1 year ago Here is my doorlock.js file:
var BLYNK_TEMPLATE_ID = 'TMPLISLOZuxh'
var BLYNK_DEVICE_NAME = 'Door1Front'
var BLYNK_AUTH_TOKEN = 'my token is in here btw I have just hidden it for security purposes'

//*** 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
//

Blynk library version: v.1.10 IDE: VSC IDE version: v.1.69 Board type: Raspberry Pi Model 3B+ Additional modules: Node.js / NPM
Scenario, steps to reproduce
Upon attempting to run my js file, I am greeted with an error which states that my token is invalid. I have tried creating new devices on the Blynk dashboard and updating my token, with no luck at all.
Expected Result
I was hoping that the Pi would connect the the Blynk dashboard.
Actual Result
When I run my JS file, it connects for a split second, and then disconnects: Here is the output:
