Update of the adjustable sketch for the SH1106 I2C OLED, including shrinked numbers (by 2 pixels in width and height each).

Graphics file see below for download, let me know if the numbers should be smaller.

You nailed it, Vinc. I couldn't have done that without you or taking an entire course in programming. Thanks so much. If I can help you in any way, just ask.

Thanks for the feedback.
