I just started playing with Arduino not long ago.
I began with a starter kit from SparkFun. The kit didn't come with any transistors, and I'll need some.
Where do you folks usually buy parts? (both electrical and non-electrical, like transistors and wheels, respectively)
Should I buy online? Any recommended sites?
...or should I just go to RadioShack? (I'm worried about prices)
...... or should I just start tearing apart my old rc cars?....
