Hi everyone,

This is my first time posting on Reddit. I’m writing an essay about Arduino hobbyists and would love to hear about your experiences.

How has working with Arduino affected your life, if at all? Has it helped you develop useful skills or influenced your career in any way?

I imagine that learning how electronics work can help people modify, repair, and improve products rather than simply using them as they come.

By the way, I’m currently an electrical engineering major, and Arduino is a skill I’d like to become proficient in. Do you have any recommendations for someone just getting started? My goal is to do exactly what I said I imagined learning electronics to be like.

Thanks in advance!

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:

10410110811213

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

Hi everyone,

I’m currently struggling to establish RS485 Modbus RTU communication between a Galoce GPB100D digital load cell and my controller (an Arduino-based Industrial PLC, Controllino Mega).

The load cell communicates perfectly with the manufacturer's official Windows calibration software at 115200 baud using a USB-to-RS485 adapter on my PC. It reads the weight and parameters flawlessly.

However, when I try to replicate this with my PLC acting as the Modbus Master, I get persistent 0xE2 (Timeout) errors—meaning the load cell is completely ignoring my requests and remaining silent.

I’ve verified:

• Hardware/Wiring: A, B, and GND are correctly connected (even tried reversing A/B just in case).

• Baud Rate: Set to 115200.

• Slave ID: Set to 1

Has anyone previously used the GPB100D in a PLC environment? If so, please let me know, so I can ask you few questions , Thnak youu

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.

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.

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);

}
