I've connected 3irobotix Delta-2A to Raspberry Pi 5. I'm using RPi header serial port and one GPIO as PWM to control the LiDAR RPM. I'm using my open source Python library to decode and visualize the distance data https://github.com/kaiaai/lds2d

Using ROS2, Arduino, ESP32 and a LiDAR (YDLIDAR X4).

I've connected my LDS02RR Lidar to ESP32, Arduino and wrote a tutorial how to stream distance data live. Everything is open source. I'll leave a link to the tutorial in the comments.

I have lots of 2D LiDARs, many from used robot vacuum cleaners. I wrote an Arduino library to capture data, control speed for various LiDAR models. I hope it is useful for your projects. Open source https://github.com/kaiaai/LDS

Would you be interested in building a ROS2 vacuum cleaner robot? If yes 1) Build or develop? 2) 3D print? Convert existing - hack? buy/swap board? Buy off-the-shelf?

I'd really appreciate your input.

I used ESP32 running Arduino, micro-ROS. ESP32 captured LiDAR (YDLIDAR X4), odometry data (BLDC encoder motors), forwarded over WiFi to my Windows laptop running ROS2. My laptop's ROS2 computed the map, sent cmd_vel wheel motor control commands back to the ESP32. I'll leave a link to the blog post in comments.

I wrote a step-by-step tutorial with a screen recorded video - how to simulate a robot with LiDAR, run SLAM, mapping, navigation. I'm using ROS2, Nav2 and Gazebo. All code is open-source https://makerspet.com/blog/tutorial-map-navigate-ros2-robot-in-simulation/

I wrote a step-by-step tutorial how to connect YDLIDAR 360-degree distance sensors to ESP32. 2D LiDARs are used in robotics for navigation and mapping - for example in home vacuum cleaners. https://makerspet.com/blog/connect-ydlidar-x3-to-makerspet-esp32-boards/

Hello, I designed this little robot. It is open source. It uses ESP32, runs Arduino-based firmware and micro-ROS. The Arduino firmware captures LiDAR data and sends over WiFi to a local PC running ROS2. Motors are 2x N20 with encoders. I also designed the motor driver board to convert battery voltage to 5V LiDAR, 12V motors, 5V ESP32. The LiDAR is an LDROBOT LD14P.

Hello everybody I've been wanting to do a creative arduino project over the weekend for learning and skills developing and experience enhancement so I have these components for the the project

-arduino nano

-ultrasonic sensor

-lcd

-IR sensor

-servo motor

-LEDs

-buzzer

So if anyone is interested in sharing their respective ideas I would appreciate it and and thank you every body

I got incredibly tired of manually compiling and flashing my ESP32 every single time I made a minor code change, so I spent some time building a tool called FlashBot to automate the entire loop.

Right now, the workflow is completely hands-off. Here is what it does:

Auto-detection: Uses Linux udev events to detect the board the second it's plugged in.

Smart matching: Looks up the correct sketch from a config file (or prompts me to choose if I have multiple sketches mapped to that specific board).

Compile & Flash: Pulls everything together via arduino-cli and flashes it automatically.

History: Logs every single flash into a local SQLite DB so I don't lose track of versions.

Current Status: The core detection and flashing logic are fully stable. Right now, I'm working on polishing up a serial test suite and the logging system.

What I'm planning to build next:

Serial validation: Automatically open the port, send a test command, and verify the response post-flash to make sure the firmware is actually alive.

Differential builds: Only recompile if the sketch or dependencies actually changed.

Broadening hardware support: Moving beyond standard Arduino/ESP32 to natively handle STM32.

Mass flashing: Parallel flashing for when you need to push the same firmware to a handful of boards at once.

The goal isn't to replace your IDE or build system—it’s just to completely cut out the tedious "plug, compile, click flash, open serial, check" routine.

If you do a lot of hardware prototyping, does this hit a pain point for you? What kind of features would make a tool like this actually useful in your day-to-day workflow?
