I am on a project to build a 8x8x8 LED cube having common cathodes in each layer. I have built the cube and now I have to build the main circuit. I am using my Arduino Mega 2560 to control it.
I have a big problem in selecting transistors for the layer of the cube. I saw a video in which she used two 2N2222 in parallel to get the desired output. Can anybody help me how is that done.
How can I connect two 2N2222 in parallel to get double the current rating? Or can anybody suggest another MOSFET which can be used in my project.
Please provide the pin diagram so that I can understand clearly because I am working for the first time with transistors and MOSFETs.
Actually I have 64 anodes and 8 cathodes . I am driving 64 anodes using shift registers and i needed the help on 8 cathodes section.
