Hi, im having issues with the grove alcohol sensor. According the instructions I am supposed to read the RS_air value first through serial. I was never able to connect it because uploading the sketch continuously gave errors. Today I tried again and it worked but the serial monitor gave an unreadable output. Then tried to upload again and I was back to the same failure message below. Any idea why this is happening. Also what does it mean that the sensor needs to be preheated for 48 hours? Do I need to leave it connected and powered to the arduino/grove before it will work? What will happen if I disconnect it? Do i need another 48 hours to use it?
- Already tried deleting com ports, restarting IDE, changing com ports reinstalling drivers… All no help.
