Control the switches from XIAO too
I would suggest upgrading to XIAO ESP32C3 so you can uses OTA updates to do wireless changes to the program
Also check into how musical notes are played in coding
You could write a script like a sheet of music to command the sequence exactly
For example F command may move forward one inch
R command move reverse 1 unit
B command break
So a command might be such as FFFBRRRB
