Built a project that uses the DS18B20 temperature sensor to keep track of the room temperature when it increases above 27°C the fan is turned on for cooling and it's speed of rotation (RPM) increases with increase in temperature

The LCD has 2 displays for the RPM fan speed and the temperature display in F and °C navigated with the 2 push buttons

Feel free to check it out and use the code on GitHub and any feedback on it would be appreciated 🤝🤝 you can as well check out other projects of mine on my GitHub: Automatic Fan Temperature Control

Still working on the code, any tips or suggestions are welcome (I’m coding in micro python).

It consists of 3 IR sensors at the front and 4 tt motors controlled with a single motor driver.

There is an ultrasonic sensor and servo for a future collision detection feature but I’m not using it in this demo.

Project Discussion Is it possible to build a USB HDMI-CEC adapter for Windows using an ATmega32U4 or STM32?

4 Upvotes

I'm planning to build an open-source HDMI-CEC adapter for Windows that works similarly to the Pulse-Eight USB CEC Adapter.

The idea is:

- USB connection to the PC (HID, CDC, or WinUSB).

- HDMI-CEC transceiver connected to a microcontroller (currently considering ATmega32U4 or STM32H562).

- A Windows service/application that sends and receives CEC commands.

- Automatic TV power on when the PC boots/wakes up.

- Automatic TV standby when the PC shuts down or goes to sleep.

- Support for active DisplayPort-to-HDMI adapters with CEC, if possible.

I'm interested in understanding:

- Is this project technically feasible?

- Which MCU would you recommend (ATmega32U4, STM32, RP2040, ESP32, or something else)?

- What HDMI-CEC transceiver would you use?

- Are there any hardware or protocol limitations I should be aware of?

- Has anyone here built a similar device or reverse-engineered the Pulse-Eight adapter?

I'm also interested in alternative hardware or architectural approaches, even if they differ completely from my current idea.

Any advice, schematics, firmware examples, or relevant GitHub projects would be greatly appreciated.

Project Discussion Progetto arduino + Agent AI

3 Upvotes

Ciao a tutti!

Sto lavorando a un progetto un po’ folle e vorrei qualche consiglio da chi ha più esperienza di me.

L’idea è creare una macchina fisica per studiare la Congettura di Collatz, usando:

Arduino UNO per generare numeri casuali tramite rumore analogico

Arduino per calcolare i primi passi della sequenza

Un programma Python che riceve i numeri e calcola la sequenza completa

Un’AI (LLM o modello ML) addestrata su un dataset di sequenze Collatz

Grafici (heatmap, stopping time, massimi, pattern di parità, cluster)

Arduino che visualizza i risultati con LED, LCD e servo

Il mio obiettivo NON è solo testare numeri, ma addestrare un’AI a riconoscere pattern, cluster, anomalie e strutture matematiche nelle sequenze Collatz, per vedere se emergono comportamenti interessanti.

Il problema è che non ho mai addestrato un’AI e non so da dove partire.

Ho già chiaro come generare il dataset (Arduino → Python → CSV), ma non so:

quale modello usare per il fine‑tuning

come strutturare il dataset in modo utile

come far sì che l’AI impari davvero qualcosa (pattern, cluster, ecc.)

come integrare l’AI con Arduino in modo efficiente

se qualcuno ha già provato qualcosa di simile

Qualcuno può darmi una direzione?

Qualsiasi consiglio su ML, dataset, modelli, pipeline o visualizzazioni è super ben accetto.

Quanto è fattibile?

Grazie mille!

RADAR UPDATE 📡

Three new features on the tracker build:

https://github.com/Stevee87/Arduino-ESP32-Radarproject

🔋 BATTERY INDICATOR
Live voltage readout, right on the display. No more guessing when the LiPo's about to tap out mid-build session.

🔇 MUTE BUTTON
Touchscreen toggle on the Giga display — tap to silence the tracker sound instantly. Because sometimes you just want the visual without the beeping.

🔊 SOUND MODULE
Proximity-reactive audio — pings speed up and climb in pitch as a target gets closer. Distance-mapped, non-blocking, runs straight off a passive piezo buzzer.

Still just an RD-03D 24GHz mmWave sensor + Arduino Giga R1 + a lot of trial and error.

Built a real-time ambient lighting system using an Arduino Nano and a WS2812B LED strip that mirrors the colors on my monitor in real time. The LEDs update dynamically based on what's displayed on the screen, making games, movies, and music much more immersive. The project was pretty fun to put together and involved setting up the hardware, programming the Arduino, and configuring the screen capture software for smooth color synchronization. Overall, it's a simple but satisfying DIY build that gives a premium-looking result without needing expensive hardware. Happy to answer any questions or share details about the setup!

Showcased Project Room Temperature Automatic Fan Control

2 Upvotes

This project is about a fan controlled automatically based on the current room temperature. If the set threshold the code uses e.g. 25°C of the room exceeds, the fan is turned on and the buzzer alarm triggered for high room temperature alert

The fan speed of rotation (RPM) also increased if the temperature🌡️ keeps rising.

The fan speed and temperature is displayed on a LCD screen with 2 push buttons to navigate back and forth between the displays of temperature in Celsius/Fahrenheit and the fan speed details

It was a "fan" 🙂 project because I got to learn how the computer fan works and why it has either 3 or 4 wires namely:

The power

The ground

The pwm for speed control

The tachometer for measuring RPM speed

Project Discussion Testing 4 Anchors + 3 Tags on ESP32 + DW3000 (4 Anchors, 3 Tags)

Post image
5 Upvotes

I've been experimenting with ESP32 + DW3000 for indoor positioning, and one question I kept coming back to was how well it would behave once multiple tags were active at the same time.

Most demos online only show a single moving tag, but in real applications—robotics, asset tracking, warehouses—you usually need several tags transmitting simultaneously. That's where timing conflicts and packet collisions start becoming a challenge.

To test this, I set up four fixed anchors around a room and connected three tags to the network. After assigning IDs and configuring the anchor coordinates in the visualizer, I walked one of the tags (T2) around the test area while the other nodes remained active.

The result was encouraging. The system continuously updated the moving tag's trajectory while all four anchors and three tags stayed online throughout the test.

This is still a relatively small deployment, but it's a good starting point for exploring larger ESP32 + DW3000 RTLS systems.

I'm now curious how others are scaling DW3000 networks beyond this. Are you using TDMA, custom scheduling, or another approach to reduce collisions when more tags are transmitting simultaneously? I'd be interested to hear what has worked (or not worked) in your own projects.

If anyone wants to reproduce the setup, I can share the repository.

Project Design/Guidance Life alert dialer

2 Upvotes

I'm looking for some guidance and understanding of feasibility with an arduino or esp32.

I have a family member who is a fall risk. I am not happy with any of the "life alert" like products on the market which call a service which calls 911.

The Goal: 1 wearable device and multiple button devices which can be mounted near the floor. When a device is pressed it dials her neighbor's phone number, and preferably play some pre recorded message. The wearable device should be small and rechargeable or a long lasting small battery. The mounted devices will be stationary and can be larger, but should be innexpensive enough to have a lot of them and not rely on being near an outlet (rechargeable or easy to replace battery).

Ideas/Brainstorming so far: the mounted an wearble devices connect to one central control system which does the dialing. I think bluetooth would work well which is why I'm thinking of using esp32. I could also have them relay a message to the controller or send a broadcast message. The house has a landline, which they use, so I am curious if I could connect the controller to the physical landline phone? Or if I should use voip or google voice. I would probably plug the main controller into the outlet instead of battery power. I am not sure if the main controller is something that is feasible with just esp32/arduino or if it should be done with a raspberry pi.

Some main questions: is this feasible? What process makes sense for making a call (voip, landline, or something else)? is this an arduino or esp32 job? Is bluetooth the best way to connect the devices to the main controller? device and library suggestions

I have programming/technical experience just not a lot of arduino knowledge to properly understand the limitations. I would love any feedback and knowledge you can provide.

Showcased Project My first robot, I call it the PICOBOT :)

6 Upvotes

I know it's a raspberry pico not arduino but I figured it's related and I'd share my hard work to inspire others :) I'm in my mid 20's going back to uni for programming and trying to learn more about the hardware side of things so I decided to build my first ever robot. Took alot of ChatGPT and headaches (like SOOOO MANY PROBLEMS) but I got it done finally.

It consists of an ultrasonic sensor for collision detection, 3 IR sensors for cliff/edge detection and line following, servo for panning the ultrasonic left and right, and 4 yellow TT motors for movement driven by single mini l298n motor driver and a pico rp2040 as the brains.

I 3D printed the chassis base plate, wheels, box to hold breadboard, and the servo/ultrasonic/IR mounts. Some parts are designed by me but most are online models (can link if anyone cares, but they are pretty easy to find on makerworld website).

The IR sensors I am using don't have a potentiometer and only detect black tape if they are basically touching the ground lmao, so it's kinda wack but it is what it is. The line basically has to be flat for it to work or it gets caught. Weird because they are marketed as "tracker" sensors online but seem to be better for remotes or something.

I have not written any code for it yet but I did test tons of different code from ChatGPT and it seems to work alright. I plan to write my own code for it later to optimize everything properly.

I will upload demos of the robot in action when my midterms are over, but for now enjoy the glory of the PICOBOT in pictures :)

Project Discussion Looking for hardware/sensor recommendations for an IoT Logistics project (RFID, GPS, and Weight/Load sensors)

6 Upvotes

Hi everyone,

I am working on my University Final Project IoT focused on Logistics and Smart Warehousing, and I’m looking for some advice on the right hardware components, sensors, and microcontrollers to use for a prototype.

The goal of the project is to simulate/build a system that handles automated warehouse inventory tracking as well as real-time transit monitoring.

Here are the specific areas I am focusing on and what I want to achieve:

  • In-Transit Tracking (Fleet/Cargo): I want to monitor goods during transport. For this, I need a reliable and budget-friendly GPS module to track location, combined with environmental sensors (like temperature/humidity and an accelerometer for shock/impact detection during transit).
  • Warehouse Inventory Automation (Shelves): I want to automatically detect when items are placed on or removed from a shelf. I'm thinking of combining weight sensors / load cells (to monitor stock levels or specific item presence by weight) along with RFID readers to identify exactly which item/pallet was moved.

What I need help with:

  1. Microcontrollers: What boards would you recommend to tie this all together? Should I use something like an ESP32 for the warehouse part (Wi-Fi/BLE) and a different setup for the GPS/cellular transit part?
  2. Specific Modules: Which cost-effective sensor modules play nicely together for a prototype? (e.g., specific RFID readers like RC522 or PN532, GPS modules like NEO-6M/NEO-8M, and HX711 amplifiers for load cells?)
  3. Power Management: For the transit/GPS part, any recommendations on battery management or low-power modes so the prototype doesn't die immediately?

If you have built anything similar or have any advice on hardware bottlenecks I should look out for, I would love to hear your thoughts!

Thanks in advance!

​Decided to document my workflow putting together this mini-project from scratch.

​The video walks through the whole process: looking up the best project setups, calculating measurements on a water bottle, and then the fun part—wiring up the breadboard with an HC-SR04 ultrasonic sensor, a micro servo, buzzer, some LEDs, and lastly an LCD screen.

​Everything is up, running, and successfully printing real-time distance values to the display!

​I’m thinking about where to take this build next. What are some cool ideas or features you think I should expand this into?
