Make your own 15x10 RGB LED Matrix - Part 2
video description
Search for rgb led addressable string. They are currently (depending on the exact specs, waterproof, LED separation distance, 3V / 5V, LED bulb size, etc) about 10 / 50 LEDs. Cheaper, easier and much nicer than soldering up your own, no need for wire, no need for capacitors, etc.

Loved the video! Could you please provide an schematic of the wiring? I don't know what to do with the data out of the last LED. Two more questions: the 150Ohm resistor goes between data in of the first LED and pin3 of the Arduino? How exactly did you connect 5V and GND to two LEDs of the matrix which are positioned far away from each other?

Great video, I've have a bag of those LED's and plans to connect some of them up to a ESP8266. A current limiting fuse per columns might be a good idea considering your structure is made of cardboard and you're running a 12 amp power supply with high current capable wire?

The data corruption you are experiencing is because you did not decouple each LED, NOT the poor power wiring (although that is important too.
You did if afterwards, sure with the capacitors - But you didn't think it was the problem that it was originally.

where can I learn how to wire circuit board's and what circuits does what. Ive been wanting to learn because i find a huge intrest in this. and also if I were to take a collage class for this what would it be under. Thank's and keep up the awesome work.

Wouldnt it have been easier to use the SMD strip LEDs glued to a backer board and then jumpered to each other keeping everything stuck to the backer board! Then they could have all been in the center of each box.

How did you manage to fix the signal distortion problem? Having a problem where it will be all blue one minute then it will turn all different colors the next minute after a power cycle.

Can you make a 32 x 32 one? (I know it probably requires quite a bit of power and will be time consuming, but you might be able to make a game on it? Very low resolution though)

0: 45 You made a small mistake, DIP stands for dual in-line package, it is the standard package used by ICs with two rows of pins but not most LEDs, and not any of the ones you showed.

2: 01 It's not Chinese, but rather it's Japanese. The reason it looks very similar is because Chinese and Japanese share the same characters, except for Hiragana and Katakana.
