DIY 50km/h Value Bafang E-bike Build (Video)
Hi. I'll try and update the instructable with component costs in the next few days.
Thanks, a few people have mentioned this. As a result I will use improved Tx and Rx hardware for the version 2.
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.
I think there is a real opportunity here to further develop a project such as this for STEM. Students could be set the fairly striaghtforward task of measuring the time a model car takes to travel a set distance, then introduced to various ways to do this. There are also many "levels" to which the students can accomplish the task allowing for lots of differentiation in marking. Ironically the solution I present here is probably the most basic level, more able students could look to replace the Tx and Rx hardware with faster or more reliable components, improve the code for robustness or investigate wireless options.
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
Great suggestion, thanks. If you have a link to a good resource on interrupts please let me know.
Thanks for the suggestion. In this configuration would I still connect the Arduino to each of the LDRs with wires? Or use two Arduinos?
