I am using analogue inputs A0, A1 and A2 on a Micro and find that if I configure digital pins 18 and 19 as outputs, then the inputs to A0 and A1 are pulled strongly to ground. The Arduino Micro pinout diagram shows pins 18 (A4) and 19 (A5) connected to 32U4 Port F2 and Port F3 - which do not exist …

There are enough incorrect diagrams floating around for all kinds of boards :frowning: Anyway, A0, A1 and A2 are pins 18, 19 and 20 as below code shows void setup() { Serial.begin(57600); while(!Serial); Serial.println(A0); Serial.println(A1); Serial.println(A2); } void loop() { } Also…
