Simple Pressure array

Projects General Guidance
1

Hello,

I would like to ask you for help to create a very simple pressure measuring array formed by four pressure sensors and Arduino Uno. Let's assume four pressure sensors are aligned to form a 1D array. I think I could even use the black packaging rubber used for electronics to create my four small sensors: pressure would change the resistance of the foam.

How would I connect the four small sensors to Arduino? I would like to measure and record in real time the pressure applied to one of the sensor or the pressure from multiple sensors at the same time. How do I need to configure Arduino to be able to store the data coming from multiple sensors at the same time?

Thanks!

Thanks Delta_G.

I guess I would need an analog pressure sensor which I would build using that black conductive foam. Once I build 4 of those pressure sensors, I would run wires from each one of them to the analog ports of the Arduino. Is that correct? But it would be an issue if I had 10 sensors (not sure there are 10 analog input ports on the board)...

How do I connect the SD card to the Arduino? Is it easy? I am not looking for specific steps but trying to grasp the general, high level idea of how to do this project...

Thanks,
Fused
