The "Call and Response" method of serial communication is the most robust way to send data (such as multiple sensors) to and from the Arduino and Processing / P5. Note that is has one disadvantage: the Arduino waits until your receiving software (e.g. Processing) sends something back = i.e. "responds". So it seems frozen and... Continue Reading →
Introducing the Single-Pole, Double-Throw (SPDT) Switch SPDT switches have three legs: one common leg and two legs that vie for connection to the common leg. The common pin is in the middle. It's always connected to one of the outside pins, but which pin it's connected to depends on which way the switch is flipped. However you can use... Continue Reading →

Jller is part of an ongoing research project in the fields of industrial automation and historical geology. It is an apparatus that sorts pebbles from a specific river by their geologic age. A set of pebbles are placed on the 2×4 meter platform of the machine, which automatically analyzes the stones. The sorting process happens in... Continue Reading →
The center pin is the Shunt pin, and is usually not used - but it has a purpose.
This 50-inch-long digital timepiece is made up of 24 individual analog clocks. Each bank of six clocks forms an individual number in the seven-segment system, creating what is essentially a hacked-together digital display made out of analog parts. The piece “re-contextualizes time in a mix of old and new, analogue and digital,” explain Emanuelsson and... Continue Reading →
Here is a good introduction to capacitive sensing. Read through it to see possible uses and helpful tips for making your own. Here is my simplified and clarified revision of the example code: https://gist.github.com/ericjforman/8fd70b69a1751588aee1f9fcffa7cd42 Don't forget to install the CapacitiveSensor library from the Arduino IDE: Go to menu Sketch / Include Library / Manage Libraries, then...

Power sources connected in series result in their voltage being added together. For example, AA batteries are 1.5V each. So three in series are 4.5V (1.5+1.5+1.5). LEDs use a certain amount of voltage when turned on: Color Typical Forward Voltage (VF) Red, orange 2.0 Yellow 2.1 Green (older yellow-green variety) 2.2 Blue, white, ultraviolet and newer “true”...
