ATMega162 delay()

[Andrii29102003]

When I use the internal 8 MHz clock, delay(1000) waits for 8 seconds. But when I use the internal 4 MHz clock or others, delay(1000) works correctly and waits for 1 second.

The microcontroller is most likely running at 1 MHz. Select the "8 MHz internal" option, and clock "burn bootloader" before uploading your program. If "No bootloader" is selected, it will only set the fuse settings to run at 8 MHz

I’m using it with the bootloader — maybe there’s something wrong with my ATmega.

Check you CKDIV8 fuse and/or CLKPS bits. The CLKPS bits can be set from your program as well, regardless of what CKDIV8 is set to. CKDIV8 just sets the startup value.
