Hi, i am embedded system engineer with 11 years of experience, i can help you build precise timer to track the car. If i am not mistaken, the display will be inside the car? May be we can discuss more about it to find the suitable sensor, like the track size, the end track, and some other detail to build the board effectively

With my hands-on experience in Arduino, C Programming, Circuit Design, Electronics, Embedded Systems, Microcontroller, and PCB Layout projects, I have successfully brought to life a wide range of complex systems like the one you need for your track timing project. I have the practical knowledge to identify and implement the most appropriate start/stop trigger mechanism for highly precise lap timing for you, ensuring no missed triggers or double-counting. Moreover, my proficiency in real-time data processing and display will guarantee that you receive millisecond-accurate lap records for each driver on time. My familiarity with 16x2 LCDs that can auto-update and store previous laps along with the best lap make me exceptionally fit for this job. I'll also provide you with an easy-to-follow quick-start guide with clear calibration and testing instructions at the track. Lastly, what makes me unique is not just the skills but also my approach to integrating diverse technologies. My capability to bind AI systems and hardware components would be a great asset for your project as it is focused on merging Arduino and AI-based techniques. With me on this project, you can expect not just precise lap-timing but also an intelligent system where data would be recorded perfectly and used effectively to derive insights for better performance in the track-day cars.

@alluankit01

Hi, I can develop your Arduino lap timer system with accurate start/finish sensor detection, millisecond lap timing, LCD display, reset button, wiring diagram, parts list, and testing guide. The best solution is to use an interrupt-based trigger from an IR beam or magnetic reed sensor, add debounce/filtering to prevent double-counts, then store and display current lap, previous lap, and best lap on a 16x2 LCD in real time. I’m comfortable with Arduino, C/C++, embedded timing logic, LCD modules, sensor integration, interrupt handling, debounce logic, push-button reset, wiring diagrams, and prototype testing. Deliverables include: * Arduino `.ino` sketch * Sensor trigger logic * Current/previous/best lap timing * LCD live display * Reset button function * Double-count protection * Wiring diagram * Parts list * Calibration and quick-start guide I’ll focus on reliable timing so the system does not miss or double-count laps during your 10-lap test. Best regards Ankit

@masummsnr

Hi, Reliable trigger capture is where most Arduino lap timers fail; your ten-lap test lives or dies on debounce. My plan: a hardware interrupt on the start/finish sensor plus a short lockout window so cars can't double-count, and each lap on the 16x2 LCD within a second of the line. I'd use an IR beam track-side, non-contact and easy to align. The sketch stores current, previous, and best lap, with a push-button reset that clears the session, no reboot. You get a commented .ino, a wiring diagram, a local parts list, and a track calibration guide. I build connected embedded systems on ESP32 with sensor integration, so this sits squarely in my work. Timeline: 6 days, tested against your ten-lap acceptance run. First step: confirm the sensor and LCD you want, then I share the wiring layout. Regards, Nurullah Al Masum

@shahzaib81829

Hi. I have completed similar Arduino-based timing and sensor projects and can provide a working simulation of the lap-timing logic, LCD display, and trigger handling before you confirm the project. I will develop a clean, well-commented sketch with millisecond lap timing, current/previous/best lap storage, automatic LCD updates, trigger filtering to prevent missed or duplicate laps, and a push-button session reset. You will also receive a clear wiring diagram, parts list, and quick-start guide for calibration and track testing, with the system designed to register ten consecutive laps reliably and display each result within one second.

@zzalimuhammad

I can develop a precise, reliable Arduino-based lap timing system for your track-day car that meets your 10-lap testing requirements without missing or double-counting triggers. Here is my proposed implementation plan: Hardware and Sensor Selection: I recommend using an active IR beam sensor pair or an optical switch paired with an I2C 16x2 LCD display to minimize wiring clutter and simplify setup. Firmware Design: Write a clean, well-commented Arduino sketch utilizing hardware interrupts for millisecond-accurate trigger capture, combined with a software lockout window (blanking time) to completely prevent false double-counting. Session and Data Management: Keep track of current lap, previous lap, and best lap in memory, refreshing the LCD within milliseconds of passing the start/finish line. A dedicated interrupt or debounced push-button will reset the session data cleanly without rebooting the board. Deliverables: You will receive the ready-to-upload INO sketch, a clear schematic/wiring diagram, a concise parts list for easy local sourcing, and a quick-start guide covering trackside calibration and testing.

@adrianb026

Hi there! I can build a precise, reliable Arduino lap timer system for your track day setup within 2 days. ​Technical Approach & Solutions: ​Sensor Recommendation: Standard reed switches or simple IR sensors often fail at high track speeds due to bounce and narrow pick-up zones. I recommend an Active IR Transponder or Laser Beam-Break Receiver wired to an Arduino Hardware Interrupt (attachInterrupt) to guarantee sub-millisecond precision. ​Zero False Triggers: I will implement a configurable software lockout window (e.g., ignoring triggers for 10–15 seconds post-line) so shadow flickers or trailing cars won't register double laps. ​Non-Blocking Logic: The sketch will use millis() and avoid delay() entirely, ensuring the 16x2 LCD updates instantly without lagging the timer. ​Deliverables Included: ​Clean, fully commented .ino sketch (tracks Current, Previous, and Best Lap + pushbutton reset). ​Minimal schematic/wiring diagram. ​Local parts sourcing list (Arduino Uno/Nano, I2C LCD, Sensor, Reset Button). ​Quick-start guide for trackside calibration and testing. ​Ready to start immediately upon award! Let me know if you'd like to proceed with the laser recommendation.

@wassimkroud

You need a lap timer that records one clean event per pass, updates the LCD within one second, and survives the ten-lap acceptance run without missed or duplicate triggers. I will lead the sensor selection, map the wiring, implement non-blocking millisecond timing, and deliver current, previous, and best-lap handling with a push-button session reset. The first checkpoint will lock down the Arduino/LCD models, maximum passing speed, sensing distance, and mounting geometry. I will then build trigger filtering and a configurable lockout window, test bounce, rapid retriggers, timer rollover, and reset behavior, and deliver the commented sketch, wiring diagram, parts list, and calibration guide. A staged bench test before the track run will reduce the main risk: choosing a sensor that behaves well in code but poorly in the actual lighting or mounting position. What maximum speed, sensing distance, and mounting arrangement should the trigger support?

@yasserMl4R

I have years of experience with arduino and i'm pretty sure i'd be able to complete this project for you delivering the .ino code file you asked for with a technical file with the components you need and a schema for the circuit... I'll give you as many revisions as you want to make adjustments as you please, and help you with any confusions. And on top of that if I don't finish the job within the time limit, i'll give you the final files for free so that the next person you hire would take significantly less time. Also the 7 days are the very maximum, depending on challenges and modifications i have to work with, it could go down to less than 4 days.
