This helps the users to determine if the encoder is installed correctly and with enough safety margin through the whole range of motion of that particular axis. For simple fixed speed, you can just use a simple feedback loop that compares the computed speed (from the encoder) with the desired speed, and increases or decreases the PWM duty cycle according to how far it is off. One of the encoder pins is connected with 120 Ohms resistor and another pin ground. PPM and PWM receivers that have an individual wire for each channel must connect to the PPM RC port via a PPM encoder like this one (PPM-Sum receivers use a single signal wire for all channels). 32-bit Quadrature Encoder Interface (QEI) module configurable as a timer/counter.

On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about 12 of these per rotation (some have 24 or more). To avoid this, choose an encoder whose PPR is an even multiple of the value that is being measured. The transistor acts as a solid-state switch, amplifying the current available to the load. I need to use only one pin to control a servo but I also need to use every single other PWM pin on my Arduino Uno. The traditional and also most common type of RX signal is the PWM and basically PWM requires 1 cable per channel. An encoder is an electromechanical device that can measure motion or position.
