#connect component potentiometer1 -  scale 3000-7000 as int for connection to servo
#   tips - analog v digital pin naming conventions: A->ADC->read_u16(),D (Pin.OUT is default, might need Pin.IN)->value()
#   extension - replace potentiometer with joystick and use horizontal (HORZ) or vertical (VERT) axis output

#connect component servo1 - 3 wires, PWM, pulse freq, typically ~1-2ms/50HZ (ie 1-2ms/20ms) PWM range 3000-7000 / 65536
