Question 1 year ago on Introduction

Is there any instruction on how to do it with the new app? There doesn't seem to be any way to get the old app working without a pre existing login

Hi, I am using this with a Mac. When I tried to upload the sketch "Arduino_Serial_USB", it gives the error message saying that it doesn't recognize the file/directory "BlynkSimpleStream.h". I understand the tutorial is designed for Windows but do you know how I can fix this error message?

Thank You :)

Thanks it worked one more question if you have the time. My sketch is verified but won't upload to my Arduino. Is this just due to the fact that it is a big file? Should I expect to wait the whole night? Or is there something else wrong? It just constantly says "Uploading"

Thanks Again (I know you have exams)

Arduino just take 3-4 seconds to upload a sketch.if sketch compiles then it definitely uploadable.
are you able to upload simple blinking LED sketch.??
If not then Check
1)have you select right COM port.
2) driver's installed properly or not.
3)if both not work then your arduino is damaged.
