On an Arduino that is correct, but I was wondering if it is actually accurate on an attiny.I have programmed some attinys at 8MHz even and found the delay() can take 5-8 times longer than specified.If you find the times correct then obviously i am doing something wrong. However, do we really know how long our showers actually are? The Attiny has an 8 MHz timer that is by default divided by 8.So if one programs it for 1MHz, that is OK.As I programmed it for 8 MHz, the program thought it was 8 MHz, but the chip still thought it had to divide the clockspeed by 8, hence the delays being some 8 times slower..What I did was to first burn the bootloader. I would imagine a reset time of at least 5 minutes would fix those types of shenannigans.
