I purchased the “SunFounder New Uno R3 Project Super Starter Kit For Arduino UNO R3 Mega2560 Mega328 Nano”. The first two sketches I tried had problems:
Standard Blink didn’t blink, just lit the LED attached to pin 13. Adding a resistor to ground from digital pin 13 fixed this – LED on board then blinked as expected.
OmniWheelControl sketch from Make Magazine “reset” as soon as a “pulseIn” command was executed. Upon the “reset”, the setup(); section re-executed, followed by the portion of the loop(); section up to the first “pulseIn” command. This sequence repeated rapidly. The reset appears to be the same thing that happens when the reset button is pushed – the program starts over from the top. Replacing the Sunfounder “Arduino” with a real Arduino fixes the problem 100%.
Do I have a bad unit, or do all Sunfounder boards have these problems? Searching didn’t uncover anyone else having these issues. Thanks.
