Motive and Telefónica Advance GSMA Open Gateway Initiative, Jointly Showcasing Revenue Potential Through API-Based Phone Number Verification

Motive and Telefónica have successfully completed a proof of concept (PoC) showcasing seamless authentication using GSMA Open Gateway’s Number Verification API . Debuted at the Google Cloud booth during Mobile World Congress Barcelona 2025, this solution enables secure authentication without SMS-OTPs, reducing fraud risks and improving user expe...

HW-394 ESP-WROOM-32 BuiltIn LED Blink examples

 /*

  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO

  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to

  the correct LED pin independent of which board is used.

  If you want to know what pin the on-board LED is connected to on your Arduino

  model, check the Technical Specs of your board at:
