Hello Guys,
i'm looking for a touch screen for arduino uno r3. But i would also like to additionally use one analog pin for a sensor and one digital pin for a relais. Is there a touch screen, that would fit in my situation?
Thanks in advance

The Red 2.4" Mcufriend shields allow A5 for Analog. D10-D13 for digital if you are not using the microSD.
If you buy a Chinese Uno clone with SMD mega328 chip, you can use A6, A7 for analog and A5 for digital. And still use the microSD.
