The search volume for "arduino" keyword alone is puzzling.
It is much more looked for than "atmega" and sensible more searched than "multimeter" or "transistor".
arduino - 94
atmega - 2
attiny - 1
multimeter - 27
transistor - 33
It is self evident that the ones that look for "arduino" are not interested at all in atmel AVR microcontrollers.
Strange!
