This article covers setting up the Raspberry Pi 3 Model B+ for headless SSH access over WiFi using a Mac or Windows.

This article covers setting up a Pi Zero for SSH USB access using a Mac.  A link to the Windows instructions can be found in the article.

When I received my Raspberry Pi NoIR Camera I wanted to try it out on a headless Pi 3. The problem is that the camera doesn’t display anything when you connect over VNC or Remote Desktop. Sure I could have hooked up a monitor, keyboard and mouse. But how is that going to help me when I want to build something like a wireless crittercam?

The easiest way to setup a Jetson Nano for headless WiFi is to use a USB adapter. The EdiMax EW-7811Un is popular for use with the Raspberry Pi. It can also be used with a Nano, but requires a command line setting to get it to act reliably. I will show you how to do that below.

Recently I wrote an article titled How to Control an Arduino Uno with NodeJS (scriptable.com). In it I discussed how to control an LED over HTTP using an Arduino hooked up to a host using NodeJS and the johnny-five library. In this article I’m going to expand on that to show how to use a similar technique to control a couple of micro servos.

In this tutorial I’m going to show you how to drive an Arduino Uno using NodeJS. The Arduino Uno is a popular microcontroller board for hobbyists. You can control things wired to it like LEDs and motors. To program it you write code in an IDE and then upload the code to the board. The upload happens over a USB cable.
