MagiQuest Wand "hello world"

Parts List

Hardware:

• Arduino Uno
• IR Receiver (I used an OSEPP IR Receiver Module, AdaFruit IR Receiver Sensor should also work)
• MagiQuest Wand

Software - Arduino IR Support:

1. Arduino -> Sketch -> IRRemote

Or if IR support isn't alrady installed:

1. or Arduino -> Sketch -> Include Library -> Manage Libraries...
2. search IRRemote
3. Install

Wiring it up

Basic Project - Servo and MagiQuest

The magi-spin project is a basic example of using a MagiQuest wand to control a servo. In repsonse to a wand wave, a servo will quickly swing back and forth.

• Arduino Uno
• IR Receiver (I used an OSEPP IR Receiver Module, AdaFruit IR Receiver Sensor should also work)
• Servo (I used an Adafruit Micro Servo)
• MagiQuest wand

Decoding MagiQuest

A breakdown of the signal characteristics of a MagiQuest Wand is available over at OpenSchemes. Instead of hand decoding the entire IR signal, we piggyback on the IRremote Arduino library, with a few modifications courtesy of mpflaga's MagiQuest fork of IRremote.

We lifted the MagiQuest specific code from mpflaga and, with a few changes, directly included the relevant decode functions in the Arduino Sketch. The function of interest is decodeMagicQuest, which is called with a pointer to an IRremote::decode_results structure, and the magiquest structure we declare at the top of the sketch. Calling the decodeMagiQuest will decode and fill in the data in both the decode_results and magiquest structures:

decodeMagiQuest(&results, &data);

// the wand id is also in results.value
Serial.print("wand_id: ");
Serial.println(data.cmd.wand_id);

Serial.print("magnitude: ");
Serial.println(data.cmd.magnitude);

IR Sensors

I've used the following sensors successfully (with no code changes):

• OSEPP IR Receiver Module
• SunFounder Infrared Receiver Module
• Adafruit IR Receiver Sensor
