Re: Lemony Cheap DIY Arduino Remote Telemetry
I built a prototype system using two buttons and two LEDs - red for PIT NOW! and green for READY TO RACE. I may also add a yellow or blue LED to alert the driver to look out for something unusual.
I haven't played with the cellular radio yet, but my plan is to use SMS as the primary communication method from the car to the team. This will allow all team members to be alerted without needing any special software.
We have the exact same setup- green (OK), yellow (heads up, check your gauges/call in on radio), red (pull over ASAP and kill the engine).
I might have to think about SMS expansion. The serial interface allows high data rates and is simple, but I expect obstructions will cut out data on the back half of tracks. I figure since the driver is being warned with the status LEDs, the updates as the car comes around every lap will let the folks in the pits see gradual changes that are adverse, i.e. oil pressure degrading or temperature climbing.
