Building an Arduino on a breadboard - troubles I faced.

• DxCore

  8 168 8.9 C

  Arduino core for AVR DA, DB, DD, EA and future DU-series parts - Microchip's latest and greatest AVRs. Library maintainers: Porting help and adviccee is available.

I'm a great fan of the newer AVR-DA and -DB chips as they offer much more value for money. They run at 24MHz without a crystal, have 16K SRAM and 128KB flash, more peripherals (e.g. two UARTs) and can be programmed with just a USB/serial adapter (no hardware programmer required). Available in the same 28-pin DIP package for about the same price. There's an excellent Arduino core available with full instructions: https://github.com/SpenceKonde/DxCore

• Ethernet

  60 242 5.1 C++

  Ethernet Library for Arduino (by arduino-libraries)

  

If you use the chip's analog inputs, you should also put a 100nF cap between AREF and ground. You can look at the schematic for any Arduino board on its product page on arduino.cc
