(had to guess about some hardware details, unsure if correct)

+ *      ADC12   thermal sensor
+ *
+ * Main LED power uses one pin to turn the Opamp on/off,
+ * and one pin to control Opamp power level.
+ * Linear brightness control uses the power level pin, with dynamic PWM.
+ * The on/off pin is only used to turn the main LED on and off,
+ * not to change brightness.
