The problem is, no matter what I try, single Uno is not enough for my configuration. LCD, 7 segment module on TM1638 and 7segment module on 73HC595 take up 12 lines of IO, and I need at least 7 or more of analog inputs, so I have two options, buying Mega, which will be possible in a month or so, or using two arduinos. I hope to figure out the "dual arduino" thing before I get to buy Mega because I dont like to abandon an idea before I do everything I can, so I'm open for suggestions.

Thanks for the replies, I might try that when I'll have money, but I'm trying to work it out with what I've got. Do you think that hardware I2C would work faster than software serial?

Hi everyone, it's my first post here. I'm making a control panel made of 2 arduinos, lcd, 2 sets of 8x7 segment displays, switches and propably 2 joysticks. The reason I need 2 arduinos is that the displays alone take up all pins on one arduino. Zitronen already suggested me to buy Mega, but right now I don't have funds for it and it will be a good prooving ground for me . I figured out the comunication between arduinos with SoftSerial and EasyTransfer, but it seems somewhat laggy. I forward every packet of VData to the second arduino but it looks like it's loosing sometimes even half a second of data. Does anyone know a way to help me? Maybe EasyTransferI2C will work faster? Any help will be appretiated. And Zitronen, thanks again for fast replies and an awesome plugin, you're the boss
