DIY 50km/h Value Bafang E-bike Build (Video)
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!
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.
Great idea! Please see @JamesA41 comment above regarding laser safety though. My system was used in a classroom environment where I had full control of the room, the students and where the laser was pointing. If you plan to use this sort of system on a public street I would stongly encourage you to use a different (safer) light source and to consult relavent local laws to ensure everything you are doing is above board. Thanks.
Hi. Thanks very much for this. I will certainly consider this approach on future projects. I think the ultimate aim with this is to make all sensors and Tx sources wireless using nrf24l01 modules, would synchronising the modulated signals at Tx and Rx still be possible in this case? Or would a different approach be a better bet?
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.

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