    Hello, my name is James Douglas and welcome to AB9VH Electronics.  I am an Amateur "ham" Radio Operator, callsign AB9VH.  I have been tinkering with electronics and many other things since I was young.  I enjoyed programming before I was in high school.  Many hobbies have come and gone since then.  A few years ago a friend of mine introduced myself to the Arduino platform.  I have been hooked ever since. 

    I have created many Arduino projects and I keep looking for uses of that credit card sized micro controller.  In 2011 I started to develop a project that incorporated accelerometers.  I wanted to make a few different prototypes and I was constantly removing shields and sensors, never able to keep a design together for any length of time.  All of my projects needed a display, and wiring them up was a pain in the rear.  I was using extra digital pins for supplying power and ground.  I really needed to find a different Arduino compatible controller to fit my needs, one with more available pins.  I couldn't find one.  A fellow ham, Gary W9XT, asked why I didn't make my own.  Why did I not think of that sooner!  That's when my first micro controller design was born, the LCDuino.

    I have also designed accelerometer breakout boards and shields.  I have  used them in many different applications, including vehicle and firearm mounted applications. 

    Many thanks to the Arduino Team for inspiring my inner maker!!!
