Week 12:

 Output Devices

Task

I have this week worked with output devices and completed the following:

Flashing Charlieplexed LED Breakout Board

Creating a Standard RGB-Output Board

I decided to create a RGB-output board following the example given in Neils lecture.

Milling RGB-Output Board
Populated RGB-Output Board
Fully Functioning RGB-Output Board
Burning the Bootloader
Uploading Code

Red & Green Charlieplexing

In an attempt to control as many red and green LEDs with as few pins as possible i decided to create a board with charlieplexing. The breakput allows for placement of the LED in a casing, that could be integrated in my final project, where the the LED could work as a timeline where red/green illumination would indicate weather or not the furniture is free/booked.

I abandoned this design and opted for a serial connected network-enabled design, which I name the Infinite Bridge - read more about it on either my project development page or my portfolio from week 14.
