Abstract-An algorithm for control of several servo motors by a microcontroller is presented. The limited number of programmable timers on the majority of microcontrollers presents a problem for multiple generation of timi ng pulses. Two software approaches are discussed in the paper and experimental r esults given for operation of a set of small servos using a single timer.
Key words-PWM; servo; multiple; timer
