SignalK rudder position sensor using SensESP running on an ESP8266
I had to use an ESP8266 because I was out of ESP32's. But it works well so I've kept it running.
This device reports the rudder angle to SignalK by using a potentiometer connected to the rudder post with a belt. It uses SensESP framework version 1.07 (for ESP8266 compatability) to use sensors and report to SignalK.
