Arduino Garage Door Opener – Prototype

IMG_20130624_224956

I’m done with school now, degree and all, and still have a couple of weeks before I’m officially on the job.  In the meantime I’ve been fooling around with some home automation hardware, specifically the veralite from micasaverde.  While I haven’t spent too much time with the veralite yet my first impression is that it …

MSGEQ7 Arduino Library

The digital section of my Bright Light Controller is fully functional and I’ve gone ahead and made a library to help interface with the MSGEQ7 IC.  As of Version 0.1 the library will probably only function on a 16MHz or slower Arduino.  This shouldn’t be too difficult to modify, but I haven’t gotten around to …

How to Repair an Aruino Nano

Arduino Bootloader Programming

  Step 1: Purchase a new Atmega. This is the version of the chip from digikey  Atmega328P Step 2: Carefully desolder the old processor.  I found that is very easy to lift the pads in this process.  If I were to try it again I’d probably try using a heat-gun. Step 3: Solder the new proccessor …

Bright Light Controller Schematic

Bright Light Controller Schematic

I have recently stumbled upon a service called BatchPCB which offers cheap single run PCB prototyping.  I’ve decided to give them a try since it seems safe for someone whose never designed a board from scratch.  After some digging it seems like going to their supplier, Gold Pheonix, would work out cheaper if you’re looking …

Arduino Power Supply Selector

Arduino Uno Rev3 Power Supply Selector

I’ve been looking through the Arduino schematics in search of a circuit to perform automatic power supply selection in the case that there are two available supplies. I had convinced myself that there was a design flaw in the Arduino Uno selector, however upon further inspection it seems it should work just fine.
