Mar 31, 2016 · I'm trying to control the speed of a DC motor using the circuit which i have attached along with this code: - int motorSpeed = 30; int motorPin = 9; void setup(){ } void loop(){ analogWrite(motorPin, motorSpeed); delay(2); } The motor runs but I cannot change the speed by adjusting 'motorSpeed' Can anyone see what I'm doing wrong here? Thanks

Oct 9, 2017 · Hi Arduino Uno I have a linear actuator motor for opening and closing a door by reversing the 12V polarity. I use an H-Bridge to reverse the voltage for open/close of the door. Works great! In my code sample below in order to stop the voltage to the motor I use: // turn off motor pinMode(motorPin1, INPUT); pinMode(motorPin2, INPUT); delay(2000); by changing pinMode from OUTPUT to INPUT. Works ...

Nov 29, 2022 · I'm currently programming an Arduino program for my final school project, and I need help. The task is to control two stepper motors. One of the two motors has two buttons, when the button is pressed, the motor goes one step to the right, when the other one goes to the left. The second motor has three buttons, the first two for the same thing, but when the third is pressed, the motor goes to ...

Jan 1, 2016 · I got a Arduino Uno Starter kit and I want some help in learning how to use it to drive a 2 phase 4 wire stepper motor. It's those very tiny steppers with drive voltage of 3-5V, used in digital cameras I think. I want the shaft to swing like a pendulum, a certain degree clockwise and a certain degree counterclockwise, and repeat... I'm totally lost on how to start this. I …

Nov 15, 2014 · Sometimes when the pot is turned all the way down, the program reverts back and the motor stops and "0" is printing. In any other position, sometimes the button will work, sometimes it won't. I believe the motor is causing some sort of feedback into the system. Right now, the motor is in parallel to a snubber diode and is attached to a transistor.

Aug 8, 2024 · Hello, I am using a UIROBOT UIM2040CM servo stepper motor. I would like to control using an arduino and CAN bus. Here's the documentation for the motor: Manual_UIM342 2024.07.31 (1).pdf (1.9 MB) I would like to please know the CanID for speed and how to send commands for speed as the manual is confusing and I haven't ever worked with CAN before. #include <SPI.h> #include <mcp_can.h> // Define ...

Nov 21, 2022 · moveToPosition = -1 * moveToPosition; // reverse direction stepper.moveTo(moveToPosition); // move motor one revolution moveTo() is an absolute move so you should use stepper.moveTo(0); to go back to the start. If you move to negative numbers you will try to go past the beginning and jam against the motor.

Dec 8, 2018 · Some DC motor drivers have a current output. To help find one we need to know the rated voltage and stall current of your motor. Place a shunt (low value resistor) in series with the motor. The voltage dropped by the resistor is proportional to motor current (see Ohm's law). Depending on the setup, amplification of the output may be necessary.

May 10, 2017 · Hallo! Ich möchte im Rahmen eines Schulprojektes einen Motor per Knopfdruck steuern. Dabei soll der Motor bei Knopfdruck einfach 2,5 Sekunden in eine Richtung laufen und danach wieder aus gehen. Verkabelt habe ich die ganze Sache nach dieser Anleitung: Den Taster nach Schritt 10: Ein Taster als „digitaler Spannungsteiler“ Den Motor nach Schritt 13 Mein Programm sieht bisher so aus: int ...

Feb 13, 2009 · Could I add a choke to both lines, as I am using two relays to control which motor lead sees power (normaly both are tied to ground), similar to the last circuit seen at grumpy's motor tutorial page. Also, when I have put large cremaic caps on the motor leads, they explode quite spectaculary even though they are susposdly rated for higher ...
