PWM signal over long(ish) distances?
heyoo!
so trying send control signal arduino pin 10 servo 30 feet away. touring band's stage design , trying make modular possible.
ive made box send arduino signal , power servo (6v, via external power supply) servo via telephone jacks (rj11) & telephone wire (four conductors @ 22 gauge. i'm using 3, positive, negative, , control). take signal directly out of arduino breadboard power supply , power servo , ok. take signal , connect phone jacks, plug in 30 ft phone cord between them , jerky unprogrammed movement servo. ive checked connections , tested , convinced kind of data transmission problem, not stemming wiring or poor connections.
what should do?? need amplify arduino signal somehow travel distance uncorrupted? bad idea send on telephone cable?
thank muchhhhhh, totally stumped right now..

i've done same thing on cat3 telephone wire (solid wire) 12'. wire cat3 solid wire or flexible telephone extension cord?
