Hi everyone, I have a mistake that is making me sleepy. a few days ago I was doing a project for atomizing university. I was able to make the code work just fine. As I have my raspberry pi some time decided to buy a bigger SD card. so I had to format and install a new system.
So far so good. When I installed NODE and NPM I had a bit of trouble, but searching I was able to learn how to handle this installation. In other words, I can now have all NODE versions.
But after installing everything right, install the libary, when I started my code, it started to give error. And I did not understand why. I’m running after this mistake for a while, but all I do is no use. I’ll make my code available here. Please help me.

//*** SMARTPHONE DOORLOCK ***//
// ************* PARAMETERS *************** //
//
// Parameters: unlockedState and lockedState
// These parameters are in microseconds.
// The servo pulse determines the degree
// at which the horn is positioned. In our
// case, we get about 100 degrees of rotation
// from 1ms-2.2ms pulse width. You will need
// to play with these settings to get it to
// work properly with your door lock
//
// Parameters: motorPin
// The GPIO pin the signal wire on your servo
// is connected to
//
// Parameters: buttonPin
// The GPIO pin the signal wire on your button
// is connected to. It is okay to have no button connected
//
// Parameters: ledPin
// The GPIO pin the signal wire on your led
// is connected to. It is okay to have no ledconnected
//
// Parameter: blynkToken
// The token which was generated for your blynk
// project

@Kefbr the error message contains a reference to line 62 of your sketch i.e. the definition of the Blynk connection with the Blynk token at line 42. The token declaration looks ok but I have had occasions where hidden characters appear in sketches / scripts if you copy and paste code.
Double check that the token is exactly as it’s shown in your sketch.
Thank you for the quick response and your attention. this same code worked before I formatted my raspberry. The problem would be in the token that blynk gave me?
comic … I searched the internet for a ready project of anything, installed all the modules and called. To my surprise it worked quietly.
I thought to myself: what if I put my elbow on top of this created code?
was what I did, put all the variaves and everything right (just did not bring the variable that starts the blynk)
And guess what? It worked … follow the code …
If you analyze, there is NO difference.
How is this possible? LOL
