Hello Guys,
In this step by step instruction,
I want to share my experiment on creating a clock and thermometer with
Arduino Mega 2560, LCD 16 x 2, thermal resistor sensor and DS1307 real time clock

Prepare all the needed materials :
1. Arduino Mega 2560
2. LCD 16x2
3. RTC DS1307 module
4. NTC ( Negative Temperature Coefficient ) thermistor
I used 10K with lug
5. USB cables for PSU, you can use your own connector too...
6. Some male to male breadboard wires
7. Some female to female breadboard wires
8. 10 K 1/4W resistor
9. 1 K Trimpot
10. Arduino compiler, you can find it on arduino website
I used Arduino 022

Step 2: Connect your arduino to LCD,RTC and NTC

Here're the connection list to Arduino Mega 2560 for this project :

* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground

* ends to +5V and ground
* wiper (1K Trimpot) to LCD VO pin (pin 3)

RTC module :
connect to pin
pin 20 Arduino = pin SDA on RTC module
pin 21 Arduino = pin SCK on RTC module

Thermistor connection :
connect thermistor to A0 on arduino board series with 10K 1/W resistor.
Please see the schematic for thermistor

Hi Arick,

Would you provide a download link for the DS1307 Arduino library, which you use?. I have found a lot of versions and implementations, but I would like to try with something which is proven on Arduino Mega 2560.

Best Regards
Milen
