VARIATIONS

• I've been asked to create more and I changed ingredients and made the flowers my self with the origami technique.
• Here are their pictures: VARIATION#2 - VARIATION#3 - VARIATION#4

• Do you want one? Send me an e-mail b.sansone[@]headroom[.]ws (please delete antispam square brackets in your mail client) to order one
• ... or we can exchange something via F.A.M. (site in spanish)

INGREDIENTS

• 1 ARDUINO USB
• 1 DIFFUSED LED RGB
• 1 POWER SUPPLY 12V=/1A
• 1 BIG WHITE PAPER FLOWER
• 1 SMALL BOX
• 1 TELEPHONE CABLE (4 wires inside)
• A SMALL PIECE OF PERFBOARD
• A SOLDERING IRON
• SOLDERING WIRE
• THERMORETRACTABLE COVER
• SOME PIN-CONNECTORS
• 3 RESISTORS (150 Ω)

MANY THANKS TO

• JORDI SALVADÓ (for help and suggestions)
