just an update.. i have my pid system working fairly well just needs a little more tuning..
now i'm looking for some extra credit.. bought an lcd and got it hooked up and running to display temp and power output front the heater.
also planning to get a photoresistor to turn the backlight on and off.... and throw some leds in the tank with some sort of fading effect
at first i was just doing this arduino thing because it was for school.. but its alot of fun.. can see myself spending alot more money on it..
after my presention on saturday will upload my code... its super basic, but i will welcome and advise to imprve it
