Hi gays can some pls tell me in what pin should i install my DHT11 brick in the arduino Mega 2560.
also what is the pin intentions command in the syntax?

#define DHT11_PIN ?  ====> what should be the number...


thanks for the helpers

You can choose it yourself as long as the software matches the hardware.

FYI, currently busy with a small library for DHT11, not stable for publishing yet. see - http://arduino.cc/forum/index.php/topic,56413.0.html

Let me explain :
For those who managed to get the DHT11 (Temperature & Humidity digital sensor) working with the Arduino MEGA2560, let me tell you : GREAT, YOU'RE A BOSS !


P.S
when i used the DHT11 with my arduino uno everything worked excellent...

If we get the DHT11 library working on the UNO, will you test it for us on your MEGA? If so please PM me.

We have some critical timings, but make steady progress.
