PWM for servo pulse is on a three wire system (Pos, Neg, and data). The pulse is a series of different length square waves sent to the servo or ESC in a certain length of time. This pulse is then translated by the servo or ESC as a "position" it (...) (20 years ago, 2-Feb-05, to lugnet.robotics, lugnet.technic)

In my ongoing quest to control Lego robots by radio, I've uncovered some receivers made by GWS that work with a standard model airplane transmitter, and have 4 channels of standard PWM (pulse-width modulation) output. For example, see (URL). But now (...) (20 years ago, 2-Feb-05, to lugnet.robotics, lugnet.technic)
