lukas412 Posted February 1, 2012 Report Share Posted February 1, 2012 (edited) I assume the voltage at the led's on Wilba's sequencer pcb will be 5 volts but want to double check to be sure. I just want to test some various resistors to get the right brightness before I solder.

kHz-tone Posted February 1, 2012 Report Share Posted February 1, 2012 (edited) Do not solder resistors to PCB, use sockets, so you can test different values. cheers Philipp Edited February 1, 2012 by kHz-tone Quote Link to comment Share on other sites More sharing options...
findbuddha Posted February 1, 2012 Report Share Posted February 1, 2012 Yes, 5 volt, but make sure you test using the PCB (not just a breadboard) as the matrix wiring reduces the brightness a bit. Quote Link to comment Share on other sites More sharing options...
