Build a 3.5mm Audio Switch

audio mux p2

I moved to Berlin a few months ago to start working as Lead Electronics Engineer at UNU Motors. As soon as I found my own place (after spending three months apartment hunting), I decided to buy a good audio monitor, so I could listen to music and watch videos with a decent audio quality. My choice was a BX5 M-Audio audio monitor, great speaker at a very good price. The only annoying thing is that every time I wanted to listen music from my computer, I had to take the P2 plug from the RaspberryPi (running OSMC) and connect to my mac, and vice versa… To fix this problem, I decided to make a small PCB where I can plug everything together and then flip a switch to toggle inputs.

Arduino Crash Course: Get up and running in 1 hour

Have you heard of the Arduino? Its a small but powerful micro-controller that can be used to create many amazing things. An Arduino can be used to sense its own environment, connect and communicate with the Internet, manipulate devices around it, send messages, and much much more. Last year, over 700,000 hobbyists were using and contributing to the Arduino environment.

This course is designed to take you from 0 to 100 with Arduino in less than an hour. At the end of the course, you’ll be fully familiarized with Arduino and ready to build your own applications and devices. Ideally, this course is for beginners who want to get their toes wet with the Arduino system but those already familiar with Arduino can still learn from the techniques used in this course.

What you’ll learn in this course:

– How to setup the Arduino software and start outputting code
– How to understand and write code that your Arduino can understand
– How to setup Serial communication
– How to use a breadboard, and RGB sensor, and a LED Pin.
– How to create a variety of functions that interact with your Arduino
– How to create a device that detects your rooms temperature and changes colors accordingly.

ALL IN LESS THAN ONE HOUR!
