This repository contains a bunch of projects that I've created over the years for controlling various RGB (and sometimes RGBW) LED projects using arduinos uno's/teensy's. I have primarily been using the Eclipse-based Sloeber Arduino IDE which makes programming in C++ for the arduino platform much eaiser (especially if you're used to Eclipse).

• ArudinoRgbController: This contains the original Atmega328 arduino (duo/uno) code that was used on a project to control some RGB LEDs (the simple four-lead ones) based on the time from a real-time clock (RTC) input.

  The idea was to be a 'Visual Alarm', inasmuch that the LEDs would change color based on the time during the day. For this project, I also designed a circuit board with all the necessary RTC inputs and power for the LEDs which can be found on OSH Park here (images of the circuit board below).

  

• RgbControllerWithIR: This is an extension of the above ArudinoRgbController project that adds in the IRremote library in order to control the colors a little easier.

  A big note: it was necessary to move the output pin for the blue RGB from pin 11 to pin 5 because of a conflict with the internal timer libraries and the IRremote (see issue here). This change required me to physically ripup the connection between pin 11 and the blue led transistor and then white wire a new connection to pin 5. Then the IR receiver was added to pin 2.

  

• NeoPixelTesting: This project plays around with the NeoPixel RGBW LED strips. I initially bought the AdaFruit stick of eight but eventually bought a roll of them off ebay (5m of 30LEDs/m).
• MultiSegmentTesting: This is an extension of the NeoPixelTesting project that adds in the ability to split up the strip into differnt arbitrary-length segments.

• RTC_SetTime: Set/initialize the time of the DS1307 to the time at compile.
• RTC_ReadTime: Read back the time on the DS1307 with the ability to add in extra seconds with a button press.
• RTC_AlarmTesting: Test the TimeAlarm library with the DS1307.

• IrRemoteTesting: Test the incorporation of an IR receiver on an arduino.
• ButtonTesting: Test the use of the AIN0 comparator on the atmega328 for use as a button.
• HsiColor: Establishes the 'HSI' colorspace (from here) instead of direct RGB, making it easier to do crossfading (used in the ArduinoRgbController project).
