First I had a software problem. Solved that but now have a hardware problem
http://www.electroschematics.com/9809/arduino-8-bit-binary-led/The sketch loads fine but the counter doesn't run - no LED action whatsoever.
As shown in the image I didn't exactly follow the breadboard instructions but I can't see what the problem is. One symptom is that the resistor near the button is somewhat warmer than I would have expected.
I'm betting it's something pretty obvious and goofy....
Any suggestions? Thanks!
Update: I turned the button 180 degrees and now the first LED lights but the button doesn't seem to advance the counter. The resistor near the button is still overly warm. (I know I used 200 ohm resistors instead of 220 ohms but I'm doubting that is the issue.) I'll try substituting another button just in case it's a button defect.
Update: tried another button and noticed that when I plugged in the new button the LED counter advanced - but pressing the button didn't advance the counter further. So I removed the button and just manually jumpered the on-off with a wire touch to the breadboard and it advances the counter. Pretty sure I just have a wiring issue with the button.
Update: figured out how to rewire the button. Counter is advancing as intended.
