• connected launchpad
• 3 RGB LED stripes (common +)
• MOSFETs: IRL540N
• Schaltung ist wie beim Ingress-Table: https://github.com/c-base/ingress-table#led-driver-circuit
• PWM-PINs in RGB-Dreier-Gruppen:
  • erste Gruppe: PM_3, PD_1, PD_0
  • zweite Gruppe: PL_4, PL_5, PM_1
  • dritte Gruppe: PM_7, PA_7, PM_6
• Pinout siehe: http://energia.nu/img/EK-TM4C1294XL.jpg

• Sourcecode uses energia: http://energia.nu/
