Regarding 2.8" TFT display

I am trying to interface TFT and Hall sensor to the programs already what we have with combining of ultrasonic sensor, stepper motor, Arduino Uno. My aim is to detect magnet material and to show the values of distance of magnet from the ultrasonic sensor in display. Can anyone tell me how? I am new to Arduino.

Take it step by step.

Can you write text to the display ? Can you read values from the Hall sensor ?

But my doubt is, Can hall sensor detect 2 meters range of magnetic field?

No. This might do it - https://www.sparkfun.com/products/10530

Also, if that is your issue, why did you title the thread about a TFT?

yeah, even all have been okay would it be possible to connect all these devices to Arduino Uno? will the pins be sufficient in Arduino Uno or other micro controller to be interfaced? Because we had too many pins for TFT?

A Mega2560 should handle it.

Could you suggest any alternate way to connect with Arduino Uno? I have Arduino Uno kit

Please provide specific pin assignments for all the devices you want to use.
