In this example we will connect and LDR up to our Arduino and display the reading on a bargraph display, think of this as a low cost type of light.
One of the fun things about Arduino's is coming up with projects to use Arduino's and various sensors or modules. In this project I was thinking about an example that.
In a previous example, we did a basic copy of the Arduino capacitance shield but hey outputting to the Serial Monitor is a bit boring, so how about we pick.
In this example we will add a DS18B20 temperature sensor and an SD card. We will then log the results of the sensor to a file on the SD Card.
