Introduction: Names and Design Led Fidget Spinner
A fidget spinner made from single microcontroller atmega 8 and 8 leds
full youtube link is here..
Step 1: Important File Need to Develop This Project
pcb file open in diptrace
stl file for 3d print
Step 2: Parts Require for Making This Programmable Led Fidget Spinner
To make this one you require:
1 smd leds(8 pc)
2 atmega smd(1 pc)
3 330 ohm smd resistor(8 pc)
4 fecl3 solution(1 box)
5 copper clad
6 bearing(1 pc)
7 button cell(3 nos)
8 usbasp programmer
9 soldering iron
Step 3: Making the Pcb First
you can download the pcb file and print it by using a laser printer and then transfer the toner on pcb clad.
now mix the solution in cold water and put the circuits and let the etching process be done.
after etching remove the black carbon layer by using thiner or petrol
Step 4: Soldering the Electronics Components
now first put the liquid flux on the layer of pcb and put the atmega 8 and solder with pointed soldering iron
next pcb put all the led negative one side and positive one side and solder them.
then put the resistor and solder them too...
Step 5: Connecting All Wires
now take a thin insulated motor winding wire and connect them as shown in image with diagram
prog pin written should be connected to female header pin for usbasp programming
Step 6: 3D Print the Model and Set the Bearing to It
print the model by using 3d printer
clean a bearing of 26mm diameter by petrol
Step 7: Programming and Dumping the Code
download winavr software and usbasp device driver and install it.

LIKE FOR A LETTER S WE NEED TO JUST SEE THE EXCEL SHEET AND PUT 0 AND 1 ACCORDINGLY In this way we write the names and to program it use fischel programmer
now first click on make all in tools
then make program to dump the code.
We have a be nice policy.
Please be positive and constructive.
