Our first project is going to be to attach an LED and resistor to the GPIO pins and switch the LED on and off.
We will look at how we can do this using both C and Python. Let's get started setting up the hardware.
In order to build this project you will need the following components:
LED
270 Ohm Resistor
Breadboard
Wires
We will setup the circuit as follows; you can refer back to this diagram as needed:
Start by powering down your Raspberry Pi. Next, you will need to attach the wires from the GPIO pins to the breadboard. You will need one from a ground pin and one from a regular GPIO pin, such as number 4.
Next, we need to add the LED and resistor to the breadboard. The resistor is used to prevent the LED from burning out.
These should be configured as per the diagram, so that the GPIO pin wire attaches to the resistor, the resistor is connected to the LED, and finally the LED is connected to the ground pin wire.
Once we have this setup, we are ready...
