Help with Displaying 3-Digit Codes on OLED using Arduino

Hi everyone, I’m a beginner working on an IoT project and need some help.
I’m trying to display a 3-digit code on a 0.96-inch OLED display using Arduino. The code should be sent from a mobile or laptop through a web interface.

I tried using Adafruit IO, but I’m only able to send and display one digit at a time. I want to send and display all 3 digits together.

Can someone guide me on how to solve this? Or please let me know if this is not the right group to ask—I’d really appreciate it if you could point me to the right place or person.
Thanks in advance!

    Instead of sending digits as integer , you can send a value as string (like “123”) and parse it on the Arduino side.
