Atsuwe, Bernard Aondofa Abstract: A remote-controlled stepper motor using RF module was designed and simulated. This design of remote-controlled stepper motor consists of mobile section and a static section. The mobile section comprises of a keypad connected to microcontroller with Liquid Crystal Display (LCD) display. The keypad is used to input the stepper angle and the signals are been sent to the microcontroller that converts these signals to a serial data and transmits them via Transmitter (TX) module. While the static section has a Receiver (RX) module that continuously scan for the signals from TX. Upon receiving the transmitted serial signal the RX module send it to the microcontroller at the static section to decode these signals and turns the stepper motor to the appropriate angle via stepper motor driver. The results from the simulations show that stepper can be controlled remotely using RF module.
