MQCalibration was not declared in this scope, what`s …

2017627 · nexus1212 You''re using a 3V Arduino. It looks like all the patterns are correct, but it''s just not getting things right. A lot of the unprintable characters in ASCII are at the start of the table, so I''m thinking maybe you have a serial connection that is expecting 5V as the ''high'' voltage and what it''s actually seeing is so borderline that it''s not always registering correctly.
