If you are using a tiny 9V "transistor" battery you should replace it with a 6-cell AA battery pack.
why would would the 6 pack work vs. the 9v?
Quotewhy would would the 6 pack work vs. the 9v?Bigger cells, greater capacity.
But what do you suppose happen with the breadboard situation? It was being powered fine with 5v.. but when transferred to the pcb it wouldnt even operate using usb/9v.
