I am using protoboards for the first time, and I can't seem to get the circuits I am making on them to work. I would have no problem getting these circuits working on a breadboard, but for some reason (bad soldering?) it's just not working on the perfboard.
This is a pretty simple circuit I am trying to make using a Teensy 3.2 Arduinolike microcontroller. It uses four push button switches, each of which have a pin connected to the same ground line. This ground line is connected to one of the outer pads on the protoboard. There are four wires each connected to a pad and to a switch.
I then connect the ground pad to the negative rail on the breadboard by Teensy is sitting on, and connect each of the four wires to a data pin on the Teensy. I then run code that detects each button press, however none of the buttons are working. Any ideas just from my pictures on why I am not getting any connections? Do the external pads on the protoboard not conduct on either side of the board?
I won't have access to a multimeter until tomorrow.
