Arduino Motor Shield
I have been working with the Arduino Motor Shield. Here are some of the basic specs for the shield: Operating Voltage – 5v to 12v Motor Controller – L298P, Drives 2 DC Motors or 1 Stepper motor Max Current – 2A per channel or 4A max (with external power supply) Current Sensing – 1.65V/A Free Running ...
Intro to TSL2561
The TSL2561 is a full spectrum light sensor. I uses 3 light sensors to achieve this. I am using Lady Ada’s guide and library. In Lady Ada’s example, she uses a regular arduino, where the I2C Data and CLk are pins are pins 4 and 5. I was using a mega which its Data and ...
Working with Rotary Encoders
A rotary encoder is a digital rotary sensor. It has the capability of rotating 360 degrees and can tell you direction. This tutorial is based on Paul Stoffregen’s Encoder library and explanations. Inside of a rotary encoder are 2 contacts that are read by the arduino and the center contact grounds the encoder. The rotary ...
ChronoDot and Arduino 1.0
Recently I updated LadyAda’s RTC Library for Arduino 1.0 and older versions. In arduino 1.0 the wire library changed. It is now wire.read and wire.write. I also found that when you do use the write(0), Arduino would interpret the 0 as an integer. The new wire library does not. Because of this I had to ...
Sparkfun OpAmp Breakout LMV358
The LMV358/LMV324 are low voltage (2.7–5.5V) versions of the dual and quad op amps, LM358/LMV324, which currently operate at 5–30V. If you need to use a piezo as an analog sensor into the arduino, this is the chip and breakout board to use. Most OpAmp chips operate by looking at 2 voltages and amplifying the ...
Adafruit Stepper Gear
This Adafruit Stepper Gear has a star shaped post which make is difficult to use in a gear. In inkscape you can go to Extensions > Render > Gear and use these settings to create the star shaped post: Number of Teeth: 10 Circular Pitch: 6.4 Pressure angle: 10
Commercial Gallery
I went to 2 galleries in the SoHo area. The first gallery I went to was called the Morrison Hotel. This was a rock and roll photography gallery. It was a very relaxed environment. It mostly focused on 60s and 70s photographs. It had all of the main players, Robert Plant, Hendrix, Jerry Garcia, The Stones, etc. ...
Moma: Abstract Expressionists
The MOMA is redesigning the entrances of there exhibits. The Abstract Expressionist exhibit is a clear example of the new visual style they are going for. They are using large type with high contrasting colors. In this case they flooded 2 walls with this design. I also found it interesting that the automatic doors add ...
Prototype and Production
My thesis system is based on a simple structure. You have an input, it is interpreted and an output is produced. This system is a web application and uses javascript and ruby to create the interaction. For example, when a button or gesture is activated on a touchscreen, it turns on a light. This is ...
