Abstract: Disclosed in some examples are devices, methods, and machine-readable mediums for reliable control of IR LEDs. In some examples, a microcontroller running firmware controls whether the LED is activated or not by use of a disable signal. The microcontroller enables or disables the operation of the LED based upon a user's proximity to the LED, a watchdog timer, and a confirmation that only trusted software is executing.
