Hello! I have a query, I want to connect 13 buttons, a 3.5 display, 16 rgb2812 leds and 4 rotarys.
Leo bodnar plates are not available in Argentina, you would have to use a usb zero delay or something like that. I wanted to know if I can use an arduino to connect the display with the corresponding connection:
GND => GND
VCC => 5V
RX1 => TX
TX0 => RX
and at the same time use the arduino to connect encoders, leds or buttons.
I would need to use 2 arduinos I can think of, in one the 12 buttons and the LEDs for example, and in the other the encoders and the panel.
If not, you would have to use a TTL adapter for the panel, and separately 2 arduinos to connect the LEDs, encoders and buttons.
I wanted to know what you can recommend me because I am totally amateur in this matter.
From what little I understand, I would have to use 2 arduinos pro micro for it to recognize both the buttons, encoders and LEDs:
My question is if at the same time I can connect it to an arduino (to which it does not use the LEDs so I have no problems with current) the display so I don't have an extra usb connector.
Another query, is if I connect 2 arduinos and the usb tll adapter at the same time to a hub, I have no problem with that.
Thanks and best regards, Guillermo.
If for some reason someone speaks Spanish and answers me in Spanish. no problem that is my native language, for English I use the google translator
