Arduino simulator of engine RPM and/or Alarms. Used to test SH-ESP32 and/or its Engine Hat add-on board.
This simulator sets PINs on an Arduino board high in a certain frequency to simulate engine RPMs and alarms for low oil pressure and high cooling water temperature. This was tested with an WeMos D1 Mini ESP8266.
GPIO pin mapping available on link above.
WEMOS
- D5 bruin - D3 oliealarm
- D6 rood - D2 RPM
- D7 groen - D1 koelwater
- DNG zwart - GND D1
Not sure why i wrote up this mapping
- Yellow on pin 2 (rpm)
- Not sure what i did for oil and temp alarm.
