Make Your Own LED Matrix !

[@PraveenMax]

Finally, someone explains electronics instead of simply putting BG music. Thx!

[@quixsticks]

I saw this project on instructables by system X. I tried to solder the components on a perforated circuit board but I couldn't get the solder to flow the way I wanted it too. Your PCB design helped me to complete this project. I couldn't have done it without your PCB design. Greetings from USA.

[@ChinmayDhumal]

Next up on Nematics Lab - I made a 1920×1080 wall sized display because I had a few LEDs lying around and didn't knew what to do.

[@Nematics_Lab]

Absolute Mad Lad

[@iProgramInCpp]

That would require almost 2 MILLION LEDS! It would be: - inefficient - expensive as hell - take days to solder

[@ChinmayDhumal]

@@iProgramInCpp Sarcasm bud :)

[@ArneChristianRosenfeldt]

@@iProgramInCppbut this is how these walls work. We just need to build a robot to do the job. LEDs from tape.

Really nice work. Thank you for uploading the video. I also plan to build my own LED matrix. I will use this as a reference.

the schematics are not that accurate :D

[@mylesmeyer9689]

I love this video. I am looking to have 36 machines send a signal back to my office telling me what state of operation they are in. Using multi color LED's to tell me the different states. I think this video might get me in the right direction.

[@manofmesopotamia7602]

You made the driver pcb using JLCPCB, but why you did not make the led matrix using JLCPCB too?

[@thomasquinot5273]

Interesting! Can you explain why you used a 4017 for rows rather than a fourth 74HC595?

[@christopherbutler8176]

i was wondering this too.

[@tanbirpradhan]

Beacuse 4017 is a decade counter but 74hc595 is a shift register....❤️❤️❤️

[@TheJosemartel]

Nice. Good job. Now you can add a bluetooth system and, from de phone, you should send the text to your arduino.

Sir, if I want more than 6 row in it then what should I do and which ic I need for it

I solder 8x8 Dot Matrix. I use Anode as Column and Cathode as row. I use 2 of 74HC595. I connect each row directly to 74HC595. Now I'm able to display text but it's flickering. I was told to use 8 of BC547 transistor for each row. Do they fix the flickering problem?

[@ArneChristianRosenfeldt]

Speed up the frame rate. Scroll only every nth frame. Or use higher resolution

what wire did you used to connect all anode sir?

[@EyeMCreative]

I'm still a little confused. How are you able to toggle whether or not a row is grounded, and also how do you not have issues with unwanted LEDs turning on

[@ArneChristianRosenfeldt]

There surely is a power transistor per row. LEDs like any diode block current in one polarity. 3:45

[@joerinaldi5]

As mentioned previously my strength is in electronics not Arduino software. I do not know which lines of code effect the addition of another 24 columns. Can you give some assistance?...thanks

Hey friend can you help me to make digital clock problem is only power supply, 1) First I purchased 2.5 inches(approximate) 7 segment display but it requires 9V for each segment and I was not able to use high side transistor switch, so I made my own segment display with 2 led for each segment and total of 2*7*4=56 LEDs, and they also not glowing as expected, now I'm working on 3rd experiment on bread board with total of 28 LEDs, one LED for each segment. So nearest 7 segment works with maximum brightness and decreases with distance, thanks in advance

[@deepeshpadala5329]

Is there any way to control the brightness of each LED using this technique?

[@Nematics_Lab]

You can add a simple PWM voltage regulator at Vcc

[@ArneChristianRosenfeldt]

You run a high frame rate and dither. I Wonder if it is possible to put a latch after the shift registers. Then per row you can load new versions of this row where more and more LEDs go dark. Then clock the latch ( without the latch would worry about EMI ). Shift registers are fast. You can probably do 8bit at this low resolution.
