GPIO Demo (LED)	M	An LED A Breadboard Two Male-Female jumper wires 470 Ω color ring resistor	LED stands for Light Emitting Diode, and glows when electricity passes through it. The longer leg (known as the 'anode'), is always connected to the positive supply of the circuit. The shorter leg (known as the 'cathode') is connected to the negative side of the power supply, known as 'ground'. Breadboard: See Breadboard Introduction. Resistor: Resistors are a way of limiting the amount of electricity going through a circuit; specifically, they limit the amount of 'current' that is allowed to flow.

Breadboard Introduction

The breadboard is a way of connecting electronic components to each other without having to solder them together. They are often used to test a circuit design before creating a Printed Circuit Board (PCB). As shown in the following figure, there are two lines at the top and the bottom respectively of the breadboard. These two lines are used for power connection: the blue line is for negative and the red line is for positive. Besides, they are divided into two sections, and the holes in each section are connected.

In each column (from A to E, and F to J), holes are connected electrically. In each row (from 1 to 57), holes are not connected.
