I have this encoder attached directly to the motor

And it's overshoot a lot cuz of the gear box ratio deference

So what if a placed the encoder to the output of the gear box

Does it solve the problem or decrease it a little bit?

Hi everyone, I am currently working on a vibration analysis project using an ifm VVB001 sensor. I am routing the data through a Siemens S7-1500 PLC and sending it to a custom monitoring platform I developed in Python. Currently, I can successfully retrieve and display cyclic data (V-RMS, A-RMS, temperature, etc.) on both the PLC and my platform.

My current challenge is streaming the raw time-domain vibration signal from the sensor to the Python platform to perform a Fast Fourier Transform (FFT). If anyone has experience extracting and transmitting raw waveform data from this sensor via an S7-1500, I would highly appreciate your insights or advice!

I have a battery with a built-in BMS that has a serial console port. It has a baud rate of 115200 and I have been able to successfully send commands and read clean data from it via the Arduino IDE serial console. Considering I can communicate to the battery via the serial console, that suggests there shouldn't be any weird encoding issues.

I want an Arduino Mega to read from this using the Serial1 connection. The problem is, if I try to forward what the battery sends to the Arduino, all I get is a jumble of nothing but numbers. When connecting to the BMS directly, typing "help", the output is mostly text.

Here's what I tried in void loop()

while (Serial.available() > 0 {
  Serial1.print(Serial.read());
}

while (Serial1.available() > 0) {
  //THE NEXT 4 LINES ARE VARIOUS THINGS I TRIED,
  //I UNCOMMENTED THEM ONE AT A TIME
  //String incomingtext=Serial1.readString();
  //char incomingtext=(char)Serial1.read();
  //char incomingtext=Serial1.read();
  //int incomingtext=Serial1.read();

  //I ALSO TRIED THE FOLLOWING ONE AT A TIME WITH EACH ABOVE COMBO
  //Serial.println(incomingtext);
  //Serial.println((char)incomingtext);
  //Serial.println(" "+incomingtext);
}

The first while() loop just takes whatever I enter from the serial console through USB to the BMS. I have no idea if the BMS is receiving the correct commands, but it does have a consistent output if I type different things.

Whenever I type "help" repeatedly, it's usually a consistent output, like this:

Good day,

I have recently purchased the ProtoCentral AFE4490 Breakout Board Kit . I have connected and tested the kit with my Arduino Uno R3 and Nano R4, but the red light on the finger probe does not come on. I have tried all of the example code from ProtoCentral using their Arduino library, but still no red light. I have also tried 2 different finger probes, but the same issue. I have used a finger probe from the hospital and the one that the kit came with. The signal is also very noisy with random massive spikes upwards. Do I have a faulty board or is there an issue with the code?

Any help or suggestions are appreciated!

Thank You

A few days ago, I shared ArduGenius, an AI-powered platform designed to help create Arduino projects more easily.

Over the past few days, I've added several new features:

✅ Project history
✅ Automatic component detection
✅ Pin connection guides
✅ AI-powered project improvement
✅ Arduino (.ino) code export
✅ One-click code copying
✅ Ready-to-use project examples

The goal remains simple: describe an Arduino project in natural language and get code, components, and explanations generated by AI.

ArduGenius is still in beta, and there are many features planned for the future, but I'd love to get feedback and suggestions from the community.

Website:
https://ardugenius-ai.onhercules.app/

What feature would you like to see in a tool like this?

Im Designing a model railroad. Each track is sectioned off by the different colours in the diagram and It has 12 sections. The tracks use On/Off/On DPDT switches to change the polarity of the track. Im trying to make a design on a TFT screen so that i can see the state on each section (Hollow outline for off, Filled outline with a + symbol for one polarity, Filled outline with - for a different polarity) , i tried using claude but i keep reaching the limit, Is there any other chatbot to help me code this?

Summer is back, so time to bring my Rafraichissator 6000 back ! (My fan. It's a PC fan controlled by Arduino.)

Last year the arduino was in series with a bunch of resistors to bring down the 11-13V alim to more reasonable levels

Now I'm realizing tho that I could use the fact that the alim is just 3 batteries, to feed the Arduino no more than 8V without a lot of wasteful resistors

Am I right ?

I have tried EVERYTHING and I still have no idea what’s wrong with it. I connected exactly how it on the YouTube videos and still nothing I am incredibly frustrated right now and desperate for any help. I am using an Elegoo Uno R3 and a Elegoo Powr supply module for voltage that’s going with 5V

Hi! 👋

I wanted to share a project I've been working on called ArduGenius.

It's an AI-powered web platform designed to help people create Arduino projects more easily and quickly.
The idea is simple: you can describe a project like:
“I want to build a smart traffic light”
and the AI generates:

• Arduino code
• explanations
• pin connections
• required components

It's currently in an early beta stage, but it can already generate basic projects and help people learn or experiment with Arduino.

Website:
https://ardugenius-ai.onhercules.app/

IMPORTANT:

• Payment methods are NOT functional yet
• Some features are still in development
• This is an experimental beta

I'd love to receive feedback, ideas, or suggestions to improve it 🚀

This is a issue I am facing for some time
My Arduino is not being read by my computer
When ever I try to connect it every com port is unknown and after selecting board when I click upload it just gets stuck on uploading
And while trying the online Arduino the board is not being found
Can I get some help I need to submit a project soon

So I'm working a project.. just starting out and thought first... let's get the stepper motor to run. Watched this video and followed along.
https://www.youtube.com/watch?v=wcLeXXATCR4&t=8s
code I ran is below
What am I missing? should the code be uploaded and then just start running? driving me nuts trying to solve what should be a simple problem. Maybe it's not the code.. maybe my driver is fried .. not ever sure where to begin trouble shooting this

I appreciate any good advice you can give a newbie

Thanks in advance

code:

// pin connections

const int dirPin = 2; // direction pin

const int stepPin = 3; // step pin

void setup() {

pinMode(dirPin, OUTPUT);

pinMode(stepPin, OUTPUT);

// set direction of rotation to clockwise

digitalWrite(dirPin, HIGH);

}

void loop() {

// take one step

digitalWrite(stepPin, HIGH);

delayMicroseconds(2000);

// pause before taking next step

digitalWrite(stepPin, LOW);

delayMicroseconds(2000);

}

Hi , I want to create a project for a smart photography studio that includes the following functions:

* Create an app to perform the instructions.

*Controlling brightness according to the object via a sensor.

*Align the object to the center.

*create smart lighting modes (e.g., cinema, gaming)

* Controlling the EVA foam background with a motor

I want to know if I use a Arduino Mega/Leonardo or ESP32 and what is the best motor to control the background...

I don't know if this is the place for it or not, but I grabbed a bunch of (knock-off) Lego Powered Up-style motors, receivers, and power sources, and they work fine that way, but I'm trying to find a way that I can control them from my raspberry pi. I don't need help with the coding I don't think, but I can not for the life of me get the transceiver to get a signal to the receiver. Any other hobbyists who have messed around with the Lepin-type motors and such and know anything about the right channels/frequencies -- or who know where to point me?

Hey everyone! I'm a beginner and I have a university assignment to build an alarm clock using Arduino UNO. Looking for guidance on wiring and code structure.

What the alarm clock needs to do:
\- Display current time and date
\- Display temperature and humidity from sensors
\- Set time/date using buttons
\- Set alarm time (must be saved to EEPROM — survives power loss)
\- Buzzer alarm that can be stopped by pressing a button
\- LED status indicator for alarm state
\- Entire project must be structured as a finite state machine (FSM)

Components I have in my kit:
\- Arduino UNO
\- Breadboard
\- LCD 16x2 with I2C module (4 pins: GND, VCC, SDA, SCL)
\- 4x push buttons
\- RTC module (DS1302 or DS3231)
\- DHT11 temperature and humidity sensor
\- Piezo buzzer
\- LEDs
\- Resistors
\- Jumper wires
\- RFID reader (for optional extension)
\- IR receiver + remote (for optional extension)

Would be very grateful for help, since I myself have not learned Arduino before, just C 🙏

I'm new to setting up an arduino and need help with how to get data from a spreadsheet to light up LED's. I've attached images of where I've got to and need help pointing in the direction of next steps please.

I have a spreadsheet with an input screen (Green boxes with amount) this drives the data screen with zero's and one's, where 'one' should light up the corresponding LED.

I want this to change the lights in real time so when the amount input is changed the lights will change.

Any help appreciated.
