'''Product overview'''
TSL2561 is a light-digital converter which converts light into digital signal output, contains I2C interface or SMBus interface. Each device connected to a photosensitive diode tube and infrared photosensitive diode on a single CMOS integrated circuit. The integrated circuit has 20bit dynamic range optimal light response ability.

Features：
*Programmable to set light intensity's threshold, when the actual light intensity exceeds the threshold sends a interrupt signal;
*Digital output meets standard SMBus (TSL2560) and I2C (TSL2561) bus protocol;
*Analog gain and digital output time programmable control;
*1.25mm x 1.75mm ultra small encapsulated, in low power mode, the power consumption only has 0.75 mW;
*Automatic inhibition 50 Hz/60 Hz light wave.

==Program==

https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Sensor/TSL2561Segments

==Debug==
Step 1：Download TSL2561 library, and uncompress it to libraries folder of Arduino IDE, then restart IDE.
http://learn.adafruit.com/tsl2561/use

Step 2：Copy the code to IDE and compile it.

Step 3: Set up circuit, as follows:

Step 4：Run program.

Step 5：Observe digital tube, cover the light sensor with the hand and then let it see the light again, look at the digital tube change.

==Result==
Cover the TSL2561 sensor with the hand, the digital tube's value will decrease, put the hand away, the value will increase.
