Fun with the Arduino

Finally, we are getting to a subject that I almost feel confident about.  The C programming language is a common and very useful skill for engineers to know.  The arduino's use of "C" to operate means that I can help others..... so if you have any questions please don't hesitate to ask. 

This is my version of the blinking in response to the sensor circuit..... a buzzer was added to become a back up sensor.... lol
