Arduino uno R1 and Arduino uno R3 Questions

Hey guys,

I'm new to arduino and just bought an uno r1, I'm wondering about the differences between the uno r1 and uno r3. Can I run uno r3 sketches on uno r1? And is there any big differences? This will really help. Thanks! XD


All differences are explained here, grasshopper:

Biggest change is the extra diode from reset pin to +5V, supposed to keep reset from causing lockups.
