A previous post (here) documented how to connect a Python script to a serial port on a microcontroller. This post documents connecting a serial port to the WEB via Node.js (which is a JavaScript runtime). Using Node.js and a module for node called serialport, it is very easy to connect a PC to a serial …

Are you ready for another off topic article on WebRTC? This one is titled WebRTC Phone Calls via Asterisk. I have written about Asterisk before (HERE) and that article did have something to do with microcontrollers 😎 Asterisk is an open source full featured phone system (PBX). In my last post about WebRTC, I showed …

Are these ‘gadgets‘ just toys or do they have a practical use? Most people who ask though, are not that familiar with arduinos or microcontrollers in general. …

Previously, I wrote about RS485 communications between two Arduinos using a MAX485 IC. The link for that post is HERE. It showed one Arduino as a tranmitter and the other as a receiver. This post is very similar, however, I am using a different IC, the SN75176BP. This post is about SN75176 RS485 communications between …
