1. RiDuino Projects: Playing the National Anthem Using Piezo Speaker

    Piezo speakers are quite fun components. They can play as well as detect frequencies. The basic idea behind making them play tunes is to send a "Square wave" of the corresponding frequency. By Square wave, I mean , the HIGH and LOW time should be equal.

    How do we get the high and low time out of note frequencies?
    High time = Low Time = 1/(2*NoteFrequency)

    For Example, a basic C note (western musical notation) is 261 Hz. (http://www.phy.mtu.edu/~suits/notefreqs.html) ...
  2. RiDuino Installing Drivers for Windows , Linux or Mac

    Riduino emulates a serial port on USB using Atmega8 to help connect the Arduino loaded controller to your PC. This is done through a CDC Driver.

  3. Riduino - Low Cost Fully compatible Arduino for India

    Riduino is a Arduino based Kit. If you dont know what Arduino is , here is a brief intro -

    Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
    Our aim here at Robotics India was to introduce a Indian Variant which was affordable yet compliant with the official platform. Our main target ...
