I need to connect the following devices to an Arduino UNO board. The problem is that I run out of pins to be able to connect them all. Is there any way to do it?
I'm doing the project in Tinkercad
In the picture below I tried to do it, but I am missing 2 pins for the ultrasonic sensor trig and echo
As cguck70 already stated in the comments: The pins A0 to A5 can be analog input pins, but they can also be normal digital input/output pins. You can use them to your liking, just like any other digital input/output.
So just connect two of these pins to your ultrasonic sensor and use the pin names A0, A1 and so on in your code.
