Earlier this year while attending a FabNow Conferance in Ft. Worth I came across a few exibits with Neo Pixel Rings. I was fascinated with the color levels and the fact they could be controlled with a single wire! [Read more…] about Building A 16×32 NeoPixel Display
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. [Read more…] about Visualizing Music With FFT
Logging Environmental Data and Charting it with Google Charts
Today I have been experimenting with the Particle Photon and logging environment data to the internet via the Data.SparkFun.com. Data.SparkFun.com is a free service for posting, storing, and reading sets of data. [Read more…] about Logging Environmental Data and Charting it with Google Charts
Arduino GPS Clock
I built the Arduino GPS Clock by Tony DiCola over at Adafruit. The clock was very cool, setting it’s time from the satellites, however, I soon started feeling like I was wasting my GPS shield by only using it to get time. So I decided to use the RGB LCD Shield which [Read more…] about Arduino GPS Clock
Matrix keypad with 7 segment display (Arduino mini project)
3×4 Matrix keypad connected to an arduino. Displaying results of key pressed on a 7 segment led display via 74HC595 shift register which reduces the required pins of the 7seg display from 8 to 3. [Read more…] about Matrix keypad with 7 segment display (Arduino mini project)
