Know How... 213: Arduino Controlled Lighting

We build an Arduino that can control, brightness, red, blue, and green LED's individually using potentiometers. Lightduino Parts List4 x Potentiometers $6.98Favorite WS2812 LightUBEC (For future use) AssemblySet 4 potentiometers into the breadboardDaisy chain 5v and GND onto the outside pins of each potentiometer (MAKE SURE NOT TO CROSS 5V and GND!)Connect the center pin of each potentiometer to Analog pins 0-3Connect the WS2812 light stick to 5V and GND, and the data pin to Digital Pin 3 PracticalsWe're running everything from on-board power for this small-scale experiment, but we'll need a seperate power source once we scale up our lightingWe're using an Uno for the prototyping stage, but we're going to use a smaller Atmel board for the final projectWe want to run the finished light from a single 3s batteryWe will get slight variations in our analog values because our jumper wires are slightly looseThis would be a good time to use digital rotary encoders Lightduino Programming https://www.dropbox.com/s/wpv3gpi40cyxoja/KH213_Lightduino1.zip?dl=0 Hosts: Fr.
