Introduction: How to Make a Spinning LED Light in Minutes – No Programming

Recently a gadget called fidget spinner has like swept the globe. It's said to help office workers reduce pressure and children concentrate. They are the latest hot fad on the market. But its fun is more than that. Some creative makers have added some LEDs to each corner and amazingly made it a flashing spinner! The flashing effect is quite easy to DIY. Follow me to make a gorgeous spinning LED in just a few steps with simple components.

Step 1: Materials Needed

DC motor (with propeller) - http://bit.ly/2sMbO06

Red LED + orange LED (any color you like)

Some wires (male to male)

Slide Switch

9V battery

Battery Buckle

2 x button cells

Electrical Tape

Glue gun - http://bit.ly/2twpx8w

Soldering pen - http://bit.ly/2t3fPKx

Step 2: Preparation for Motor

Let’s start from the motor. Here I use a male to male wire to extend one end of the motor. Solder the wire to the one end.

You can mount the propeller in this step or in later step.

Step 3: Power and Fix the LEDs

Before starting the following step, we should figure out the two poles of the LED. It’s quite simple: the longer one is the anode, while the other is the cathode.

Connect a LED to a button cell, anode to anode, cathode to cathode, and fix them with the electrical tape. Wrap them tightly in case of a loose connection. Then glue the other LED to the other cell in the same way. Now the LEDs should light up directly. If not, press the tape and wrap the cells more tightly.

Step 4: Fasten the LEDs to the Propeller

Glue the two LEDs to each blade end. Then mount the propeller on the motor’s top.

If you don’t have a propeller, try a cardboard. But you need to use the glue gun to fasten it. It works too.

Step 5: Preparation for Battery

Press to fasten the buckle to the battery’s top. Then glue the slide switch to the battery.

Solder one wire of the buckle to the middle pin of slide switch.

Step 6: Connect the Motor to the Battery! Done!!

Remember to slide the switch to OFF position. This switch is used to connect or break the circuit, providing convenience to control.

Solder one wire of the motor to the ON pin of the slide switch, and the other wire of buckle to the other pole of the motor.

At last, fasten the motor to the battery by glue.

Now, it’s all done, enjoy the spinning LED light in a dark environment. You can add more LEDs of other colors on the propellers to try. Set them at different distances to the motor shaft, so you can get more circles of flashing on the blade travel.

Step 7: Extension of Adding a Vibration Switch

Remove one LED from the propeller to add a vibration switch (or directly add to the blade).

First, connect one pin of the vibration switch to the button cell’s cathode, and connect the LED’s anode to anode of the cell.

Then wrap the cell with the electrical tape to avoid the other pins of the switch and the LED touching the button cell.

Next, connect the other pins of the switch and the LED button cell, and fasten by soldering. Then glue this whole button cell to the prop.

Here you need to mind, place the head of the vibration switch facing the center of the propeller. Thus the LED circuit will be on by the small ball in the vibration switch under centrifugal force. Otherwise, the LED will not shine during the spinning.

Why dont you take supply for LED from 9V battery. This will remove the extra weight on propeller will lit the LED when the motor is on. Some how supply the power to LED through rotating prop.

If we take supply from 9V battery, the 9V voltage will burn the LEDs. Besides, the rotating prop will twist the wires to the LED.
