7.3 IR receiver module
7.4 RGB LED
An infrared (IR) receiver (3) with the integrated PIN diode and a
demodulation section allows simple control over an IR remote controller
to be implemented. Thanks to the integrated demodulation section,
the captured IR signal from the remote controller can be directly used
by the host MCU. The TSOP6238 IR receiver module allows very simple
implementation of the IR remote control option, for any application.
A high-brightness RGB LED (4) option can be used to provide visual
feedback in a very simple way. There are three pre-biased bipolar transistors
on each of the RGB LED segments (red, blue, and green), allowing them to
be driven by the MCU. Three RGB LED segments are controlled by PWM
pins of the host MCU, allowing them to be individually dimmed. Thanks to
its reasonably low power consumption compared to a TFT display, RGB
LED can be used in many situations when only simple visual feedback is
required (e.g. signaling that the application is in the Stand-By mode).
