Story

DIY Christmas Tree

Hey Friends....
Merry Christmas in advance.
I know it is too early to wish Merry Christmas.
But I make an Arduino project In which you can make A DIY Christmas Tree with the help of LEDs.
You can watch the video for detailed Project or Follow the steps to make it.
Things you need
1.LaminatedthickCopperWire(19cmlong30wires)
2.ArduinoNano
3.15differentcolorsLEDs
4.PushButton
5.100Kresistor
6.Jumperwires
7.CardboardPlatformtoputtree
8.HeatShrinkTubes
StepstomakethisProject:-
1. Take 2 pieces of laminated copper wire, scratch it from above and solder led both legs to separate copper wire.
2. Solder all the 15 LEDs on copper wires tip.
3. Put heat shrink tube to cover the soldered part of led
4. Mark + and - on copper wires.
5. Twist all the copper wires to make a Tree.
6. Solder copper wires at the end and put heat shrink at the end.
7. Stick tree which you made on the cardboard platform
8. Do decorations
9. Do connections from circuit diagram
10. Upload code
Your DIY LED Christmas Tree is done...
