I made a project using Arduino Ethernet Board, two DS18B20 Temperature Sensors and a Lcd 16×2. I used an Arduino Ethernet because i want to send the temperatures which arduino collects from the sensors to a Database (mySQL). So if you want to try this project you will need also an access to server so you can create the database and the php file. Useful Links: cplusplus.com
Hardware Required:
- Arduino Ethernet
- Breadboard
- Jumper Cables
- Temp Sensors DS18B20
- LCD 16×2
- Potentiometer 10K
- Resistor 4.7K
Wiring
To wire your DS18B20 to Arduino, connect the following pins. (I use two sensors DS18B20):
- First Sensor GND – Arduino GND
- First Sensor Vdd – Arduino GND
- Second Sensor GND – Arduino GND
- Second Sensor Vdd – Arduino GND
- First & Second Sensor Middle Pin (DQ) – Arduino Pin 8
- First & Second Sensor Middle Pin (DQ) – Arduino +5V over 4.7K Resistor
To wire your LCD 16×2 to Arduino, connect the following pins:
- Lcd Pin 1 (Rss) – Arduino Ground
- Lcd Pin 2 (Vdd) – Arduino +5V
- Lcd Pin 3 (Vo) – Middle Pin of Potentiometer 10K
- Lcd Pin 4 (Rs) – Arduino Pin 9
- Lcd Pin 5 (Rw) – Arduino Pin 7
- Lcd Pin 6 (E) – Arduino Pin 6
- Lcd Pin 7-10 – NC
- Lcd Pin 11 (D4) – Arduino Pin 5
- Lcd Pin 12 (D5) – Arduino Pin 4
- Lcd Pin 13 (D6) – Arduino Pin 3
- Lcd Pin 14 (D7) – Arduino Pin 2
- Lcd Pin 15 (A) – Arduino 3.3V
- Lcd Pin 16 (K) – Arduino Ground
- Don’t forget to connect and the other 2 pins of potentiometer to Ground and +5V.
Interesting! I need to test this way!
good very good I hope from you another programs
Where is the rest of the info about this project? I don’t see hardware connections or code here, is the link maybe missing? I am working on something similar and would love to see how you implemented all this.
Thanks,
John.
I need to learn to connect from arduino (esp 8266) with data tables process variables in SQL Server, which I can explain the steps. The idea is to control the web, SQL Server would link arduino and asp.net. Thank you very much, God bless you
