[SOLVED] Slider seems to crash arduino

Issues and Errors

@Costas can you show your final code here? I’m having some overflow issues with my esp+mega+blynk sliders :stuck_out_tongue_closed_eyes:

@zeeko I think the sketch below was the final version but it wasn’t with ESP. Not checked the sketch but it might help you.
