REMOTE CONTROL SYSTEM OF STEPPER MOTOR BASED ON THE ESP32 DEVELOPER BOARD

The stepper motor is a unit of control system to achieve the goal convenient use and precise control, which greatly facilitates our life improves level modern high-tech industry. In particular, multiple motors may be joined in work together with remote-control program, flexibility applicability equipment. real life, are used more often. For example, 3D printer, using three stepping at same time, x-axis, y-axis, z-axis, can determine left side space accurately print three-dimensional object we need. By adding system, movement time replace humans complete complex high-precision work. endoscopes often medicine, when endoscope needs make micro adjustments position, remote real-time adjustments. project ESP32 uses python language write programs based on microPython firmware realize introduced. speed direction adjusted controlled by pulse signals. clock generate signal PWM, comes WiFi module, support control. adjusting duty cycle PWM program. Combined products, performance this designed product stable reliable. has timers their interrupt efficiently simultaneously. And module easily conveniently. According principle motor, half-step full-step realized. Additionally, step mode cosine function motor. A user-friendly web application been developed four motors, allowing you remotely four-engine simple way
