Controlling RGBs LEDs with an Arduino and Shift Registers

May 17th 2019

• Second attempt at PWM
• Debugging to this point was a pain in the neck
• It was so satisfying when it finally worked

• First attempt at PWM
• That's not quite right...

• Project Added to GitHub
• Able to control RGB LEDs through multiple shift registers
• Shift Registers output HIGH or LOW
• Limited to 8 possible colors/states for each LED
  • Teal
  • Pink
  • Yellow
  • Blue
  • Green
  • Red
  • White
  • Off
• The shift registers I have don't natively support pulse wave modulation (PMW)
• I plan to add PMW to open up the full RGB colors space
