RC time trial Lap Timer

Features

• LED output
• serial text interface
• set up a race(nnumber of laps), watch the lights count down, it'll output time elapsed on each lap
• on the final lap it will output the total time

Folder Structure

• src/ — Arduino sketches and main code
• lib/ — Custom libraries (if needed)
• .github/ — Copilot and workflow instructions

Getting Started

• I built this in TinkerCad

Requirements

• Arduino board (Uno, Nano, etc.)
• some type of IR trip sensor

Usage

• push code to arduino
• follow prompts that show up on the serial interface
• when the lights count down, its time to race

Things left to do

• error conditions and handling need lots of improvement
• IRL implementation and testing
