As you can see we only need 3 connections to the sensor, since one of the pin is not
used.
The connections are: Voltage, Ground and Signal which can be connected to any Pin
on our MEGA2560.
Code
After wiring, please open the program in the code folder- Lesson 12 DHT11
Temperature and Humidity Sensor and click UPLOAD to upload the program. See
Lesson 2 for details about program uploading if there are any errors.
Before you can run this, make sure that you have installed the < SimpleDHT> library
or re-install it, if necessary. Otherwise, your code won't work.
For details about the tutorial on the loading of library file, see Lesson 1.
