Hello,
I have a Arduino Pro Mini and I want to change it that it uses the internal clock @ 1Mhz.
In the past I did this by changing the fuses with AVR Studio and afterwards I needed to create a board in the Arduino IDE for 1Mhz.
Now I want to do this again, but I see that the Arduino IDE is changed regarding this for adding boards manually.
How can I use the Arduino IDE with a Arduino Pro mini that uses the internal clock @ 1Mhz?
