Divím se, že to ta stavebnice neobsahuje rovnou. Ale jak se psalo u diskuse k stavebnici od TIPA, kde byl taky problém kolem krystalu, je to asi cílená léčka na nováčky. 
To use a 32.768kHz watch crystal as the clock source for the device, the Low-frequency Crystal
Oscillator must be selected by setting the CKSEL Fuses to “1001”. The crystal should be connected
as shown in Figure 11 on page 27. By programming the CKOPT Fuse, the user can
enable internal capacitors on XTAL1 and XTAL2, thereby removing the need for external capacitors.
The internal capacitors have a nominal value of 36pF.
Ale stejně bych je tam vždycky dal.
