Getting two extra pairs of VCC/GND on Arduino Uno (and others) – SyedTips – 4

We often come across projects where we’d like to quickly hook up a sensor or an actuator that works on 5V to an Arduino (Uno and others) without using a breadboard. Since the Uno has only one 5V Pin, an easy way to get additional pairs of VCC+GND is to use the ICSP headers available for the Atmega328 and Atmega16U2.
