A real-time telemetry system can be useful in many situations, for example when building an electric race car. With a telemetry system, we can monitor the status of all of the car systems remotely while the car is driving. The goal was to build a telemetry system that would be simple to use and require minimal maintenance. In this article I go over the telemetry system at Team Spark and describe how you can set it up along with all our code.
