yay! a little-ish chip for little-ish projects. but not so little you run out of pins and yell obscenities at it.

i clocked mine to 8mhz on the internal oscillator. but you could run it up to 20mhz with an external crystal (at least thats what i read in the datasheet).
nice little chip. im still not sure what to use it for. probably could use it as some kind of servo channel mixer, or anywhere where i need to convert one type of a signal into another. shortage of pins kinda limits the possibilities.
i really wish sf would stock the tiny84 though, which has twice the usable pins, yet still being small enough for those tiny projects. sometimes i use a mega328 and consider it a waste of functionality and the 2313 has too little flash. but the tiny84 would be a perfect addition to the inventory. especially since i have had a hard time finding a supplier which would ship to ak at a sane rate.

that explains why my opamp hack works. i was using an opamp with gain set somewhere between 3.5 and 5, but only supplying it with 5 volts thus allowing it to clip. everything i knew about opamps said this shouldn’t work, but it did. the opamp must have been boosting the current allowing my arduino to receive a bit stream (and im using the usart and not software serial).
