Use the Inex Photo-Transistor Board in two different modes:

• Analog: The output voltage will be decreased when it detects infrared light.
• Digital: The output is logic "0" when the infrared light is detected.
• Detects lights with a wave length of 1mm
• 2-mode operation: analog or digital
• Can detect the candle light in Fire-Fighting Robot challenges
• Use it with the Inex Infrared LED board
