I have noticed that when looking at different types of DC motors used in various sectors, some of them come with capacitors soldered across the terminals, and others don't. Can anyone explain the purpose of these capacitors? Are they necessary for all motors, or is it a specific design choice? What ...

There is no sound from motor and not taking current, I have tried everything. There is no issue with code as well. I think as you said, I need to check the mosfets.

Hello Team, we are working on a project using 2 number of 12V kamoer water pumps and trying to control using an ESP32. We are controlling them through MOSFETs. The setup works perfectly when we are running one pump at a time. However, when we try to run 2 pumps simultaneously, one of them doesn't ...

I created one project, an Arduino Uno-based radar system. As a radar tracking device, we used an ultrasonic sensor.
The ultrasonic sensor is moved in all directions using the servo motor. Arduino IDE and Processing IDE were the software we needed to complete this project.

I have designed an Arduino-based radar system as a prototype to detect both stationary and moving objects. The system operates on an Arduino board and features various performance specifications, along with being adaptable to different sizes. The main components used in this project include an ...

As we all know, Artificial Intellenece is continuously transforming industries worldwide, automating tasks and incresing efficiency. From customer service to data analysis, machines are taking on more responsibilities than ever before. But when we think about the future, will Artifical Intellegence ...

Just one more day to go..

I am very excited about this weekly competetions. Looking forward to the challenge and seeing what topics robu will cover!

Hello everyone, I’m working on a project that involves controlling a stepper motor using an Arduino, and I’m looking for some advice on how to adjust the speed of the motor. I have an Arduino Uno, a stepper motor Nema 23 and Nema17, and an TB6560 and TB6600 driver. I am trying to get the motor to rot ...

This seems like a very interesting project! Here’s what you will need: Motor and Controller: You will need a 48v 1000W-2000W geared BLDC motor and a compatible motor controller capable of supporting human loads. Solar Panels: Depending on the voltage, select 2-4 solar panels with outputs ranging f ...

Hey, thanks for the detailed information and examples.
I've heard that a motor's torque performance reduces over time. Is this correct? If so, how much does the performance affect?
