If the arduino is set to run the program after receiving power then what happens when I move onto another project that doesn't use the same setup. In some cases this could potentially blow something. Should I hit reset on the board between each project? I don't see any mention of this in the book. I feel weird when I breadboard out the next project with the last project still loaded onto the chip. Should I disconnect everything from the breadboard and load the next sketch prior to building it on the breadboard? Really confused about what to do between projects. :(
If I hit reset on the board while Project 03: Love-O-Meter is running then it simply restarts the Project 03 sketch. It doesn't default back to the basic Blink sketch. How to ensure safety so that I don't accidentally blow up my Arduino between projects? Should I manually load in the Blink sketch between projects?
