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 connected a SHT21 temperature and humidity sensor to an Arduino - http://www.arduinolearning.com/code/sht21-humidity-and-temperature-sensor-example.php. This was a bit basic as the data was sent via the serial port, so lets add an LCD to display the temperature and humidity readings, there are plenty...
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.

In this example we will create a simple clock example using a DS1307 breakout, a keypad/LCD shield and an Arduino Uno The DS1307 real-time clock is a low-power, full binary-coded decimal clock/calendar. Address and data are transferred over the I²C bus.The clock/calendar provides seconds, minutes,...
