hi everybody, I am trying to upload this sample code generated by blynk to my arduino uno wifi rev2 board. Please help me rectify the error.

You have to download and install wifi.h first.

You have a programming problem, not an upload problem. Hence your topic has been moved to a more suitable location on the forum.

Please don't post images of errors or of code in future. Post text as text and use code tags (the <CODE> button on the forum above the editor text box).

after downloading wifi.h and compiling the code again, here's the new error

What's the solution??

IF you want to solve the error then

open 'BlynkParam.h' from your Arduino\libraries\Blynk\src/Blynk/BlynkParam.h and then replace all 'atoll' with 'atol'.
