Introduction: Time and Temperature With LCD and Arduino (FIXED)
My name is Samuele, I'm 14 and I come from Sicily...I'm a new entry in Arduino's world!
I have already some experiences with electronics and DIY project, but I started to write some programs on Arduino to simplify my works.
This is my first Instructables project, so you may not well understand me...it's because of my little experience but (maybe) of my english too!
Now let's get start!
Step 1: Materials
To make this project you'll need :
3 potentiometers [or 2 pot and 2 push button];
1 push button;
1 2.2k(or more)ohm resistor;
DHT11 (temperature and humidity sensor);
DS3231RTC (Real Time Clock);
Step 2: Schematics
My initial purpose was to make a simple digital clock with temperature and humidity datas so...I made it!
I had some difficulties in the schematics too, because there are a lot of cables!
Maybe my schematics are very confused but there's no problem...I wrote them for you :
LCD (16 pins)
pin 1 - gnd
pin 2 - 5v
pin 3 - 1st potentiometer pin (connect pot to ground and 5v)
pin 4 - Arduino D12
pin 5 - gnd
pin 6 - Arduino D11
pin 11 - Arduino D5
pin 12 - Arduino D4
pin 13 - Arduino D3
pin 14 - Arduino D2
pin 15 - 2nd potentiometer pin
pin 16 - gnd
1st pin (right)- Arduino A3
2nd pin(middle)- 5v
3th pin(left)- gnd
SDA- Arduino SDA pin or Arduino A4
SCL- Arduino SCL pin or Arduino A5
Other components :
push button to Arduino D7
3th potentiometer pin to Arduino A0
I added a reset button too....just take a push button and connect it to gnd and Arduino RST pin.
Step 3: Now the Code!
Let's upload the code
You can find it here :
Step 4: We Finished!
Now we can see the code running!
