// **PARTS required (for this sketch to work as it is )
//**********************//**********************//**********************
1.Arduino Nano
2.A thermistor (i used A 10K WATERPROOF ONE)
3.A resistor (matching the value of the thermistor's "nominal resistance at 25 DEGREES C" for example: 5k resistor for 5k thermistor)
4.OLED display ssd1306 (mine is ssd1306 but got it working by using sh1106 constructor also got rid of the "white line problem")
5. DHT 22 (WITH PULL UP RESISTOR I USED 10k OHM)
6.RELAY MODULE LOW LEVEL TRIGGER TYPE (5 Relays required in total for all the pins, can be seperate 4 CAN WORK TOO )
7. DS3231 RTC MODULE (RESISTOR from charging circuit REMOVED and charging DISABLED..BECAUSE I USED CR2032(NON-rechargeable)Cell
8. AN LED WITH APPROPRIATE RESISTOR FOR USING AS A STATUS LED
9. An ESP8266 / Wemos D1 / Node Mcu
If you to want to monitor it Wirelessly using a 3.3 V Esp8266 with a 5V Arduino then Two Resistors
one 1K Ohm and one 2K Ohm . Using these two resistors make a Voltage Divider Circuit by connecting
the Tx pin of Arduino to the 1K Resistor then on the other side of the 1K Resistor join the D1 pin(Rx) of Esp8266
and at the same point join the 2K Resistor and then the other side of the 2K Resistor to the Ground
The Ground Pin of Arduino and Esp8266 will also be joined together Directly
Sketch for the Esp8266 is on the blog

// Five pins used which have to be connected to five relays(optically isolated for eliminating interference)
// usually a 4 Relay board is available so it can be used as only one of the pins for Heater/Cooler are required
// and they can be swapped according to the outdoor temperature in different seasons
// TO optically isolate them properly Two separate power supplies have to be use
// one for Arduino and one for the Relay board
// the relay board has a Removable Plastic Jumper connecting JDVCC-VCC pins, it has to be removed
// VCC pin on the Relay module is connected with the power supply one that powers Arduino
// the VCC on the Relay module powers the opto-isolators and the leds
// the In1,2,3,4 on the Relay board will be connected to Arduino's GPIOs and when the corresponding
// GPIO's are turned LOW and that Opto-Isolator will then turn ON because the In 1,2,3,4 pins are Ground pins
// for those four Isolator chips on the Relay Module and the Arduino Connects them to the Power Supply one's Ground
// To which the Arduinos Gnd pin is connected too
// Now the JDVCC pin and the Marked Gnd ground pin on the Relay module will be connected to the Second Power Supply
// and it will only power the Actual Relays on the Relay module
// it means the marked Ground pin on the module will not be connected to Arduino
// the only pins of Relay Module that connect to Arduino are VCC,IN1,IN2,IN3,IN4
// LOW-level Relay board will trigger the relay when the trigger pin is LOW/off/grounded
// so when something has to be turned ON the trigger pin ( example IN3 ) will become LOW otherwise
// it will stay HIGH (asamf) all the time during which the thing is required to be "OFF"

Keep getting "Error compiling for board Arduino Nano". what do i need to change?
ReplyDeleteSorry for the late reply but i test my code before posting it on the blog and after posting it i copy it again and i compile it to avoid such issues .. i have just tested it again i am not getting any errors it compiles and works. I have Arduino IDE 1.6.9 maybe you have different version or did some mistake while copying ?
Deletealso make sure you have all the libraries installed and correct versions in the IDE go to Manage Libraries and type names of Libraries in Serach box and see if all the libraries are installed and their versions too
