Once the limit switch has triggered, you could damage your equipment by repeatedly driving it in the direction that forces it into the limit switch, as re-engerisation after the limit switch is ...

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.

Fortunately, both the speed and direction of a DC motor can be controlled via an Arduino microcontroller. Let’s get into details. Direction control A circuit known as an H-bridge may be used to alter ...

In this project we are controlling DC Motor speed using PWM and we will be able to control the speed of DC motor with potentiometer and we can adjust the speed by rotating the knob of Potentiometer.

Does it just stay there and do random things? Nope, of course not! [Guido] built it with a unique control box, two Arduino 2560’s and an Xbee to communicate between them.

Write & Test an Arduino sketch for reading from x4 ThriftyBot absolute encoders and x2 limit switches and sending this data over serial bus to the Jetson #94 ...

Learn how to build a Arduino Opta DC motor controller with a pushbutton switch and a programmable human machine interface (HMI).

A contest for hardware design enthusiasts to develop a motor control system project with the Arduino Portenta H7 board.
