Since The LEDs Are In A Matrix If You Need To Light Up The Led In The First Row And The Led In The 3rd Column The Apply Charge To Negative Charge To Anode Row Of The First Row And The Cathode Pin In The 3rd Column. Now We Have Completed Around 25% Of Our Led Matrix Its Always A Good Thing To Test Everything After Soldering Now You Have Apply Negative Charge To Led Anode Row And Positive Charge To Led Chathode To Light Up The Led. Then Cut The Excesses Lead And Solder Them At The Points.
Ĭut The Excesses Leads After Shorting The Pins For Soldering Now We Have The Cathode Facing Up Use A 3mm Steel Rod Or A Pencil To Bend The Leads With Out Touching The Anode Pins Of The Led.
Once It's Done Bend The Leads Of The Led To Short All The Anodes All Together Or You Can Use A Silver Copper Wire For This Job. A Parallel line Make Sure To Place The Anode At The Top Side Of The Dot Board. Place The Led The Dot Board So That The Cathode And Anode Form. If You Have Much More Time Then You Can Diffuse The LEDs By Using A 1500 Grid Sandpaper So That It Would Be More Attractive. Or You Can Use CR2302 Button Cell For This Job It Will Provide Enough Power To Light The Led For Testing Make Sure You Have Tested All The LEDs Before Soldering To Avoid Malfunctioning Of The LEDs.

Iam Using Green Colour LEDs With Me Sort Of, To Test The Led Use A 220ohm Resistor Series With The Positive Terminal & The Voltage Potential, If You Are Using A Higher Voltage Than 3 volts. Its Simple 😀 Once You Have Done That Step Make Sure To Have 144 LEDs With You, You Can Select The Colour According To Your Imagination, Great Mind. Use A Pointed Pen Knife Or Similar Thing To Make The Cut, Then Bend The Board To Break At The Cut.
Score And Snap The Dotted Pcb In Which Size You Need To Make Your Led Matrix.
