Microduino Light indicator-Digital tube(TSL2561)
|Language:||English • 中文|
This tutorial will teach you to use the TSL2561 sensor and use digital tube to dispaly the result.
TSL2561 light sensor:
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.
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.
Cover the TSL2561 sensor with the hand, the digital tube's value will decrease, put the hand away, the value will increase.
