ALL CAT 5 AND CAT 5E AND CAT 6 ETC IS ALL TWISTED PAIRS AND SHIELDED. SOLID WIREIF IT WASNT THE NETWORK CABLE WOULD NOT WORK OR RUN AT 1MBS
Ive always read you should always include resistors not just to protect the LEDs bit the Arduino board as well. Just sayin
When you say switches. Ive been looking for months now to have a system that will control (turn off and on or flash 3 to5 different sets of LEDS In otherwords. One Piezo trigger and One set of 12v lights flash when struck. Anybody got anything?
