Infrared (EBM020) component
The Infrared sensor board contains both an IR transmitter and receiver. The transmitter is enabled via a digital control signal and the receiver provides an analogue output. By enabling the transmitter and reading the variable voltage output of the receiver it is possible to measure the distance of a reflecting object in the region of 1cm to 10cm.
Examples
Sample program using the EBM020 - Infrared sensor.
Transmits a signal and determines distance from reflected value

Property reference
Input ADC Channel
This property is of type Single analog pin and can be referenced with the variable name CHANNEL.
Analog input channel for the IR receiver
Output Enable Pin
This property is of type Single digital pin and can be referenced with the variable name CONTROL.
Pin used to control the IR Transmitter
