35 Week Arduino Class Series Scheduled For 2017

We will be starting a comprehensive 35 week arduino class series designed for anyone interested in learning electronic design and microcontroller programming. No experience is required, and all you need is an Arduino and several low-cost components. The workshops will start on Jan 4th, 2017 and run weekly through Aug 30th, 2017. more ...

Virtual Color Mixer

This example demonstrates how to send multiple values from the Arduino board to the computer. The readings from three potentiometers are used to set the red, green, and blue components of the background color of a Processing sketch.

Hardware Required

  • Arduino or Genuino Board
  • 3 Analog Sensors ...

Visualizing Music With FFT

The following videos are displaying patterns generated by a Processing program doing real-time FFT (Fast Fourier transform). Basically it is visualizing music in the frequency domain using a polar-coordinate particle system.

The hardware makes use of Adafruit 8x8 neopixles, two 5v 10amp supplies, a FadeCandy controller, 16 AWG stranded wire ...

Understanding Data Types for variables

A data type in a programming language is a set of data with values having predefined characteristics. Examples of data types are: integer, floating point unit number, character, string, and pointer. Usually, a limited number of such data types come built into a language. The language usually specifies the range ...

NeoPixel 16 Ring Fun

alt text

NeoPixels are fun and amazing. In my project I connected 4 of the AdaFruit NeoPixel - 16 RGBW Leds together. What caught my attention and curiosity was that you can control each of these RGBW Leds using just one wire.This feat is accomplished with a very timing-specific protocol. Since the ...
