The Idiotware Shield is a learning platform for quickly bringing to life hundreds of Arduino projects, whether you’re a novice or expert. The Idiotware Shield is the Swiss Army Knife of Arduino shields, with plenty of integrated inputs and outputs and options for connectivity and expansion.

31 Days of Simplifying Arduino

For every day of this crowdfunding campaign, we’re going to publish a new project showing how the Idiotware Shield simplifies creating awesome Arduino projects. Here we go!

If there are specific demos you’d like to see, please let us know!

Student Tested

The Idiotware Shield is for anyone who wants to quickly bring their IoT ideas to life with minimum hassle and expense.

To make sure we got it right, we spent over a year testing the Idiotware Shield with more than 300 students, most of them in middle school and some as young as nine years old. With the Idiotware Shield, the students quickly got to the core of their ideas, without being distracted by wiring, bulky stacks of multiple shields, or piles of datasheets. See below for more information on our development process.

Features & Specifications

Completely Open Source and Compatible with Everything

We believe in open source and have made everything about the Idiotware Shield open source:

Because everything is open source, you can use the Idiotware Shield with a huge number of other tools, such as:

What You Get

Idiotware Shield

The shield itself is ready to use with any supported Arduino board.

Add-on Modules

The Idiotware Shield has four expansion ports dedicated to specific modules you can buy as add-ons:

For backers who wish to program the bundled ESP8266-01 module, software and programming support is available for Windows, Linux and MacOS.

Arduino Uno and Accessories

You can use the Idiotware Shield with your own Arduino board, or you can get an Arduino as part of this campaign. Any pledge level (see the list to the right) that includes an Arduino comes with:

For Beginners

With the Idiotware Shield, you can make its on-board LEDs shine, blink, change colors, and dance to the beat of the on-board multi-tone buzzer.

Basic Project Example

For Intermediate Learners

Integrated on-board the Idiotware Shield are environmental sensors, like temperature and ambient light, and human interfaces, like switches and a touch sensor.

Intermediate Project Example

The Smart IoT Postbox is an example of an Intermediate Project

For Advanced Learners

You can query and process the Shield’s sensor data and control the Shield’s outputs over Wi-Fi using a cloud server or over Bluetooth using a phone. The Shield can log data (offline) to an SD card (up to 8 GB), using the integrated microSD card socket, to be retrieved manually or as soon as Wi-Fi or Bluetooth connectivity becomes available.

Advanced Project Example

Create an ON AIR station with the help of the Idiotware Shield.

Development Process

Our journey building the Idiotware Shield started when we built a very basic prototyping shield, which was named the Curiosity Gym shield v0.1.

An early prototype of the Idiotware Shield

Some of the projects the students prototyped with the v0.1 of the shield include a chess clock and a security system that sounds an alarm when someone passes through a laser beam, a.k.a. the laser maze.

Some of our beta testers and their laser maze

After the quick prototyping phase, students used coding techniques to reduce the size of their project as a second iteration. We very quickly realized that we had to bring in communication interfaces (Wi-Fi, mesh radio, and Bluetooth), along with a low power display to the Shield.
