(Sorry I have edited the title previously said common cathode)I began some small projects when the lockdown started as I have always wanted to set aside time to do ths things, but never seemed to have the time to do it.
Anyway I began a few arduino projects with LEDS and I have begun building and RGB LED matrix with Common Anode 5mm 3.3 volt leds.
I have previously produced a Common Cathode matrix of 8x8 RGB Leds but could not find a common cathode project tutorial so I began a common anode.
My original plan was to build a 8x8x8 cube, however the programming and set up is a little ambitious for the level of experience I have but understand the processes behind the programming a bit more on 16x32 matrix.
The probem I have is that I would like to build the 16x32 matrix and I have parts to either build with HC74595 or LM3914 display driver (though I believe those are for monochromatic), IRF 9450 P Channel Mofsets, and \TLC5940 chips to go with them, and this the problem, which way to go? I am trying to find a schematic using one of those chips to build on and create a 16x32 matrix, I have been taking images at each stage (even keeping the screw ups) to show at a later date and could do with some advice as which chipset to use and if anyone could point me to a reasonable schematic to follow, I understand the principle of daisy chaining the chips together, its just I have not seen a schematic for a row longer than 8 bits. I have Uno, Micro and ano Arduino and a few compatibles and plenty of everything else including standard components. I am also looking to add the ESP8266 (Arduino wifi module) into the schematic in order to upload new 'images' I also believe that the RGB leds are 8bit.
Im not looking for other people to do my homework I am hoping for a couple of pointers on where I can read up on what to do next or a tutorial that will help me decide which way is better to go (or at least how to chain 16 leds together, I understand the principle that 'pushes' the values of the leds using the shift registers and persistence of vision, but I cannot find a rgb matrix larger than 8x8 unless its for a pre-manufactured device.
In tthe matrix the columns1 are the common anodes connected and each row are the cathodes of each colour if that makes sense. I intend to upload a schematic later after posting.
Can anyone tell me where I can follow a similar tutorial to build this size?
I will post the entire project when complete.
Many Thanks in advance.
