Gas sensor signal to a Arduino Mega

[Idahowalker]

Using A6? if not ground A6.

@zr1997

void loop() {

analogRead(A6);
//discard 1st reading
analogRead(sensorgas1);
int gaspin1 = analogRead(sensorgas1);
analogRead(A6);
analogRead(sensorgas2);
int gaspin2 = analogRead(sensorgas2);

clears any residual charge on the sample and hold circuit of the A:D, takes a reading, discard reading, take the real reading, repeat.

Oh yes. waiting for the answers of post #4.
