LED-Blink

In this post, you will be introduced to the basics of programming hardware using the Viam SDK by making an LED blink. This will allow you to write Python or Golang code to make an LED connected to the GPIO of a Raspberry Pi blink. This tutorial is a good introduction to Python programming, and developing code for hardware like robots and IoT devices.

Circuit Diagram

For reference, the circuit you are building for this tutorial looks like this:

Prerequisites

You will need the following hardware, tools, and software to complete this project:

Hardware

• Raspberry Pi 3 or 4

• Solderless breadboard

• Jumper wires for easy hookup

• Resistor pack

  • You will be using a 100 Ohms resistor, which is the resistor colored with brown-black-brown

• LED

Software

• Python3 or Golang

• Viam Server

• Viam Python SDK or Viam Golang SDK

Installation

1. Install Viam Server on your Raspberry Pi.

2. Clone this repo onto your development machine:

git clone [email protected]:viam-labs/LED-Blink.git
