[Rajendra] got tired of building the same basic circuits ... breadboard space when compared to the DIL package of the chip. But consider that the oscillator and its capacitors, reset button ...

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).

Having a 32-bit processor with lots of memory running at 40 or 50 MIPS is a game changer compared to, say, a traditional Arduino ... into a breadboard, but looking back the simple circuit would ...
