This is geared towards my iPhone 4s, but really any BLE (Bluetooth 4.0) enabled device will work.The first thing is to go out and read this: https://learn.adafruit.com/getting-started-with-the-nrf8001-bluefruit-le-breakout/introductionor this: https://learn.adafruit.com/downloads/pdf/getting-started-with-the-nrf8001-bluefruit-le-breakout.pdfDone? Good.Previous tutorials have worked with the SainSmart OLED which uses a 1306 SSD (the code for this can also be found at Adafruit for their graphics - https://learn.adafruit.com/monochrome-oled-breakouts/arduino-library-and-examples).The nrf8001 …
HC-05 Bluetooth
VCC - 3.3VGND - GNDTXD - D12RXD - D11KEY - D13LED -That's it - Then you can connect to the bluetooth you desire. After you pair, the code is 1234 which may be changed by the AT commands.http://geekinc.ca/using-screen-as-a-serial-terminal-on-mac-os-x/http://www.instructables.com/id/Arduino-AND-Bluetooth-HC-05-Connecting-easily/?ALLSTEPS
SD Card and Arduino Nano
In a follow up to my last post I decided that since I was integrating these sensors on a Nano I should actually prove that as well.I took to the Arduino Nano schematic so I could figure out which pins are which.http://arduino.cc/en/uploads/Main/ArduinoNano30Schematic.pdfI don't remember where I found this PNG (one of the Aruino forum posts), …
SD Card and Arduino Mega
I purchased this awesome little SD card breakout from Sparkfun about 2 years ago https://www.sparkfun.com/products/12941 - a lot of family issues came up and I wasn't able to work on it with the kids like I wanted to. With some recent work I'm doing with sensors (more blog entries to follow) I also know I'll need to …
Skype Freezing on Windows 7
For the last couple of months I've been having a problem with Skype freezing up for 1-3 seconds every time I'd click to another application and come back. After 2 months or so of hatred for Skype, I finally found a fix that appears to be working.Open Internet Explorer -> internet options -> security -> …
New Fit Tracking App
I logged in to my FitDay app today to find that they wanted $10.99 a year for me to update my weight daily. I've been with them for almost 12 years - and said good bye. There are plenty of other (some better) apps out there - I was using FitDay as I had been …
AVR programming on a Mac
I have done a lot of my work locally on WinXP running in Parallels. I bought the book Make:AVR Programming which I cannot recommend more for anyone wanting to do AVR programming. With that, I installed http://www.obdev.at/products/crosspack/index.html - and then his examples use make files to build and flash to the AVR. I would like to see …
Cylon Eye – KITT — bitshifting with a shift register on an arduino
KITT and the Cylon Eye are very popular among those tutorials on Shift Registers.This tutorial should cover an Arduino vs AVR - This is going to suck for a tutorial. I wanted to go over some of the changes that I made to some code based off of the AVR.Let's start with the AVR - …

Wii Nunchuck update
In February of 2013 I was attempting to wire a Wii Nunchuck to my Arduino (which I did). The problem was that I thought it wasn't good enough. I liked that I could run the throttle on a train with this Arduino and code (here's the original post: http://holoprinter.blogspot.com/search/label/Wii%20Remote). What I didn't like was that it …
Laser tripwire
My son keeps asking me if we can build a laser tripwire. The idea is that a laser hits the photoresistor and if anyone breaks the laser beam then an alarm will sound. Sounds great and annoying.The circuit is very simple. A photoresistor, a 10K resistor and a laser pointer.I used this link to provide …
