    PID Controller for PWM of a linear drive motor?

    I have linear drive motor that I drive with a PWM signal of frequency 1kHz. The minimum duty cycle for the linear motor to start moving without any load is 30 %. Now I am trying to design and tune a PID controller to control the position (ranges from 0 - 10000 counts). My difficulty in...

    [Solved] Motor’s Built-in Encoder Home Indicator Doesn’t Seem to Work

    I am playing around with an optical encoder built into a linear drive motor. There is a wire that is described as "Home indicator, TTL, Active high". I have connected it to PA4 on my Nucleo-F446RE (STM32), have set it to "GPIO_input" and have set the GPIO to "Pull down". I am trying to read...

    Detect-if-Connected circuit for DSLR -low voltage, low current.

    Hello, I have a DSLR camera which will have a long, wired remote trigger controlled by a microcontroller (I'm using an STM32 Nucleo). My goal is to: A. Detect that the remote trigger between the camera and MCU is plugged in, and illuminate an LED. B. Have the MCU trigger the shutter (take a...

    Which is better, STM32 Nucleo or ESP32?

    I am looking to make some projects like rover, drone etc. And after i get comfortable, i might try other types of iot projects and machine learning projects. which mcu should i choose? i have already made some projects with arduino uno and esp8266, but some people have suggested to go with other...
