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.

For Red, consider putting in a horn.
if the situation is dire (loss of oil pressure), shouldn't you PUSH notification to the driver to shut things down vs waiting for the driver to glance over at the lights (POLLING)?

My https://www.lairdtech.com/products/cl4490-series has showed up. NJMP in 6 days, there is a slim chance.

Re: Lemony Cheap DIY Arduino Remote Telemetry

Any radio people going to NJMP? I can use some in-person advice about my setup.

An audible alarm is also in the works. I currently have the horn hard wired to the coolant level switch, but could easily have the arduino control the relay that drives it for anything of our choosing.
