Using an arduino for a timer is a spectacular waste of resources and very bad engineering (unless you already need the arduino), you might as well use a Core i7 to blink a led. The pricing will be about the same, you pay for the plastic package and shipping. Silicon price is very low.
- jrockway 14y agoIsn't having two factories, one to produce a 555 and the other to produce an ATtiny, the waste of resources? I personally prefer to only have to keep one chip in stock; the factory-calibrated RC oscillator is more accurate than what I would build out of discrete components anyway. (Also, an ATtiny is not an Arduino. The Arduino chips cost like $5, an ATtiny is 50 cents. ATtinys have much less flash, EEPROM, and ROM. But can still produce a nice square wave :)
