Hey guys I have a mega with max6675 connected to an ungrounded k type thermocouple. Using this code
but instead of pins 8,9,10 I’m using 50,53,52. I am constantly getting nan or erratic readings
I can’t get a consistent reading.
It was ages since last used and cant remember if I previously tested it. It is inbetween an hm10 and adxl345 which work fine. Would bad soldier joints or modules being to close cause an issue.
