Addressable LEDs

ArduinoBuild

This build uses RGBW Addressable LED strips. This means that the strips have 4 diodes: red, green, blue and white. Each diode uses 20 mA of power, so 80 mA per light.

You can purchase these components from a lot of different retailers. I prefer Adafruit over Amazon because I have never received a broken part or a clone. 

Required Supplies:

  • RGBW Addressable LED Strip - 30 per meter - $17.95/meter - Found at Adafruit
  • Arduino Uno - $24.95 - Found at Adafruit
  • 22AWG Wire - $2.95 - Found at Adafruit - I recommend 3 different colors.
  • 1000 uF Capacitor - $2.09 - Found at Amazon
  • 470 Ohms Resistor - $5 / 100 - Found at Amazon
  • Solder - $11.95/ 50 grams - Found at Adafruit 
  • Cheap Soldering Iron - $19.95 - Found at Lowes - My Soldering Iron - $98 - Found at Amazon
  • Power Supply - This depends on how many LEDs you will be using. I would not recommend going over 6A because this is the maximum recommended current for 22AWG wire. When you buy the power supply you will have to cut off the connector to access the positive and negative wires. Normally, power supplies with barrel connectors will have the positive and negative wires separated.
    • 30 LEDs - 5V, 2.5A power supply found at Amazon
    • 60 LEDs - 5V, 5A power supply found at Amazon
    • 100 LEDs - 5V, 6A power supply found at Amazon - Please note that you would have to run the LEDs at 75% brightness.

 

Optional Supplies:

  • Molex Microfit Connector Ultimate Kit - $56.75 - Found at Inventables. Definitely overpriced.
  • Crimping Tool - $22.00 - Found at Inventables
  • Heat Shrink Variety Pack - Found at Amazon
