On Paper: Adding a Decoupling Capacitor to the Power Pins of the AVR

The power pins of the AVR may experience interference from time to time. It is advised to add a decoupling capacitor across the VCC and GND pins of the AVR microcontroller. If the capacitor is located far from these two pins, a high current loop could be formed. The recommended capacitor value is 100nf or .1uf.
