Pressure Control Using Arduino

About: Trust me, I am an engineer.

This is my first arduino project which i had completed as a project for my university. This project is supposed to be a model of the air pressure control unit available in the airplanes.

Step 1: Parts

You will need to get these parts before starting:

1. Arduino Uno

2. 16*2 LCD

3. Wires

4. Solderless Breadboard

5. Air pump and valve. ( i got both of them from an electrical blood tension monitor. )

6. Transistors ( i used 2N2222 and 2N3904. )

7.batteries ( i connected 4x 1.5 batteries in series. )

8. BMP 180 sensor

9. 2x 10K resistors

10.Leds

11.Manual Tension meter

Step 2: The Circuit

The connections in the picture are pretty clear aside from the missing ground and power pins of the sensor which are to be connected to the ground and the +5V pins of the arduino.

I also had included a manual pressure pump and valve as shown in the picture which are not included in the electrical schematic (since they are not electrical :) ).

The sensor is to be placed in the air vessel of the meter unit ( you can use your own vessel ). along with its own air cables and the cables of the electrical pump and valve. the rest is pretty standard stuff.

Step 3: The Code

You should download the sensor library for the code to work properly, the link for the library:

Step 4:

The function of the code is explained in this video. After this you are good to go ;)

    Thanks for the advice, but it appears that since i am a resident of Turkey, i am not eligible for the contest..... which is kind of silly.
