After many months of trying to teach myself how to write a program for a pic micro to control the temperature in my greenhouse propagator I must, with reluctance, admit defeat.
I would be grateful if any elektroda member could design a circuit and write a program to control the temperature in two different zones between approximately 15ºC and 30ºC and display the current temperature in these zones on a single LCD.
A means of setting the temperature would be necessary.
I would prefer the circuit to use thermistor beads for the sensing element (so that the sensor could be placed in the seed medium at seed level).
Also I have seen vivarium thermostats which use pulse-proportional control and would like to use this if possible, to prevent large hysterisis.
I am prepared to pay a small fee to anyone who can help.
