Hi there,
i want you to help me deciding what board i may use for my new project. here is the list of features i will ask the arduino board:
1x Step-motor
1x DC motor
10x leds
10x switch buttons
1x old screen
my doubt is about what board using, but also if it will be necessary to use 2 boards in the same project, please, clear my doubts, thanks a lot
Have a nice day
Nobody can tell you, as you don't say what you want to do.
you need to total up your IO requirements, e.g. to interfacing modules such as OLED display, stepper motor, DC motor, etc can often require several pins - also consider how you will power the system
what extra functionality may you require in the future
have a look at esp32-pinout-reference-gpios
avoid having to use two boards - having to program two microcontrollers and the resultant communications makes the overall task complexity an order of magnitude greater
to add more GPIOs you can always use IO extenders
Thank you Horace,
i was looking at Mux or Multiplexers, i suppose that is what you mean as IO extenders...
i do understand that one board is better than 2, ...
thanks for the links, very useful!
The last point about the power supply will be for a new topic on the forum, but yes, that will be the tricky part.
