- Wheel Encoder Firmware Version 3 (updated 2024-12-09)
Arduino Uno is a microcontroller board based on the ATmega328P and one of the most popular Arduino models. It has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.
The UNO can be programmed with the EZB firmware for various capabilities when connected to ARC. The tutorial to program the EZB firmware can be found HERE.

I seen that, Thanks for your time DJ.
You can try other pins as well, but I can’t verify they work. Arduino is a bit unstable because there’s so many hardware types and open source has no accountability for quality
