I’m before making an Arduino module onto my LADA VAZ 21925 “Kalina2 Sport” car, to display Ambient Temperature, Coolant Temperature, Fuel level (and with AM2320 module the indoor air temp and humidity).
Now the detection / display of indoor temp & humidity is solved, I’m interested in, what is Your opinion our sketch, where are the ELM327-READ-PID routines.
I will pair the HC-05 with MEGA 2560 like this: http://bibi21000.gallet.info/index.php/fr/accueil/82-racine-fr/public-fr/domotique-fr/arduino-fr/181-arduino-et-bluetooth.html Connections are the same.
What do You think? Is my sketch good, maybe I will cause damage in MOTRONIC of my car, or the sketch is wrong?
I could check this ino by the Arduino IDE, with success.
