and modeled if heated).
how about any small dc motor that's gear reduced and a few prox sensors or ir beam sensors (few bucks each for arduino) then turn the whole incubator like brimasea does.
I built my incubator about 6 months ago using a arduino mega and dht22 and that's still running good. I used a rtc (real time clock) that cost about $2.
For the turner I used a geared motor as a servo has to hold the load where a angle drive holds it by the nature of its design. I did go a...
