I had the pleasure of making one of these sensors at the AU London event last year. A great product which has clearly been designed with ease of assembly in mind. Great stuff.

Great suggestion, thanks. If you have a link to a good resource on interrupts please let me know.
View Instructable »Thanks for the suggestion. In this configuration would I still connect the Arduino to each of the LDRs with wires? Or use two Arduinos?

Hi. I'll try and update the instructable with component costs in the next few days.
Wow. Thanks so much for this! I'll certinaly incorporate this into a v1.2 of the code on the linked arduino.cc project. I love how I never discovered the issue with int values as the system never needed to time anything longer than 10-15 seconds!
Hi. Honestly I have not tested the latency or response time. All objects I measured using the system were moving at <2m/s over a 10m course, there were also large measurable differences in times between different cars. As mentioend in some other comments, there is better (faster/more accurate) Tx and Rx hardware, I'll probably look to make a version 2 of the system rather than test the accuracy of this one.
The circuit diagram was made using tinkercad circuits. It is more of a schematic rather than a proper circuit diagram as the exact components were not avilable in the editor.
