Diy watch winder by esp32 and stepper motor 28byj-48

Postby Garooc » Wed May 01, 2024 2:47 pm

I'm creating a watch winder using a Stepper Motor 28BYJ-48 controlled by an ESP32 devkit v1 over WiFi through a mobile phone, with a ULN2003 as the driver for the stepper motor.I want to use this code from github; https://github.com/mwood77/winderoo but it's written for dc motor and l298n driver. Anybody can help me to how should I change the code to can use for my watch winder?

Familiarize yourself with how the stepper works by following this tutorial
Then, you can modify how MotorControl.cpp works to move the motor. A stepper doesn't have an on/off switch, so you will need to set up a low priority FreeRTOS task that looks at a variable state (eg int8_t step_direction=-1 is anti-clockwise) and moves a number of steps in that direction, then delays to let the system process.

Hey Garooc, did you figure this out? I'm also trying to do the same.
