does mood cue need capacitors to work
If you're in a sceptical mood, maybe not. Maybe there's a huge government conspiracy to convince the public that capacitors are vital to national security.
For the benefit of the forum helpers who don't have an Arduino Project Book, the purpose of the capacitors is explained as:
When a servo motor starts to move, it draws more current than
if it were already in motion. This will cause a dip in the voltage
on your board. By placing a 100uf capacitor across power and
ground right next to the male headers as shown in Fig. 1, you can
smooth out any voltage changes that may occur. You can also
place a capacitor across the power and ground going into your
potentiometer. These are called decoupling capacitors because
they reduce, or decouple, changes caused by the components
from the rest of the circuit
You can see the breadboarded circuit for the project here:
Well, usually shocking myself with really big capacitors changes my mood
The manual shows two capacitors so i would say yes, if you're encountering any additional problem you can write some more information or post your code.
It might work without the capacitors but don't count on it. As a general rule if something doesn't work fix the obvious problems first, in this case if it doesn't work without capacitors then add the capacitors before looking for anything else. In case you don't have the exact capacitors specified don't worry, in many cases the exact values of of electronic components is unimportant. In this case as long as the voltage rating is above the voltage of the circuit then choose a capacitor of the specified value or higher.
