2.8" TFT Touch Shield as a Speedometer
I've been thinking to use this shield to use it as a speedometer for my bike, but I need, at least, 3 pins to use measure the speed...and I am not sure how to wire the Arduino using this shield.
Please, can you tell me if you have done something similar? For example, to connect sensors to the Arduino and use this shield to show the values....
Do you think that could be a good idea for my project?
Thanks in advance,
