Ensure that you can log on to the remote host without a password, e.g. by using SSH keys.

1. On the remote host, create a FIFO

Introduction

This is a dead-simple way to test that GPIO on the Raspberry Pi is working. I have an SKPang Raspberry Pi starter kit A. But all you need is

• An LED.
• A button.
• A resistor, approximately 270Ω.
• Some way to connect these to each other and the GPIO pins.
