Hi everyone!

I am completely new to this, and chose this as my first project.
Probably should have started with something more simple...

Anyway, this is a bit more that a project, is something that I realy need working...

I bought all the parts, download everything and know I am getting some errors when compiling the sketch.

Highlithed in yellow is the lines I am having problem with...
The first one says:
error: 'DHT22' was not declared in this scope - This should be only to identify the sensor type inside the DHT library.
However if I include the DHT22 library the error goes away.

Then the next one says:
error: expected primary-expression before ')' token - I don't have a clue how to solve this one...

There is some more, but one at the time... LOL

/*DHT.cpp has an default delay of 250. This makes the system realy slow and must be adjusted to 50 to react faster
Hardware used:
Arduino uno
Ethernet Shield W5100
DFRobot LCD Keypad Shield
DHT22 Humidity and Temperature sensor
2x 2 channel 5v relay

_____1 Room Thermostat pin 2
Relay 1___2/ Heater pin 2
_______3 Relay 2

_____1 Mot Connected
Relay 2___2/ Relay 1
_______3 Heater pin 1 and Room Thermostat pin 1

#include <LiquidCrystal.h>

DHT dht1(DHTPIN1, DHTTYPE);
DHT dht2(DHTPIN2, DHTTYPE);
const int System = 2; // pin connected to relay 1
const int Heater = 3; // pin connected to relay 2
const int Buzzer = A5; // pin connected to buzzer

float Td; // disired temperature
float h1;
float h2;
float t2;
float Tt;
int softwareversion = 1191;
int address = 0; // eeprom address

If anyone can help will be much appreciated!
Thank you in advance!

You need to download the LiquidCrystal and EEPROMEx library's. but i suggest you use the new beta version. it is easier to install and much more stable, I use it for more than a year now and never had problems. It doesn't come with the LCD but that's what the phone is for :slight_smile:
