Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).

Here’s a no-PCB Arduino that doesn’t obscure the DIP ... allowing it to be used in a breadboard or DIP socket. You can see a walk through of the components in the clip after the break.

Like the Arduino Leonardo it has a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply ...
