Earth Rover 

Part IV

Android / Arduino Interface Code Update.

Code update for android and arduino files. Note xml files are added on to end of Java code in same file to save space. You will need to cut and paste them to the correct xml files.On my google drive:

The update incorporates two way serial comms over BT. RC control from Android with bumper sensors controlling interrupts to stop the Rover and display which bumper was triggered on the display. Note I am using button action:  if (event.getAction() == MotionEvent.ACTION_MOVE)
which means you have to keep you finger or stylus moving slightly to keep sending the signal. A small safety feature.

It is an update but it isn't working fully. The interrupts are triggered incorrectly by the movement of the robot's motors. I am working towards finding out why and a solution. Please let me know if you have some ideas.

Father's Day

My Dad, Jack Turner Born 1936 
He was the first person in our family history to get a decent education, thanks to his working class parents who struggled in impossible times to get him there.
He volunteered for the RAF as a firefighter, during the years when National Service was compulsory. He served 25 years in the W. Yorkshire Fire Service and saved many lives, nearly copping it himself a couple of times. 
It's thanks to him I became a scientist and a geek. He bought me a chemistry set when I was five and taught me about how chemicals can interact to make fire and fire-hazards. To me, at that age, means fireworks. He let me have a lab in our attic and bought me more chemistry sets, a microscope, electronics kits and other cool science stuff.
 Thanks Dad for being a great Dad, a hero, and an inspiration.
