I thougt uploading via ISP-programmer deletes the bootloader?

but you can run on a lower Vmin value....
The other thread doesnt help - there was no solution for the serial-problem at 1mhz...

Hi,

this is **very **interesenting for me. could you write a small tutorial when you solved it? i failed until today to use arduino ide with 328p@4mhz(or lower) with arduino bootloader. i read something about compiling a new bootloader - but this is too much for me to go and i didnt find a compiled bootloader for 1 or 4mhz to download

greetings

Maybe its better to open a new thread for this question?

read the description:

"but it's always best to avoid long-term (over 1 hour at a time) submersion, if you need something that can be submerged for over an hour you may want to find a different sensor. "

check the voice-recognition in Openhab for example. it is cheaper and a better solution then realizing this in hardware...

ok, great Lets how they look ready....

Eagle is much easier than it looks. I started a few ago with my first pcb. After looking one or two tutorials, i got my first successful schema. Just give it a try. One evening and a beer or glass of wine is enough to learn eagle.

Update: PCBs are shipped via express...
