I tried uncommenting each of the three Pre-compiler Directives, but same result: successful upload, but just the blinking lights. I don’t know if I need to add or amend code to this sketch to make it work or if it is a hardware problem. Sample sketches 1 and 2 load, but don’t seem to be doing anything. ![]() ZumoBuzzer example 3 will make the orange LED blink 8 times in sequence, pause and continue another 8 blink sequence, but that is all. Not successful at all in making any sound using any of the ZumoBuzzer sample sketches in the library. I am very new to Arduino and have no experience writing code, but have managed to get my new, factory assembled Zumo to move with the ZumoMotors sample sketch and play around with timing of movement.
