Hi guys,
I bought in last few days Arduino MEGA 2560 board and Arduino shield with buttons and LCD (16x2).
Pins on shield were already soldered, which was great at first, but then I realized that I can't connect 3v3 voltage supply from Arduino board to my IR sensor (it mustn't be applied to 5V). Then I saw holes next to those pins.
My question is:
Are those holes connected to those pins (to be precise look at the image in attachment marked with red)? If they are, can I solder just one extra pin to that hole?
Maybe it's a stupid question, but I need to be sure, because I want to avoid protoboard, lots of cables and so on.
Thanks!
