Circuits.io isn’t new – it’s been around since 2012 – but these entry-level Arduino tools help improve the product and make it easier for newbs to get into hardware hacking without zapping ...

123D Circuits is created by Circuits.io and Autodesk. It allows you to create a virtual environment using breadboards, Arduinos, and plenty more.

Arduino fanatics rejoice: Autodesk and Circuits.io have jointly released a new electronics design tool with some unique features: 123D Circuits.

Autodesk released 123D Circuits in September 2013, which expanded on the existing Circuits.io app by adding a breadboard view, and let users run code and simulate circuits in the app.
