goods

material ：

3D Model ：Cults3D

LED (WS2812 60led/m):

Magnet diameter ：12.7 Mm height ：5 mm x2

Little magnet ：（ Neodymium magnet 5mm x 3mm）

Magnetic switch （ Or reed switch ）：https /wiki.seeedstudio.com/Grove-Magnetic_Switch/

Arduino Nano One

5v The plug

5V Do not plug

Silicon wire

The first 1 Step ：3D Print all parts

For this lamp , You need to print 7/8 Parts . You can find these parts here .

General print settings ：

• fill 20-100%
• No support

LED Lamp holder setting ：

• fill 100%

Why 100%？ Because you want to diffuse the light well ！

The first 2 Step ： Make LED Diffused lamp holder

You will need 3 Wires from LED Connect to the base of the lamp . This is the hardest part of the whole build .

Get ready / material ：

• Cut it off 3 The root length is 130 Mm wire （ You have some room for trial and error ）
• Cut a piece suitable for the diffuser LED Lamp with .
• Get your soldering iron
• Get the diffuser , Diffusion top and LED clip .

Pace ：

1. First, connect all wires ** Weld to LED On the light bar .** I use only white lines for the look of ecstasy . Make sure to mark the wire at the end , So when you connect them to Arduino when , You won't be confused .
2. Pull the wire all the way Through a small hole in the diffuser .
3. stay LED Stick some glue on the inside of the light bar , And then Its （ Use tweezers ） Put it inside the diffuser . If your LED Don't want to stay on a small piece inside the diffuser , Please put LED The clamp is connected to LED middle .
4. weaving Wires for a beautiful look .
5. Place the magnet on top of the diffuser .

The first 3 Step ： Prepare the power input

You can also choose to use the battery 、 Move the power supply or something else to do this . This is what I found best for me .

Get ready / material ：

• hot glue / seccotine
• Female power socket connector
• Lamp bottom surface
• Red and black cables

Pace ：

1. Stick the power socket connector to the opening on the bottom of the lamp .
2. We need to be in Arduino Cables used in the welding procedure .

The first 4 Step ： Making magnetic switches

This is optional . This is the function that turns off when you connect it to the lamp holder . You can also choose to just unplug it , Just put a magnet on the base . Depending on the availability of the part ;）

Get ready / material ：

• Magnetic switch
• Little magnet
• 3 Line
• Magnets / Switch base
• Soldering iron
• clamp

Pace ：

1. Remove the white part from the magnetic switch with pliers .
2. stay SIG、VCC and GND Upper welding 3 A wire .
3. In the magnet / The round side of the switch base is glued with a strong adhesive , Then slide the switch into place . Please note that , We need to test whether the switch is not triggered by a small magnet . Because if it is triggered , The system will not work ！ We will be in Programming steps Test this in .
4. Put the magnet / Place the switch base at the desired position on the bottom surface of the lamp , When placed on the lamp holder , You want to turn off the light . By putting what you have already made LED Put the piece and the magnet in Lampholder Test on the other side of the .

The first 5 Step ： stay Arduino Upper welding

Get ready / material ：

• Soldering iron （ And accessories ）
• Part of the previous steps
• Aduno

Pace ：

1. take 2 A cable is connected from the power jack to VIN and GND.
2. take Ledstrip Wire welded to GND、V5 And digital ports (D1-D12).
3. Weld the magnetic switch wire to GND、V5 And digital ports .

The first 6 Step ： Yes Arduino Programming

This is an easy step . Do you use the same components as me ？

Get ready / material ：

• Computer
• Aduno
• miniature USB Line

Pace ：

1. download arduino IDE
2. install FastLed library （ It depends on what you use LED）（Fastled）
3. Magnetic switch Code Overview
4. take Fastled Code combined with magnetic switch code
5. See if your magnetic switch is triggered . Adjust him accordingly by sliding backwards or forwards .
