Hi ll.

I am beginner in arduino. I want to know how to control 3 sensor using one arduino? is it possible? thank you

Almost certainly, but for absolute certainty you should post details about what they are.

They might for example need 20 wires each and produce signals at 100V which would be a "challenge".

The exact "how" will depend totally on what those sensors are, so we need detail to help you.

Thanks for your reply JimboZA.

My first and second sensor is pressure sensor while the third sensor is temperature sensor. Each sensor have different coding. Before this I code separately for each sensor. And now I want to combine the coding and control using one arduino. How to do that?

Well in principal you do this:

  • Make sure you have no pin conflicts, and make sure you change the final sketch to reference the right pins
  • Put everything from above setup() from each sketch into a new sketch above its setup()
  • Put everything from each setup() into the new sketch setup()
  • Put everything from each loop() into the new sketch loop()
  • Tidy up, eg maybe consolidate the digitalRead()s and analogRead()s together, the Serial.print()s into one neat part

But that's in principal: the specifics will depend on your existing code, the actual sensors, and the wiring.

What have you tried so far?
