With above code i believe arduino receives last rpm and speed record before i shut down the engine which is 832RPM - 13 Kmh (at this point i'm not sure if arduino receive speed value correctly because when i shut down the engine i was parked the car and speed was 0kmh), in normal case when i start the car rpm and speed value should have changed but even after started the car the value stands still,it's not changing.
#Smcfancontrol rightside stuck at 2001 rpm serial
I don't have sparkfun serial lcd, so i've changed codes according to my lcd as follow #include ĭFRobot_RGBLCD lcd(16,2) //16 characters and 2 lines of show I'm working on a hobby project with Sparkfun OBDII UART + Arduino Uno + 16x2 LCD Screen, i'm trying to read my car's RPM-Speed-Coolant Temprature-Oxy Sensor on runtime.Īs far as i understand OBDII board does all the job and it's just communicating with arduino through serial, they provided an example here : Hookup Guide
