I should probably tell you more about the project.
So I am a physics student on a 2 month internship with a small company working as a solo research and development team. The company makes washer disinfectors which clean toiletry utensils for places like hospitals and care homes. They gave a a very broad design brief to incorporate more technology into their machines which are mainly controller by fixed circuit-boards and relays and stuff (I don't really know circuitry well). So I was told they were looking into using a raspberry pi to control their whole washing cycle so I have been learning linux, node-red, javascript to help me use it ( I previously only knew python).
So where I am at now is I have built the bare bones of the system which basically turns individual LEDs on to represent the switches to turn on pumps and steam generators needed throughout the cycle. I though I could get rid of most of the physical buttons and temperature gauges they used for a touchscreen as that is way easier in node red dashboard.
So actually moving onto your question I am not sure what I'll need yet in terms of powering the touch screen as the panel I have now you need to slot in the pins of the pi to the back of the screen in order to be able to use the touch functionality. This isn't ideal for me as the temperature probe I have needs to use some of the pins which the Screen is now taking up. So now that I know I can start the dashboard can start up on the screen without too much of a hitch. I can now look for screens which done need to use the pins to be touch compatible. I think in either way the screen will be powered by the pi, but there is another power port on the screen i have. Is it a good Idea to plug in two power sources?
Sorry for the long story
