The PCF8591 module features I2C pin header on one side, and I2C connector on the opposite side. Hence, it's more
flexible to connect the board to your development system. The board also supports I2C cascading, allowing the use of
multi module connected to the I2C bus at the same time by connecting the pin header and connector.
Please note that we will use the PCF8591 module for many of our lessons from this point on.
We'll connect modules such as light, flamed thermistor to get their value that is changing based on the environment.
The first lesson regarding the PCF8591 is just to show how to use it and connect it properly, if you'd like to continue
with the next lessons feel free to leave the PCF8591 in place.
Hardware required
For this lesson we'll need mostly the PCF8591 module.
No resistors or other parts are required. But as we stated earlier on, we'll combine the PCF8591 module with other
components later on to get their data and changing values.
